Dengue fever is common and may be increasing in Southeast Asia.

Dengue fever is a flu-like illness spread by the bite of an infected mosquito. One major difference, however, is that malaria is often eradicated in major cities, whereas dengue is often found in urban areas of developed tropical nations, including singapore, taiwan, indonesia, and brazil. Caused by one of four closely related virus serotypes of the genus flavivirus, family flaviviridae, each serotype is sufficiently different that there is no cross-protection and epidemics caused by multiple serotypes can occur. Dengue is transmitted to humans by the Aedes aegypti mosquito, which feeds during the day. The mosquito flourishes during rainy seasons but can breed in water-filled flower pots, plastic bags, and cans year round. One mosquito bite can inflict the disease.

 Autoimmune hepatitis can produce after such viral infections as intense hepatitis A, hepatitis B or measles or after transmission with the Epstein-Barr virus.

Autoimmune hepatitis is a disease in which the system’s exempt structure attacks liver cells. Although the cause for this isn’t completely clear-cut, some diseases, toxins and drugs may spark autoimmune hepatitis in vulnerable folk, particularly women. The disease is normally rather severe and, if not treated, gets worse over moment. Usually, the exempt structure does not respond against the system’s own cells. However, sometimes it erroneously attacks the cells it is supposed to defend. This reaction is called autoimmunity. Some medications wound the liver immediately - overdoses of the popular pain backup acetaminophen, for instance, can induce liver bankruptcy. Other hereditary abnormalities may have autoimmune hepatitis more competitive and harder to handle.
