Uncovered coughing or sneezing and spitting in public also ___________.

• A. Increase immunity
• B. Purify air
• C. Sterilize surfaces
• D. Spread germs

Answer: (D)

Uncovered coughing or sneezing and spitting in public spreads germs because those actions release respiratory droplets that can carry pathogens. These droplets can travel a short distance and land on other people or contaminate surfaces and objects that others touch, creating opportunities for infection. This is why the correct idea is that it spreads germs. It doesn’t increase immunity—coughing or sneezing doesn’t boost your body's defenses. It doesn’t purify air—such actions contaminate air and surfaces rather than cleansing them. It doesn’t sterilize surfaces—uncovered coughing and spitting can introduce germs to surfaces. To reduce risk, cover coughs and sneezes with a tissue or inner elbow, wash or sanitize hands, avoid spitting, and regularly disinfect frequently touched areas.
