The differences between COVID-19 with different forms of severity of the disease are described. Writes about this “Parlamentskaya Gazeta”.
So, with a mild form of COVID-19, improvement occurs a few days after the first signs appear. This is due to the activation of the immune system, which begins to fight the pathogen. In this case, the general condition of the patient improves on the 5-6th day, but the fever and lack of smell may persist for some time. Full recovery occurs on the 10-14th day.
With an average severity of the disease, instead of improving, the patient may develop shortness of breath, chest tightness and severe weakness, and during this period the temperature rises strongly. It was during this period, the newspaper notes, that you should consult a doctor, since these signs may indicate lung damage. When treatment is started on time, improvement occurs on the 12-14th day, and for full recovery it may take up to a month.
The severe form of the disease is characterized by the development in the patient of such complications as acute respiratory distress syndrome – respiratory failure, accompanied by the development of pulmonary edema. This complication can also affect other organs. In this case, it is necessary to connect the patient to mechanical ventilation, and it may take up to two months before recovery.
Earlier, Rospotrebnadzor called the peak infectivity of the coronavirus, when an infected person is most dangerous to others. Natalya Pshenichnaya, Deputy Director for Clinical and Analytical Work of the Central Research Institute of Epidemiology of Rospotrebnadzor, noted that the highest level of COVID-19 excretion can be 2-3 days before the first symptoms appear. In particular, before coughing, runny nose, fever, or loss of smell. Pshenichnaya noted that even those who carry the infection in a mild form will be contagious at this point.
Those with COVID-19 are also dangerous during the first week after infection. Later, the viable virus becomes less active, but still persists in the human body, the expert added. If the disease is mild, then SARS-CoV-2 remains up to 10 days, if it is moderate-severe and severe, up to 20 days.
