Sammanfattning
Zika virus is a mosquito-borne flavivirus transmitted by Aedes mosquitos. The virus was discovered in 1947 in the Zika forest in Uganda. Symptomatic disease
is usually mild and is characterized by maculopapular rash, headache, fever, arthralgia and conjunctivitis. Fatalities are rare. There is neither vaccine nor curative
treatment available. In May 2015, the first observation of local virus transmission was reported from Brazil. During the expanding outbreak in the Americas, Zika virus
infection has been associated with microcephaly in newborn and fetal losses in women infected with Zika virus during pregnancy. The main reason for the current
epidemic in the Americas is the introduction of an Old World virus into a new ecosystem, with no background herd immunity in the population. It is likely that the
spread of Zika virus will continue, affecting all countries in the Americas except for Chile and Canada.
