Key aspects of 36 mosquito-borne arboviruses indigenous to Africa are summarized, including lesser or poorly-known
viruses which, like Zika, may have the potential to escape current sylvatic cycling to achieve greater geographical
distribution and medical importance. Major vectors are indicated as well as reservoir hosts, where known. A series of
current and future risk factors is addressed. It is apparent that Africa has been the source of most of the major
mosquito-borne viruses of medical importance that currently constitute serious global public health threats, but
that there are several other viruses with potential for international challenge. The conclusion reached is that
increased human population growth in decades ahead coupled with increased international travel and trade is
likely to sustain and increase the threat of further geographical spread of current and new arboviral disease.http://www.parasitesandvectors.comam2018Medical VirologySchool of Health Systems and Public Health (SHSPH)Veterinary Tropical Disease
