Dengue 3 virus transmission in Africa.

The first known transmission of dengue 3 virus in Africa was documented by virus isolation during an epidemic of dengue-like illness in Pemba, Mozambique, in late 1984 and early 1985. Dengue 3 virus was the only serotype isolated. Most patients appeared to be experiencing secondary flavivirus infections, but whether this was the result of previous dengue, yellow fever, or other flavivirus infection is not known. Two cases of hemorrhagic disease with shock and death were associated with the epidemic.
