Corona virus is a dangerous virus that does not appear for several days

Corona virus is a dangerous virus that does not appear for several days.
Now the question arises:
If a person gets this virus, how does he know that he has the Corona virus? Taiwanese doctors have introduced a simple test that you can do yourself.
In the morning, take a deep breath and stop inside and hold your breath for ten seconds.
In the meantime, if you do not have cough or shortness of breath, it means you do not have the virus.
Tell.
Do not let your throat and mouth dry at all for every fifteen minutes. Doing so will not prevent any virus in your mouth or throat, but will be digested through the gastrointestinal tract.
If you do not, the virus will enter the lungs through your respiratory tract please Forward most of your friends, dear friends, because Allah intends to save the life of one human being.
