Viruses test

Viruses are much smaller than cells. In fact, viruses are basically just capsules that contain genetic material. To reproduce, viruses invade cells in your body, hijacking the machinery that makes cells work. Host cells are often eventually destroyed during this process.

Viruses are responsible for causing many diseases, including:

• AIDS
• Common cold
• Ebola
• Genital herpes
• Influenza
• Measles
• Chickenpox and shingles
• Coronavirus disease 2019 (COVID-19)

Antibiotics designed for bacteria have no effect on viruses.
