Zika virus is primarily spread by Aedes mosquitoes (Aedes aegypti & Aedes albopictus). These also spread dengue & chikungunya. Infection occurs through mosquito bites during the first week of a person’s infection.
– Zika virus causes mild symptoms (fever, rash) but can lead to severe birth defects (e.g., microcephaly) during pregnancy.
– Aedes mosquitoes are most active during the day; use insect repellent & control breeding sites to prevent bites.
– Culex mosquitoes transmit West Nile virus.
– Anopheles mosquitoes transmit malaria.
