“Should we travel? Answering this question, Dr. Kang said that there is no need to stop movement in the country. Infection is very less in India. Travel, if you are worried. Wear mask if you are. Outside India, infection is high in some places, wear mask and travel. However they have advised not to travel to China for now. As government urged people to wear mask to stay safe Dr Kang said it is important to understand the purpose of wearing a mask. For a healthy person, masking is of little importance. But if you have a respiratory infection, stay at home. If you need to go out , then you use the mask.
