Our guide to the Zika virus
Friday, July 15th, 2016
What is Zika virus?
Zika is a mosquito-borne infection. It was first isolated from a monkey in the Zika forest in Uganda in 1947. It belongs to a family of viruses called flaviviruses.
Which countries are affected?
In May 2015, the first locally-acquired confirmed case of Zika infection was reported in north east Brazil and as of 25th January 2016, most states across Brazil have reported locally-acquired cases. Between November 2015 and January 2016, local transmission of the virus was detected in many new countries and territories.
The European Centre for Diseases Control provides an updated list of affected countries: http://ecdc.europa.eu/en/ healthtopics/zika_virus_infection/zika-outbreak/Pages/Zika-countries-with-transmission.aspx
Further cases of Zika are expected to be reported in other countries, particularly in the Americas, where the mosquito vector is present.
How serious is it?
For the vast majority of people, Zika virus infection causes a very mild disease. Serious complications and deaths from Zika are not common. However, recent increases in congenital anomalies (particularly Microcephaly), Guillain-Barré syndrome, and other neurological and autoimmune syndromes are being reported in areas where active Zika transmission is ongoing. The association of these illnesses with Zika virus is not yet proven and investigations in affected countries are ongoing.
How real of a problem is Zika?
We recognise the risks that Zika poses, in particular in relation to unborn children. There may be no symptoms, or these may be mild so a person would not know that they have the virus and may then either fall pregnant themselves or may pass this on to their partner who may then fall pregnant. Where a baby is born with Microcephaly this is a serious situation, it can result in numerous development problems that are likely to have an impact on the child and the family for life.
What should I do if I’ve recently been to an affected country and suspect I have the virus?
The symptoms of Zika virus are similar to other mosquito-borne infections such as dengue, chikungunya and malaria, so laboratory testing is essential for the correct diagnosis. If you have recently returned from an area where Zika virus is currently reported and have a fever or flu-like illness, seek medical attention without delay to exclude Zika and other, more serious, mosquito-borne diseases such as malaria. Please mention your travel history.
