One way that COVID-19 is transmitted is through which of the following?

• A. Tears
• B. Urine specimens
• C. Semen
• D. Aerosol particles

Answer: (D)

The main concept is how COVID-19 spreads mainly through aerosol particles and respiratory droplets that are expelled when someone with the virus talks, breathes, coughs, or sneezes. Aerosols are small enough to stay suspended in the air for a while and can travel beyond close contact, especially in poorly ventilated indoor spaces. This is why measures like good ventilation and wearing masks help reduce transmission. The other fluids listed aren’t recognized as primary transmission routes for SARS-CoV-2 in typical settings, so tears, urine, and semen are not the main way the virus spreads.
