How To Identify Someone Affected By Covid 19?
Hello! Thank you for the question on HealthReplies.com
Symptoms caused by COVID-19 virus infection include symptoms of respiratory infections, such as coughing, runny nose, accompanied by fever, and in severe conditions can be found shortness of symptoms (if the infection has reached the lower respiratory tract).
For a definitive diagnosis, of course symptoms are not enough because there are many other causes of respiratory infections besides COVID-19, and the symptoms are similar and even the same.
Gold standard examination to detect for certain whether the cause of airway infection is caused by COVID-19, or the other is by Polymerase Chain Reaction (PCR) by detecting RNA virus COVID-19 taken from the throat swab.
To prevent infection and transmission of this disease, several things can be done:
Always make sure to wash your hands with soap or hand sanitizer before touching the face. Do social distancing, which is to avoid contact with others as much as possible, especially the crowd. Increase your body's resistance with adequate nutrition and fluids, and avoid stress. Use a mask when experiencing symptoms of channel infections. exhale as already mentioned above
That's all the explanation from me, hopefully it helps and useful :)
