Sol. Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) is a highly contagious virus that spreads primarily through respiratory droplets. It belongs to the Coronaviridae family and is responsible for causing SARS, a severe respiratory illness characterized by fever, cough, shortness of breath, and pneumonia. The virus can also spread through surface contamination and close contact with infected individuals.

· (a) Ebola virus – Incorrect. Ebola virus spreads through direct contact with infected bodily fluids (blood, saliva, vomit, or sweat) rather than respiratory droplets.
· (b) Leptospirosis – Incorrect. Leptospirosis is a bacterial disease caused by Leptospira spp., transmitted through contaminated water or soil, not through respiratory droplets.
· (c) Hepatitis B – Incorrect. Hepatitis B virus (HBV) is transmitted through blood, sexual contact, and from mother to child during childbirth, not via airborne droplets.
· (d) SARS-CoV – Correct answer. SARS-CoV is a respiratory virus primarily spread through infected droplets released when an infected person coughs or sneezes.
