What is ARVI?
Acute respiratory infections are a common name for a number of infectious diseases caused by viruses and bacteria and occur with symptoms of the mucous membranes of the respiratory tract (nose, larynx, trachea, bronchi), and sometimes with damage to the conjunctiva of the eyes.
Infection occurs from sick people. The main way of transmission of the virus is airborne, but it is also possible to get infected through household items (dishes, towels, toys, etc.), as well as when there are drops of the patient’s saliva when coughing or sneezing.
The incubation period takes an average of 2 to 7 days. The virus enters the mucous membranes of the upper respiratory tract with air flow and is introduced into the epithelium (cells of the outer layer of the mucous membrane), while endotoxin is released, which causes intoxication – poisoning of the body.
The main symptoms of the beginning of the disease include general malaise, weakness, nasal congestion, runny nose (rhinitis), coughing, lacrimation, sometimes headaches and fever. These symptoms may not appear at the same time and do not go away immediately.
