An eating disorder is a medical illness caused by a disturbance in eating or exercising habits or body image that negatively affects a person's overall health. Eating disorders are often characterized by severely limiting food intake or excessive overeating. Sometimes exercise, vomiting, laxatives, or diuretics are used to eliminate food and calories from the body after an individual has eaten, or binged. A
Understanding the barriers to parent-college student communication is a critical step toward providing practical support for college students.
Whooping cough is a very contagious cough illness. It is spread through droplets from the mouth and nose when a person with pertussis coughs, sneezes, or talks. Young infants are at highest risk for severe illness, hospitalization and death from whooping cough.
Child passenger safety has dramatically evolved over the past decade; however, motor vehicle crashes continue to be the leading cause of death of children 4 years and older. This policy statement provides 4 evidence-based recommendations for best practices in the choice of a child restraint system to optimize safety in passenger vehicles for children from birth through adolescence:
Rubella is caused by a virus.
Rubella spreads from person to person through the air. Rubella is contagious but less so than measles and chickenpox.
The incubation period varies from 12 to 23 days (average, 14 days). Symptoms are often mild and may be inapparent up to half of the time.
Rotavirus disease is caused by a virus, the rotavirus. The name rotavirus is derived from the Latin rota, meaning "wheel," because the rotavirus has a wheel-like appearance when viewed by an electron microscope.
Polio is caused by a virus.
Polio is usually spread via the fecal-oral route (i.e., the virus is transmitted from the stool of an infected person to the mouth of another person from contaminated hands or such objects as eating utensils). Some cases may be spread directly via an oral to oral route.
The incubation period of polio is commonly 6-20 days, with a range of 3-35 days.
Pneumococcal disease is caused by Streptococcus pneumoniae, a bacterium. There are more than 90 subtypes. Most subtypes can cause disease, but only a few produce the majority of invasive pneumococcal infections. The 10 most common subtypes cause 62% of invasive disease worldwide.
Pertussis is caused by a bacterium, Bordetella pertussis.
Pertussis is spread through the air by infectious droplets and is highly contagious.
The incubation period of pertussis is commonly seven to 10 days, with a range of 5-21 days.
Pertussis disease can be divided into three stages:
Meningococcal disease is caused by the bacterium Neisseria meningitidis. This bacterium has at least 13 different subtypes. Five of these subtypes, A, B, C, Y, and W-135, cause almost all invasive disease. The relative importance of these five subgroups depends on geographic location and other factors.
