As per recent reports by United Nations Organization's health agency, the number of people suffering from viral infection called yellow fever is on rise.

The World Health Organization (WHO) report asserted that Darfur, which falls in Western Sudan, is experiencing the highest number of viral infections and deaths from the same. Some 732 cases have been reported earlier this week in Darfur.

Out of 64 localities in the city, 33 have reported large number of cases with 165 deaths occurring due to the deadly disease. Recently, another 40 new cases have been discovered using IgM ELISA and PCR techniques by the National Public Health Laboratory in Khartoum in collaboration with NAMRU-3.

The figures were revealed in the report by a Global Alert and Response December 6 carried out by the WHO. Some 200,000 cases of yellow fever are recorded annually in the tropical areas of Africa and Latin America out which 30,000 end up in deaths.

The health agency said that the fever claims 50% of lives in the severe cases. There is no cure for the disease as of now. Treatment reduces the symptoms only while vaccination prevents the disease significantly.

Yellow fever is caused by infected mosquitoes and symptoms appear 5-6 days post-mosquito bite.
