The Zika virus is a single-stranded RNA virus of the Flaviviridae family, genus Flavivirus. It is transmitted to humans primarily through the bite of an infected Aedes species mosquito. In this course, you will learn that the mosquito vectors typically breed in domestic water-holding containers, are aggressive daytime biters, and feed both indoors and outdoors near dwellings. You will also learn that non-human and human primates are likely the main reservoirs of the virus, and anthroponotic (human-to-vector-to-human) transmission occurs during outbreaks.

There is no vaccine to prevent infection or medicine to treat Zika. However, using insect repellent may help prevent one from being bitten by a carrier mosquito. This course will discuss the methods for the prevention of Zika, and also provide information about the disease for pregnant women. You will also learn that scientists are looking into the possible link between Zika virus infection and microcephaly, which is a condition where a baby’s head is much smaller than expected.

The World Health Organisation (WHO) has warned of the "explosive" spread in the number of Zika virus infections given the wide geographical distribution of the mosquito vector. This course covers key information about the disease and its health implications, especially in relation to pregnant women. So, have a look at this course today, and learn more about the disease and how to handle a potential outbreak in the future.
