According to the Centers for Disease Control and Prevention (CDC), Yellow fever virus is found in tropical and subtropical areas in South America and Africa. The virus is transmitted to people by the bite of an infected mosquito.

In Angola, the outbreak of the mosquito borne virus continues to grow as the latest reports show the case count has risen to 664 suspected cases, including 125 deaths since the first case was reported in Dec. 2015.

Of the deaths reported, 92 have been in the capital city of Luanda.

As the outbreak grows, the current government is receiving criticism of their reaction to the yellow fever situation. Eduardo Cuangana, with the country’s opposition Social Revival Party says the government should have acted earlier.

“It is a very worrisome situation. People in government could have taken care of it before it escalates. But they waited to the last moment to do the necessary: to use vaccines” he said.
