Viruses Facts for Kids Fact Number 1: What Are Viruses?

Viruses Facts for Kids Fact Number 4: How Can We Treat Viruses?

Viruses cannot be treated with antibiotics, as antibiotics only work on bacteria. Antiviral medications can be used to treat some viral infections, but not all viruses can be treated in this way.

Viruses Facts for Kids Fact Number 5: How Do Vaccines Work?

Vaccines can help protect against some viral infections, by teaching the body how to recognize and fight the virus. A vaccine works by introducing a small, harmless part of the virus into the body, which triggers the immune system to create a response. This response helps the body to recognize and fight the virus if it’s encountered again in the future. Not all viruses have vaccines, but scientists are always working on developing new vaccines to protect against different types of viruses.
