Question

alessandro is ill with a fever, a cough, and a runny nose. which precaution should he take to help his family avoid getting sick?
eat more vitamins
drink plenty of water
cover his mouth when coughing or sneezing
get extra rest when he feels tired or achy

Explanation:

When coughing or sneezing, covering the mouth helps prevent the spread of germs (such as viruses or bacteria that cause illness) through respiratory droplets. Eating more vitamins, drinking plenty of water, and getting extra rest are beneficial for the sick person's recovery but do not directly prevent family members from getting sick.

Answer:

cover his mouth when coughing or sneezing
