Anger is a common, normal, healthy emotion felt by most people. It can range from mild irritation or annoyance to full-blown rage or physical violence.
Hepatitis B is a liver disease caused by the hepatitis B virus.
The spread of hepatitis B occurs when blood from an infected person enters the body of a person who is not infected. Hepatitis B is spread in the following ways:
Sexual contact is the most common reason for the spread of hepatitis B infection in the United States. The spread of hepatitis B as a result of heterosexual sex (vaginal intercourse) makes up about one-third of new infections in adults. The risk of spreading hepatitis B increases if either person has multiple sex partners, a history of a sexually transmitted disease, or has sex with an HBV-infected person. About one-quarter of new infections occur among men who have sex with men.
Hepatitis B is also easily spread by sharing drugs, needles, or "works" when "shooting" drugs. The risk of infection from contaminated needlesticks is much greater than the risk of spreading HIV by this method. In the United States, illegal drug use injection accounts for about 16 percent of new hepatitis B infections.
Other types of percutaneous (through the skin) exposures, including tattooing and body piercing, have also been reported to result in the spread of hepatitis B. Unsafe injections in medical settings are a major source of hepatitis B infection in many developing countries and might be a risk for United States residents traveling abroad, if medical care is required in settings that do not have good systems in place to prevent transmission. Hepatitis B is also spread through needlesticks or sharps exposures among healthcare workers and others.
Although hepatitis B can spread from an infected mother to her baby during birth, breastfeeding has not been associated with transmission.
Hepatitis B can also be spread during childhood. Most early childhood spread occurs in households of people with chronic (life-long) hepatitis B infection, but transmission has also been seen in daycare centers and schools. The most likely way that the spread of HBV occurs during early childhood involves contact between an infected person's body fluids (e.g., blood from cuts or wounds) and breaks in the child's skin.
Hepatitis B can be spread also when an infected person bites another person who is not infected. Hepatitis B can be spread also by an infected person pre-chewing food for babies, and through contact with infected personal-care items, such as razors or toothbrushes. The virus remains infectious and capable of spreading infection for at least seven days outside the body, even if blood or other fluids is not visible.
Hepatitis B is not spread through:
People with chronic hepatitis B infection should not be excluded from work, school, play, childcare, or other settings.
People usually begin to show symptoms between 45 to 160 days (average 120 days) after infection.
There are two stages of hepatitis B infection: acute, which typically occurs within the first six months of infection, and chronic disease, when the hepatitis B infection remains in the body for a long time. Acute infection can sometimes, but not always, lead to chronic disease.
Not everyone with acute hepatitis B has symptoms; about 7 out of 10 newly infected adults whave signs or symptoms and children under 5 years of age rarely show any symptoms.
Signs and symptoms of acute hepatitis B might include:
People who have such signs or symptoms generally feel quite ill and might need to be hospitalized. In 2007, there were an estimated 43,000 new cases of hepatitis B in the United States.
Hepatitis B is very serious.
This serious condition is discussed below. Even though people might eventually recover from their acute infection, a feeling of tiredness and poor health might last for months.
People with chronic hepatitis B infection are infectious and can transmit the virus to others. Usually, chronically infected people do not feel sick and do not realize they are infected. They generally have the hepatitis B infection for their entire lives. They are also at high risk of developing chronic liver disease, including cirrhosis (scarring of the liver), liver failure, and liver cancer.
An estimated 15-25 percent of people with chronic hepatitis B infection eventually develop serious liver disease. Chronic infection is responsible for most hepatitis B-related sickness and death, including cirrhosis, liver failure, and liver cancer. When people are infected at a very young age, these forms of liver disease do not appear usually until young adulthood or middle age.
About 5 out of 100 unvaccinated people in the United States will contract hepatitis B infection sometime in their lifetime. Approximately 1 million people have a chronic infection. Most of these people do not know they are infected.
In the United States, an estimated 3,000-4,000 people die each year of hepatitis B-related liver disease, and another 1,000-1,500 die each year of liver cancer as a result of infection. Worldwide, the medical consequences of chronic infections are a huge problem. Approximately 350 million people around the world are chronically infected and approximately 1 million of these people die each year from cirrhosis leading to liver failure or liver cancer. Overall, hepatitis B is the 10th leading cause of death worldwide.
Between 1990 and 2005, the overall occurrence of reported cases of acute hepatitis B declined. In 2006, the estimated number of new hepatitis B infections was about 46,000--a decrease from an estimated 232,000 new infections in 1990.
The overall decrease in the occurrence of acute hepatitis B in the United States is most likely due to the increased use of hepatitis B vaccine and changes in behaviors among at-risk populations in response to the HIV/AIDS epidemic. The greatest decline in cases was among children and adolescents, the group with the largest increase in hepatitis B vaccination coverage. Reporting of hepatitis B still remains a problem as many people do not exhibit recognizable symptoms.
Despite the dramatic decrease in the number of new HBV infections in the United States, chronic hepatitis B infection remains a major problem. About 1 million people have chronic infection currently and most of these people do not know they are infected because they haven't been tested. Most cases of chronic infection in the U.S. are found in immigrants or refugees from areas of the world with moderate or high rates of hepatitis B. Some of these areas of the world include Asia, Africa, the Pacific Islands, and Eastern Europe. People from these areas of the world should be tested to find out if they are chronically infected.
A blood test called is needed to diagnose acute hepatitis B. There are additional blood tests for hepatitis B that determine other aspects of infection. These other blood tests can tell whether or not a person is currently infected and whether or not a person has been infected in the past.
If the tests indicate a person has been infected in the past, testing will also determine whether the person has developed protective antibodies to the virus (i.e., they have gotten over the infection and will not get infected again [this is called immunity]) or whether they still have virus in their blood, indicating they might have a chronic infection.
|What hepatitis B blood tests are available?|
Hepatitis B surface antigen
|A positive test means that you have hepatitis B virus in your blood and can pass the virus to others. You could be recently infected or you could have chronic (life-long) infection. A negative test means that you do not have the virus in your blood.|
|Antibody to hepatitis B surface antigen (anti-HBs)||A positive test means that you are immune (cannot get hepatitis B). This positive test occurs when you were either vaccinated with hepatitis B vaccine successfully, had a recent dose of hepatitis B immune globulin (HBIG), or you had the actual infection. Only vaccination or actual infection provide long-lasting and usually permanent immunity (means you will not get hepatitis B again). Anti-HBs produced by HBIG lasts only a short time (about 3 months).|
Antibody to hepatitis B core antigen
|A positive test means you currently have or have had infection with hepatitis B virus at some undefined time period. The positive test has no relationship to having received hepatitis B vaccine; however, the test might be used prior to vaccination to see if you had already been infected.|
IgM antibody subclass of anti-HBc
|A positive test means that you were recently (within 6 months) infected with hepatitis B virus.|
Hepatitis B "e" antigen
|If this test is positive, you are infected with hepatitis B virus and have a large amount of hepatitis B virus in your blood. You are at increased risk of serious liver problems due to your chronic hepatitis B virus infection.|
Antibody to hepatitis B "e" antigen
|This blood test might be positive if you have chronic hepatitis B virus infection or if you have already recovered from your infection. If have chronic hepatitis B virus infection and this test is positive, this means that you have low levels of hepatitis B virus circulating in your blood and are at lower risk of liver problems due to your chronic hepatitis B virus infection.|
HBV Deoxyribonucleic acid
|When this test is positive, it means you are infectious to others and the hepatitis B virus is active in your body, possibly causing liver damage. The test is often used to determine success or failure of drug therapy if given for chronic hepatitis B virus infection.|
There are several Food and Drug Administration (FDA)-approved medications that might help a person who has chronic infection. These medications don't usually get rid of the virus, but they might decrease the chance of the infected person developing severe liver disease. Not everyone is a candidate for these medications. Researchers continue to seek additional cures for hepatitis B. There is no treatment (other than supportive care) for people with acute hepatitis B.
If you've been diagnosed with chronic hepatitis B, there are some simple measures you can take to protect your friends and loved ones.
If you think you've been exposed, don't delay. Contact your doctor or clinic. If you have not been vaccinated, it is recommended that you receive treatment with hepatitis B immune globulin (HBIG), a blood product containing protective hepatitis B antibodies. You should also get the first dose of hepatitis B vaccine as soon as possible, preferably at the same time as the HBIG is given, but at a different site on your body. Following this, you will need to complete the full hepatitis B vaccine series (usually a total of three doses over a six-month period).
No. If you get an acute case of hepatitis B and recover, you should have protective antibodies in your blood that will prevent any further infection with HBV. The medical literature does report possible mutant strains of HBV infection, but these are rare and would be highly unlikely to occur.
Hepatitis B, A and C are different viruses that attack and injure the liver, and can cause similar symptoms. Usually people get hepatitis A infection from close personal contact with an infected person or from ingesting food or water that has been contaminated by feces. Hepatitis B and C are spread when an infected person's blood or blood contaminated body fluids enter another person's bloodstream. Hepatitis B and C infections can cause chronic liver problems. Hepatitis A does not.
There are vaccines that will protect people from hepatitis A and B infection. Currently, there is no vaccine to protect people from hepatitis C infection. There are medications that are approved by the FDA for treatment of chronic hepatitis B and C. If a person has had one type of viral hepatitis in the past, it is still possible to get the other types.
The hepatitis B vaccines (Recombivax HB® and Engerix-B®) used in the United States are recombinant DNA vaccines, which means they are produced by inserting the gene for hepatitis B into a medium from which it is grown, harvested, and purified. Hepatitis B infection cannot occur from receiving the vaccine.
The Centers for Disease Control and Prevention (CDC), the American Academy of Pediatrics (AAP), the American Academy of Family Physicians (AAFP), the American College of Physicians (ACP), and American College of Obstetricians and Gynecologists (ACOG) recommend this vaccine.
Hepatitis B vaccine should be given to infants (12 months of age and younger) in the thigh muscle. Either the thigh or the upper arm muscle may be used for young children. The upper arm muscle is the preferred site of administration for adolescents and adults. Hepatitis B vaccine should always be given into the muscle regardless of the age of the patient.
Hepatitis B vaccine, usually a three-dose series, is recommended for all children 0-18 years of age. It is recommended for infants beginning at birth in the hospital. All older children who did not get all the recommended doses of hepatitis B vaccine as an infant should complete their vaccine series as soon as possible. Most states require hepatitis B vaccine for school entry. Adolescents who are just starting their series will need two or three doses, depending on their age and the brand of vaccine used.
Adults at increased risk of acquiring hepatitis B infection should also be vaccinated. In addition, the vaccine can be given to any person who desires protection from hepatitis B.
Any adult who wishes to be protected from hepatitis B infection should be vaccinated without having to acknowledge a specific risk factor.
Short-term travelers to regions (Asia, Sub-Saharan Africa, Amazon Basin, Eastern Europe, and the Middle East) in which there are moderate to high rates of hepatitis B are typically at risk for infection only through:
The Centers for Disease Control and Prevention recommends hepatitis B vaccination for travel to any of these places, regardless of the length of stay.
Yes. Hepatitis B vaccines have been demonstrated to be safe when administered to infants, children, adolescents, and adults. Since 1982, more than an estimated 70 million adolescents and adults and more than 50 million infants and children have received at least one dose of hepatitis B vaccine in the United States. The majority of children who receive this vaccine have no side effects. Serious reactions are rare.
Of those children experiencing a side effect, most will have only a very mild reaction, such as soreness at the injection site (fewer than one out of three children) or low-grade fever. Adults are slightly more likely to experience such mild symptoms. Serious allergic reactions following hepatitis B vaccination are rare.
After three properly administered doses of vaccine, at least 9 out of 10 healthy young adults and more than 9 out of 10 infants, children, and adolescents develop protective antibodies and subsequent immunity to HBV infection.
There are three basic reasons for recommending that all infants receive hepatitis B vaccine, starting at birth.
First, babies and young children have a very high risk for developing chronic HBV infection if they become infected at a young age.
It is estimated that about 1 out of 3 of the nearly 1 million Americans with chronic HBV infection acquired their infection as infants or young children. Those with chronic HBV infection are most likely to spread the infection to others. Infants and children who become chronically infected have an increased risk of dying prematurely from liver cancer or cirrhosis.
In contrast to other vaccine-preventable diseases of childhood, HBV infection in infants and young children usually produces no symptoms. Thus, the small number of reported cases of hepatitis B among children represents the tip of the iceberg of all HBV infections in children. For every child with symptoms of hepatitis B, there are at least 100 HBV-infected children with no symptoms---hence the increased risk to spread the infection to others without knowing it.
Second, early childhood infection occurs. About 16,000 children under 10 years of age were infected with HBV every year in the United States before routine infant hepatitis B vaccination was recommended. Although these infections represented few of all HBV infections in the United States, it is estimated that 18 out of 100 people with chronic HBV infection in the United States acquired their infection during early childhood. Clearly, infections occur among unvaccinated infants born to mothers who are not HBV-infected. In addition, unvaccinated foreign-born children account for a high proportion of infections. More effort needs to be placed on vaccinating these unprotected children.
Most early childhood spread of HBV occurs in households where a person has chronic HBV infection, but the spread of HBV has also been recognized in daycare centers and schools. The most probable ways children become infected with HBV are from skin puncture (e.g., biting) or from having their mucous membranes or cuts and scratches come in contact with infectious body fluids from an HBV-infected person. HBV remains infectious for at least seven days outside the body and can be found on and spread through sharing of inanimate objects such as washcloths or toothbrushes.
Third, long-term protection following infant vaccination is expected to last for decades and will ultimately protect against acquiring infection at any age.
HBV can be transmitted in many ways in addition to sex contact and injection drug use. On average, an unvaccinated baby born in the United States has 5 out of 100 chances of developing HBV infection sometime during his or her lifetime. By avoiding obvious means of exposure, people can reduce their odds of becoming infected. But while there are degrees of risk involved in contracting HBV infection, there is no such thing as "no risk." Moreover, hepatitis B vaccine is the first vaccine to prevent cancer--HBV-related liver cancer.
At the present time, booster doses are not recommended routinely for people with normal immune systems. Although the level of protective antibodies in the blood of a vaccinated person seems to decline with time, the immune system retains an immunization "memory" and if the person is exposed to HBV, the system "kicks in" and provides the needed protection.
Experts are continuing to monitor the long-term effectiveness of hepatitis B vaccine and will issue recommendations on the need for booster doses if evidence shows that booster doses are necessary.
Blood testing before vaccination is not recommended for the routine vaccination of infants, children, and adolescents. However, certain children, such as those born in countries where HBV is moderate or highly endemic (see www.cdc.gov/ncidod/diseases/hepatitis/b/country_listing.htm for a list of these countries), should be tested to be sure they are not already infected. Testing can be done at the same visit when the first dose of hepatitis B vaccine is given. Vaccinating a person already immune to or infected with HBV will not help or harm the person.
The main reason for testing people at increased risk for HBV is to determine if they are infected. If after testing they are found to be infected, they must be referred to a health professional for ongoing medical care for chronic HBV infection.
Testing after vaccination is not recommended routinely. Testing after vaccination is recommended only for people whose medical care depends on knowledge of their response to the vaccine. This includes infants born to HBV-infected mothers; healthcare and public safety workers at risk of continued exposure to blood on the job; immune compromised people (e.g., people with AIDS or on hemodialysis); and sex and needle-sharing partners of people with chronic HBV infection. Testing for babies born to HBV-infected mothers should be done after completion of at least 3 doses of a licensed hepatitis B vaccine series, at age 9-18 months (generally at the next well-child visit). Testing for other persons should be performed 1-2 months after the last dose of vaccine.
No, the series does not need to be restarted. If the series is interrupted after the first dose, the second dose should be given as soon as possible; the second and third doses should be separated by an interval of at least 8 weeks. If only the third dose is delayed, it should be administered as soon as possible.
The minimum recommended dosing intervals are 4 weeks between the first and second doses and 8 weeks between the second and third doses. The minimum interval between the first and third doses is 16 weeks.
People who had a serious allergic reaction to one dose of hepatitis B vaccine should not have another dose of hepatitis B vaccine. People with a history of hypersensitivity to yeast should not receive this vaccine. People with a moderate or severe acute illness should postpone receiving the vaccine until their condition is improved.

Pelvic inflammatory disease or PID is a serious infection of the fallopian tubes and uterus. This infection, which may result in blockage or scarring of the tubes, is the most common preventable cause of infertility in women. It is estimated that over one million women in the U.S.
A condom (rubber, prophylactic) is a sheath worn over the penis. Condoms originally were designed to block the escape of sperm, but now have been shown to be effective in blocking entry and exit of bacteria and some viruses. Most condoms are made of latex but some, called "skin condoms," are made of sheep intestine. Only the latex condom should be used for disease protection because the AIDS virus, and possibly other disease agents, are able to penetrate the larger pores in the skin condom.
Vaginal spermicides are products such as foam, jelly, cream, suppositories or film that are inserted deep into the vagina on or near the cervix shortly before sexual intercourse. Most of these products contain nonoxynol-9, a chemical that kills sperm on contact. To be effective, a spermicide must be used every time intercourse occurs.
We recommend that vaginal spermicides always be used with condoms.
Emergency contraception (also known as EC or the morning after pill) works to prevent pregnancy in the case of unprotected intercourse. For maximum effectiveness, EC should be taken as soon as possible after unprotected sex. However, EC may be taken within 72 hours (3 days) of unprotected intercourse.
Ortho Evra or "the patch" is a birth-control patch. It contains the hormones norelgestromin and ethinyl estradiol, hormones similar to those used in birth control pills. Each contraceptive patch, which is thin, beige, flexible, and square, is worn on the body for 1 week at a time.
Once applied to the body, the hormones are absorbed through the skin into the blood stream. Like the birth control pill, the patch works by suppressing ovulation. It also causes changes to the cervical mucus and to the endometrium (lining of the uterus) that further reduce the chances of becoming pregnant.
Like the pill, the contraceptive patch is 99% effective when used correctly.
You may apply your first patch during the first 24 hours of your menstrual period. No back-up birth control method is needed.
Or you may wait until the first Sunday after your period begins. A non-hormonal method of birth control (such as condoms or a diaphragm) is needed for the first 7 days.
You can apply the patch to your abdomen, buttock, upper outer arm, or upper torso (but not the breasts). You can wear it in the same location each week. However, you should apply each new patch to a new spot on the skin. To ensure effectiveness, you should not write on the patch or alter it in any way.
You should apply the patch to clean, dry skin with no redness, irritation, or cuts. To make sure that the patch sticks properly, you should avoid using creams, lotions, oils, powder, or makeup on or near the site where the patch is to be applied.
Please refer to the patient package insert for specific instructions in applying the patch.
Check the contraceptive patch every day to make sure that it is still sticking firmly.
To remove a used patch, simply lift one corner and quickly peel back. Because a used patch still contains some active hormones, you should fold the patch in half so that it sticks to itself before you throw it away. If a small ring of adhesive is left on your skin (which may occur if certain clothing has rubbed against the patch), you can remove it by rubbing a small amount of baby oil on the area.
Yes. There is no need to alter daily activities while using the patch. Bathing, showering, swimming, exercising, or moisture due to wet or humid weather should not affect your contraceptive patch.
Yes. If you wish to alter the Patch Change Day, follow these instructions:
Except for possible minor skin reactions when the patch is placed, adverse events are similar to those associated with oral contraceptives. The most common side effects are breast symptoms, headache, application-site reactions, nausea, cramps, and abdominal pain. The patch is not associated with significant changes in weight.
The patch contains hormones similar to those in birth-control pills. Most side effects associated with the patch are not serious, and those that are serious occur infrequently. Serious risks, which can be life–threatening, include blood clots, stroke, and heart attack, and are increased if you smoke cigarettes. Cigarette smoking increases the risk of serious cardiovascular side effects, especially if you are older than 35 years. Women who use hormonal contraceptives are strongly advised not to smoke. Some women should not use the patch, including those who have had blood clots (this does not mean blood clots in your menstrual flow), certain cancers, or a history of heart attack or stroke, as well as those who are or may become pregnant.
In November 2005, Ortho Women’s Health updated the information it provides to clinicians and patients. The current patient information/warning states: “Hormones from patches applied to the skin get into the blood stream and are removed from the body differently than hormones from birth control pills taken by mouth. You will be exposed to about 60% more estrogen if you use ORTHO EVRA than if you use a typical birth control pill containing 35 micrograms of estrogen. In general increased estrogen exposure may increase the risk of side effects. However, it is not known if there are differences in the risk of serious side effects based on the differences between ORTHO EVRA and a birth control pill containing 35 micrograms of estrogen.”
NOTE: The patch does not protect against HIV infection or AIDS or other sexually transmitted diseases.
Call the clinic immediately or consult your private doctor or local Emergency Room if you experience ANY of the following:
These symptoms may be warning signs of a blood clot, heart attack or stroke.
There are some drugs that may interact with Ortho Evra (and other hormonal birth control methods) possibly making the birth control method less effective in preventing pregnancy or causing an increase in breakthrough bleeding. If you are ill or need medical care, tell your health care practitioner that you are using Ortho Evra. If surgery is anticipated, it may be advisable to discontinue Ortho Evra one month before the surgery. Please discuss this with your surgeon and clinician.
Please note also that women who are using a hormonal method of birth control and also use some form of St. John’s Wort have reported pregnancies and breakthrough bleeding.
The contraceptive patch is a reversible form of birth control. As with other forms of hormonal contraception, you may experience a delay in becoming pregnant after you stop using the patch, especially if you had irregular menstrual cycles before you used it. Your clinician may advise you to postpone trying to get pregnant until you begin menstruating regularly on your own.
Be sure you have available at all times a non-hormonal method of birth control such as condoms, diaphragm or spermicides.
If you do not know what to do about mistakes in using your patch, use a backup birth control method every time you have sex and contact your health care provider.
Individual replacement patches are available from your pharmacist.

Genital herpes is caused by the herpes simplex virus (abbreviated as HSV). It is very common--about 1 in 4 women and 1 in 8 men have genital herpes. There are two types of the virus:
A urinary tract (UTI) or bladder infection occurs when bacteria gain access to and multiply in the bladder. Bacteria infect the bladder by way of the urethra, a small, short tube that opens near the vagina. The placement and size of the urethra make bladder infections very common in women. Men rarely develop bladder infections because their urethras are longer.
