Corona Virus (Covid-19) Online MCQs Part 1

The virus that causes COVID-19 is in a family of viruses called Coronaviridae.
Antibiotics do not work against viruses.
These are MCQs on "Corona Virology" for Entrance examination like CBSE NEET etc.

1. Examples of DNA viruses include:

1. Coronaviruses.
2. Varicella zoster virus (VZV).
3. Respiratory syncytial virus (RSV).
4. Influenzavirus.
5. Cytomegalovirus (CMV).

2. How does Corona virus transmit?

1. When a person sneezes or cough, droplets spread in the air or fall on the ground and nearby surfaces.
2. If another person is nearby and inhales the droplets or touches these surfaces and further touches his face, eyes or mouth, he or she can get an infection.
3. If the distance is less than 1 meter from the infected person.
4. All the above are correct.




Coronavirus (COVID-19) transmits through the above-mentioned options.
