Which of the following is NOT an arboviral infection?
Select an option to attempt
Correct Answer: Option D
Explanation
Arboviruses (arthropod-borne viruses) are transmitted to vertebrate hosts via the bite of infected arthropod vectors (mosquitoes, ticks, sandflies): Dengue fever — Dengue virus (DENV 1–4, Flaviviridae), transmitted by Aedes aegypti and Ae. albopictus. Zika virus disease — Zika virus (Flaviviridae), transmitted by Aedes mosquitoes. Chikungunya fever — Chikungunya virus (Togaviridae, Alphavirus), transmitted by Aedes mosquitoes. COVID-19 — SARS-CoV-2 (Coronaviridae, Betacoronavirus), spreads via respiratory droplets, aerosols, and fomites. NO arthropod vector is involved in SARS-CoV-2 transmission. Therefore COVID-19 is NOT an arboviral infection.
