Report on the situation of hand, foot and mouth disease (HFMD) in Thailand

Report on the situation of hand, foot and mouth disease (HFMD) in Thailand

By Department of Disease Control (DDC), Ministry of Public Health (MOPH)

31 July 2012

Thailand has conducted surveillance of HFMD, as a syndrome, since 2001. HFMD cases are reported by all hospitals and health centers in the public sector. During   2007-2011, annually 12,000 to 18,000 cases with 2-6 deaths were reported. 

Since 1 January until 21 July 2012, a total of 18,974 cases (case rate of 30 per 100,000 population) with 2 deaths of HFMD were reported from all 77 provinces. Male to female ratio of cases was 1.4: 1. More than 90 percent of the cases were under 5 years old, whereas 70 percent were under 2 years old.

The seasonal pattern of disease this year is similar to those of the previous years. The number of cases has been on the rise since June, see figure 1 below. Small clusters of cases were seen in kindergartens, elementary school as well as day care centers.

 Laboratory samples of HFMD cases tested by the Department of Medical Science, Ministry of Public Health, and by university laboratories have identified Coxsackievirus A and Enterovirus 71 (EV71) as main causes of infections.  

Of the two HFMD deaths, one was a girl 2 years and 8 months of age in Bangkok who had a history of frequent asthmatic attacks. She was admitted to a hospital in on 15 July, 3 days after the beginning of fever. She was found to have the inflammation of the heart and a respiratory failure, and died 2 days after hospitalization. Laboratory test identified EV71 of sub-genotype B5 from throat swab sample. Another one was a 2 years old Cambodian boy of a migrant worker family who had been living in Rayong province. He began to have fever on 21 July, 2012 and died on admission at a district hospital on 25 July. His throat swab sample was later found positive for EV71 of sub-genotype B5. In addition, a 16 years old boy in Sa-keo province died at a hospital on 3 July. He was diagnosed to have encephalitis, the inflammation of the brain, with failure of the heart and respiratory system.  His encephalitis was likely caused by EV71 as his throat swap sample was found positive for EV71 of sub-genotype B5.

 

MOPH has escalated surveillance and control of HFMD since early June 2012. The measures include:

·        Advice to Provincial Health Offices to intensify HFMD case detection and reporting, and to strengthen outbreak investigation and control by the surveillance and rapid response teams (SRRT).

·        Enhancing  risk communication through media and health volunteers stressing on personal hygiene (washing hands, and cleaning utensils and materials of common use) advice for sick children to stay home and seek medical care when having signs of severe illness.

·        Providing advice to day care centers, kindergartens and elementary schools to take cautionary and sanitation measures. These measures include: advising sick children to stay home; daily fever screening of children; cleaning utensils, toilets, toys and materials of common use by the children; and reporting the illness to local health authorities.  Day care centers and schools with clusters of HFMD cases are advised to consider temporary closure of affected class room or the school (for 5-7 days) and carry out proper cleaning; however, the decision should be made in consultation among teachers, parents and local health authorities.

·        Refreshing and supervision to medical personnel on guideline for management of severe HFMD cases with an emphasis on proper control of infection in health care facilities.

·        MOPH has not issued a travel advisory as it is considered not useful for prevention and control of HFMD. However, individuals who plan to travel to countries reporting HFMD outbreaks are advised to take hygienic measures (hand washing) and avoid taking children to public places or crowded areas to minimize risks of infection. Children who return from countries reporting HFMD outbreaks should seek medical care if they develop high fever or symptoms suspected of HFMD.
