What is a viral infection?
A viral infection is any disease caused by a virus. The most common viral diseases are: cold, flu, coronavirus, stomach flu, warts, herpes.
Many viral infections clear up within a few days, but some are chronic and some are life-threatening.
In a large percentage of clinical cases, viral infection causes diseases of the respiratory and digestive system, but it is quite possible to infect other parts of the body.
A virus and a bacterium show the same symptoms (in most cases), therefore, only a doctor and based on the appropriate laboratory analysis can identify what type of infection you are dealing with. If the symptoms do not improve in a few days, it is necessary to consult a doctor.

- People over 65 years old;
- Chronic disease in the anamnesis;
- Weak immunity;
- Pregnant women.

- Upper respiratory symptoms (sneezing, coughing, sore throat);
- Digestive system problems (nausea, vomiting, diarrhea);
- Skin problems (rash, warts, ulcers, old people).
