Diseases & Conditions Facing the Survivors & Relief Efforts in Southeast Asia
On December 26, 2004 at 0058 hours GMT, a strong earthquake, which had a magnitude of 8.9 on the Richter Scale, occurred off the west coast of Northern Sumatra (Aceh). A subsequent tsunami has hit South and Southeast Asia causing serious damage and loss of life. Several countries bordering the Indian Ocean have been affected including Indonesia, Sri Lanka, Maldives, India, Thailand, Malaysia, Bangladesh, Burma (Myanmar), and Somalia. The WHO website contains information about the earthquake and subsequent tsunamis.
Travelers to affected regions should be aware of the situation. Natural disasters contribute to the transmission of some diseases, especially since water supplies and sewage systems have been disrupted. Outbreaks of food and water-borne diseases are possible such as diarrheal diseases, including dysentery and cholera. Other risks to travelers are typhoid and hepatitis A and E. When water and sewage systems have been disrupted, safe water and food supplies are of great importance in preventing enteric disease transmission.

Immediate health concerns
- After the rescue of survivors, the primary public health concerns are clean drinking water, food, shelter, and medical care for injuries.
- Flood waters can pose health risks such as contaminated water and food supplies.
- Loss of shelter leaves people vulnerable to insect exposure, heat, and other environmental hazards.
- The majority of deaths associated with tsunamis are related to drownings, but traumatic injuries are also a primary concern. Injuries such as broken limbs and head injuries are caused by the physical impact of people being washed into debris such as houses, trees, and other stationary items. As the water recedes, the strong suction of debris being pulled into large populated areas can further cause injuries and undermine buildings and services.
- Medical care is critical in areas where little medical care exists.
- Natural disasters do not necessarily cause an increase in infectious disease outbreaks. However, contaminated water and food supplies as well as the lack of shelter and medical care may have a secondary effect of worsening illnesses that already exist in the affected region.
- Decaying bodies create very little risk of major disease outbreaks.
- The people most at risk are those who handle the bodies or prepare them for burial.
The effects of a disaster last a long time. The greater need for financial and material assistance is in the months after a disaster, including
- surveying and monitoring for infectious and water- or insect-transmitted diseases;
- diverting medical supplies from nonaffected areas to meet the needs of the affected regions;
- restoring normal primary health services, water systems, housing, and employment; and
- assisting the community to recover mentally and socially when the crisis has subsided.
