****A free service of the APEC Emerging Infections Network*****

The EINet listserv was created to foster discussion, networking, and collaboration in the area of emerging infectious diseases (EID's) among academicians, scientists, and policy makers in the Asia–Pacific region. We strongly encourage you to share their perspectives and experiences, as your participation directly contributes to the richness of the "electronic discussions" that occur. To respond to the listserv, use the reply function.


In this edition:

  1. Infectious disease information from ProMED and other sources
  2. Updates from previous bulletins
  3. Notices
  4. How to join the EINet listserv


1. OVERVIEW OF INFECTIOUS–DISEASE INFORMATION FROM PROMED  
Below is a bi–weekly summary of Asia–Pacific EID issues based on postings to the ProMED Electronic Network and other sources. ProMED is the prototype for a communications system that monitors emerging infectious diseases globally, an initiative of the Federation of American Scientists (FAS), and co–sponsored by WHO.

ASIA

SINGAPORE – HEPATITIS CONTROL
According to a report presented at the International Hepatitis Congress, the number of hepatitis cases in Singapore has fallen considerably during the past 15 years. Hepatitis B infections have dropped from 10 cases per 100,000 in 1985 to 4 cases per 100,000, and there have been no reports of hepatitis C since 1993. The majority of hepatitis A cases recorded have been acquired overseas.

Increased surveillance, infection–control precautions, blood donor screening, and public health education have contributed to Singapore's strategy to combat hepatitis infections.

SINGAPORE – MEDICAL EXAMS
In March, all expatriates and long–term visitors (>6 months) will be required to pass a medical examination before a permit is granted to live and/or work in Singapore. The exam – which will include a physical, a chest x–ray, and a HIV test – has been mandated to strengthen the control of communicable diseases like HIV and tuberculosis in the country. Those seeking renewals of passes will also be required pass a medical exam.

There are currently 80,000 employment pass holders and 450,000 work permit holders in Singapore.

MALARIA DRUG RESISTANCE
Scientists in Australia have found a mutation–prone gene that appears to play a significant role in drug resistance in the malaria parasite. Evidently, the mutations enable the organism to either block drugs from entering, or quickly pumping them out; as a result, anti–malaria drugs cannot accumulate within the parasite.

Resistance was demonstrated against the drugs, quinine, mefloquinine, and halofantrine; the gene also appears to influence resistance to chloroquine and artemisinin. The mutated gene was studied in Plasmodium falciparum, the deadliest strain of malaria.

Malaria kills more than a million people annually.

AMERICAS


MEXICO–MALARIA
A Pittsburgh resident is in critical condition with ARDS, renal failure, hemolysis, and hepatic dysfunction after travel to Cancun (and neighboring rural areas) on January 20, 2000. Plasmodium falciparum malaria was isolated in a peripheral blood smear by the hospital laboratory.

This report succeeds 2 cases of Plasmodium vivax recorded earlier this month; both presented malaria upon return from a vacation in Cancun. Each traveler responded to chloroquine therapy, and has since initiated terminal treatment with Primaquine. Rumors of additional malaria cases in the area have surfaced amid these reports. The origin of the cases has not been confirmed.

The U.S. Centers for Disease Control and Prevention (CDC) has recommended chloroquine prophylaxis to travelers to Cancun.

USA–CHICKEN NUGGETS RECALL
Over 114,000 pounds of chicken nuggets and patties have been recalled for fear of Listeria contamination. An investigation by the U.S. Agriculture Department was initiated after Listeria monocytogenes was found in an open package of chicken nuggets in Ohio. The meat was produced for schools in Maryland, Pennsylvania, Virginia, Texas, Colorado, and Ohio.

No reports of illness have been received to date. Listeria infection usually leads to high fever, severe headache, neck stiffness, and nausea.

USA–PNEUMOCOCCAL VACCINE
The U.S. Food and Drug Administration (FDA) has approved Prevnar (Wyeth Lederle Vaccines), the first vaccine to prevent invasive pneumococcal disease in infants and toddlers. The 4–shot series will be administered to infants at ages 2, 4, 6, and 12 to 15 months. The vaccine is estimated at $58/dose.

In clinical trials, Prevnar was 100% effective in preventing invasive pneumococcal disease caused by the most common 7 strains of pneumococcus; it was 90% effective in preventing invasive disease caused by all S. pneumoniae strains. The Advisory Committee on Immunization Policy at the U.S. Centers for Disease Control and Prevention has strongly recommended that all children <2 years of age are vaccinated, and has suggested that only high–risk children between the ages of 2 and 5 receive Prevnar.

An estimated 16,000 cases of pneumococcal bacteremia and 1,400 cases of pneumococcal meningitis occur in the U.S. annually.

CANADA–MENINGITIS
A $1 million immunization plan was launched in Edmonton last week in response to a meningitis outbreak. The vaccination effort targeted teenagers aged 15 to 19, and eventually expanded to include children between the ages of 2 and 15, upon parental request. The vaccinations were provided free of charge by the provincial government.

Meningitis has affected 22 Albertans, including 2 fatalities, since mid–December. In greater Edmonton, 15 people have been affected; 8 cases were between the ages of 15 and 19.

Meningitis, an inflammation of the membrane that lines the brain and spinal cord, and meningococcemia, a severe disease that targets the blood and other areas of the body, are spread through saliva, and present flu–like symptoms.

BREASTFEEDING AND INFANT MORTALITY
Data obtained from studies conducted in Pakistan, Brazil, Gambia, the Phillipines, Ghana, and Senegal, have revealed a lower mortality rate among breastfed children through the second year of life; however, the protection seemed to diminish with increasing child age. Infectious disease mortality appeared to decrease by as much as 6 times during the first few months among breastfed infants.

The protective effects of breastfeeding against infectious diseases remain an issue of debate among many policymakers, particularly, amid reports of mother–to–child transmission of HIVם through breastfeeding.

EL NINO INCREASES DIARRHEAL INCIDENCE
According to a study published in The Lancet, diarrheal disease admissions increased 200% during the 1997㫺 El Nino season. The increase was above the normal expected number, particularly during the winter months in Peru (May–November). Researchers estimated an increase of at least 8% in diarrheal admissions per every 1 degree (celcius) increment rise.

Diarrhea causes 1 billion episodes, and 3 million deaths annually in children <5 years of age.

GLOBAL HEALTH CONTROL MEASURES
During a forum sponsored by the Institute for Global Health, international health leaders proposed recommendations to address current global health issues. The participants comprised of representatives of the World Health Organization (WHO), World Trade Organization (WTO), the World Bank, Glaxo–Wellcome, and Chiron, to government officials from Indonesia, India, South Africa, the U.S., Canada, and Europe.

A number of measures were suggested to increase global health intervention by the private industry: providing tax credits on research, encouraging public–sector venture capitalist funds, harmonizing licensing and expediting drug and vaccine approval for diseases prevalent in developing nations. The responsibility of government was also addressed, specifically, to provide funding and incentive to ensure more equitable development and distribution of life–saving vaccine and drugs.

There is currently an estimated delay of 10 years between drug and vaccine development and the time prior to its delivery to developing countries.

HIV VACCINE INITIATIVE
The World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) have announced a new HIV vaccine initiative. The mission aims to increase international collaboration for vaccine development, with a particular focus on strengthening research in developing countries, where 95% of HIV infections occur.

Coordination for global health in HIV has become increasingly important with the emergence of multiple HIV subtypes and investigational vaccines.

2. UPDATES FROM PREVIOUS BULLETINS

RUSSIA–HEMORRHAGIC FEVER WITH RENAL SYNDROME
In January, over 200 cases of hemorrhagic fever were recorded in Tatarstan, a region 560 km northeast of Moscow. There were no fatalities. The epidemic has affected 39 districts in the republic to date.

Approximately 1300 cases of the fever were reported in the area last year.
[ITAR–TASS NEWS AGENCY 1/31/00]

MALAYSIA–NIPAH VIRUS
A patient hospitalized since April 1999 for Nipah encephalitis became the second fatality recorded from Nipah virus this year. Over 250 cases and 100 fatalities of encephalitis were reported between October 1998 and May 1999.

The recent fatalities have raised concern among those who are positive for the antibody; specifically, about the potential for infection to occur persistently and asymptomatically, thereby leading to symptoms months after primary infection. There is currently no evidence to support (or negate) this hypothesis.

3. NOTICES

APEC INDUSTRIAL SCIENCE AND TECHNOLOGY WORKING GROUP CONFERENCE
Emerging infectious diseases will be an important topic at the upcoming 18th Meeting of the APEC Industrial Science and Technology Working Group in Thailand (March 14㪩); two key discussions will take place.

One special meeting (8 am, 14 March) will bring together the economies involved in a project establishing a regional system to enhance collective capacity for emerging infectious disease surveillance and outbreak response. This project, approved at the 17th ISTWG in Seattle last August, is first focusing on a survey of health and other officials throughout the APEC economies. The survey will help define the current status of computer capability, facilities, staff, etc. needed for improved networking on infectious disease. Parties interested in attending this meeting must be delegates to the ISTWG, and request an invitation. Please contact the U.S. lead delegate on this project, Col. Patrick Kelley, for information (Patrick.kelley@na.amedd.army.mil).

A side meeting on Emerging Infectious Diseases and Environmental Health issues will occur at 13.30 hrs on 14 March. This meeting will focus on updates on health–related projects previously approved by ISTWG, as well as discussion about new proposals and future activities. Side Meetings in the past few years have been an important part of the progress made within APEC toward greater collaboration on health issues. The meeting will be chaired by Dr. Melinda Moore of the United States (mym5@cdc.gov).
