This is a transmission electron microscopic (TEM) image of Zika virus, grown in LLC-MK2 culture cells, which is a member of the family Flaviviridae. Virus particles are 40 nm in diameter, with an outer envelope, and an inner dense core. Also note the smooth membrane vesicles, which are known to be the replication complex for this virus.
“Zika virus is spread to people through mosquito bites. The most common symptoms of Zika virus disease are fever, rash, joint pain, and conjunctivitis (red eyes). The illness is usually mild with symptoms lasting from several days to a week. Zika virus can be passed from a pregnant woman to her fetus. Infection during pregnancy can cause certain birth defects.”
