Wellbeing A-Z -Viral infection

The video discusses the differences between bacterial and viral infections, highlighting how modern medicine uses antibiotics to combat bacteria, while viruses pose more complex challenges. It explains how viruses hide in human cells, making them difficult for the immune system to detect. Vaccinations help by giving the immune system a preview of the virus, but some viruses, like the common cold, mutate too quickly for vaccines to be effective. The video also emphasizes preventive measures like coughing into elbows and regular hand washing to slow virus spread.

What is a key difference between bacterial and viral infections in terms of treatment?

• Both bacteria and viruses can be treated with antibiotics.

• Bacteria can be treated with vaccines, while viruses cannot.

• Bacteria can be treated with antibiotics, while viruses require different approaches.

• Viruses can be treated with antibiotics, while bacteria cannot.

Why are viruses more challenging for the immune system to detect compared to bacteria?

• Viruses do not change the appearance of cells.

• Viruses are less complex than bacteria.

• Viruses hide inside human cells, making them less visible.

• Viruses are larger than bacteria.

How do vaccinations assist the immune system in combating viruses?

• They strengthen the body's lymphocytes to fight bacteria.

• They provide a preview of the virus, allowing the immune system to prepare.

• They introduce live viruses to the body.

• They eliminate the virus completely from the body.

What is a major challenge in developing vaccines for viruses like the common cold?

• The viruses mutate, changing their structure.

• The viruses are too large to study.

• The viruses are already eradicated.

• The viruses are not contagious enough.

What is a recommended practice to help prevent the spread of viruses?

• Cough and sneeze into your hands.

• Avoid washing hands regularly.

• Share personal items with others.

• Cough and sneeze into your elbow.
