Currently, right in this country of Vietnam, the situation of Covid-19 epidemic is increasing the number of infections. Doctors and nurses are trying to fight the epidemic in the most comfortable but very dangerous mood. Our people need to adhere to the following to repel the epidemic and contribute to reducing infections. 
\(-\) When we go out, we must always wear masks. Why? Because where masks can make we talk to another people and don't get sick. 
\(-\)Stand 2m away from others when shopping.
\(-\)If another people don't wear masks, you should remind them to wear mask. If you don't remind them, it will be more dangerous. 
\(-\)Do not congregate in crowded places
\(-\)When you go out and go back to your house, you need to wash your hands.
\(-\)Wear a mask, wear medical protective gear when in contact with people who have symptoms of flu, cough, runny nose, difficulty breathing, ...
\(-\)Wear everything that helps you not to let the virus spread and go to the hospital quickly if you have symptoms of Covid 19.
\(-\)Finally, comply with the 5K rule issued by the Ministry of Health
I believe that if everyone in this world works together to do these things, it will help fight the disease better and give the Ministry of Health more time to make vaccines and Covid 19 vaccines.
