infect

To infect something means to make it sick. When a person or animal is infected, they have a germ or virus inside them that is making them sick.

Germs and viruses can spread from person to person through things like coughing, sneezing, and sharing food or drinks. They can also spread through contact with animals or objects that are contaminated with germs.

Once a germ or virus gets into a person's body, it can start to multiply and make the person sick. The person's body will try to fight off the infection, but sometimes the infection can be too strong and the person will get sick.

The patient was infected with a deadly virus.
