Angola: Marburg haemorrhagic fever [update-4]

The outbreak of Marburg haemorrhagic fever continued unabated in Angola. As of 14 April, a total of 207 deaths from 224 cases were reported. About 80% of the cases were reported in the Uige province, where the outbreak was thought to have originated, the other affected provinces include the capital Luanda, Cabinda, Malange, Zaire, Kuanza Norte and Kuanza Sul.



Zambia issued health alert against Marburg haemorrhagic fever in provinces bordering with Angola: Northwest, West, and South.



All currently available data indicate that casual contact plays no role in the spread of the disease. WHO does not recommend restrictions on travel to any destination within Angola, but does advise some precautions. Travellers to Angola should be aware of the outbreak of Marburg haemorrhagic fever and of the need to avoid close contact with ill persons. Persons with existing medical conditions who might require hospitalization should consider deferring non-essential travel to Angola.



WHO recommends that travellers with a clear exposure history be treated as contacts and placed under surveillance for 21 days, during which time their temperature should be monitored daily.

Asia: Avian influenza [update-33]

Avian influenza continued to affect Asian countries, a total of 80 cases with 51 deaths were reported in Asia since the outbreak of avian influenza in late 2003.



Vietnam was seriously affected with more cases being reported. The latest victim was infected by both the HIV and avian influenza virus. She lived in the northern Quang Ninh province which was one of the provinces with highest numbers of HIV carriers. In southern Mekong Delta, initial testing showed that 70% of ducks were infected with avian influenza virus H5 strain. As many ducks are raised in fields and canals in the delta, the practice can spread the disease from province to province.



In Cambodia, the Ministry of Health confirmed that the recent fatal case in Kampot province was the third case of avian influenza. No poultry deaths occurred in the village in the two weeks prior to the girl’s onset of symptoms. Human-to-human transmission as a source of the girl’s infection appeared unlikely, as none of her known contacts were sick with similar symptoms before she became ill.



According to news report, millions of fighting cocks are raised in Thailand and infected cocks may have caused at least 8 confirmed human cases of avian influenza.



In Taiwan, H7N3 avian influenza virus was first detected in migratory birds in Guandu nature park. However, the virus does not affect human nor birds.
