Coronavirus is an acute viral disease, predominantly affecting the respiratory system.
The virus is transmitted by airborne droplets, airborne dust, and fecal-oral routes. Transmission factors include discharge of the nasopharynx, vomit, feces of birds, animals, and sick people.
In humans, the susceptibility to coronavirus is very high, all age groups are susceptible to the disease.
At the initial stage of infection with a new type of pathogen, the signs of coronavirus re very similar to all the signs of a common cold: dry cough, weakness, fever.
If the disease proceeds in a mild form, pneumonia does not develop and the entire pathological process is limited to mild symptoms. In such cases, the temperature may rise slightly or generally remain within the normal range.
In severe forms of the disease, the patient's condition rapidly worsens, a very high temperature rises, an unproductive persistent cough appears, and respiratory failure develops. The patient's condition worsens significantly in presence of concomitant diseases.
Diagnosis of coronavirus based on only clinical signs is impossible, since the symptoms of coronavirus are completely identical to the symptoms of other respiratory infections. Test systems can quickly determine the presence of coronavirus in the body.
