Symptoms of novel coronavirus infection include fever, dry cough, fatigue, decreased sense of smell and taste, poor breathing, diarrhea, conjunctivitis, headache, dizziness and chest pain.
The first day of onset: the symptoms are mild, and you may feel weak, with slight dry throat and sore throat.
The second day of onset: fever begins, and some young people will have a high fever of about 39℃, and the discomfort of the pharynx will be aggravated.
The third day of onset: the day with the most serious symptoms, the fever may be above 39℃, the whole body is weak and sore, and the sore throat is aggravated.
On the fourth day of onset: the peak temperature began to drop. Many people's body temperature has dropped to normal since this day, and they no longer have a fever. But it still hurts and itches, and some of them start to have a runny nose and cough.
The fifth day of onset: the body temperature basically dropped to normal. But it's still stuffy nose, runny nose, sore throat, cough and fatigue
The sixth day of onset: no more fever, cough and runny nose. This is because the provirus destroys the mucosa of our respiratory tract, and the human body has to expel dead cells through runny nose and cough. At this time, the virus may have been cleared and the nucleic acid may turn negative.
On the seventh day of onset: all symptoms began to improve obviously, and nucleic acid was likely to turn negative.
The above is the introduction of infection symptoms in COVID-19 now. I hope the above content will be helpful to everyone.
