ARVI

ARVI (acute respiratory viral infection) is a group of infectious diseases caused by various viruses that affect the upper respiratory tract. These infections are most common in cold weather and are transmitted through airborne droplets or contact.

Causes and pathogens

• adenoviruses;
• rhinoviruses;
• coronaviruses;
• influenza viruses;
• parainfluenza viruses.

Infection most often occurs in crowded places such as schools, offices, and public transport, especially when immunity is lowered and the air is dry indoors.

Main symptoms

• runny nose and nasal congestion;
• cough, scratchy or sore throat;
• fever, chills;
• headache, body aches;
• weakness, fatigue, drowsiness.

Prevention

• wash hands regularly or use antiseptics;
• avoid contact with sick people;
• strengthen immunity through sleep, physical activity, and proper nutrition;
• ventilate and humidify the air indoors;
• if necessary, wear a mask in public places.

Treatment

• drink plenty of fluids to reduce intoxication;
• for high fever – antipyretics;
• medications for runny nose and cough as needed;
• rest and limit physical activity;
• plenty of warm drinks (broths, tea with lemon, soups).

In most cases, ARVI resolves on its own within 5-7 days.

If coughing worsens, breathing becomes difficult, or fever lasts more than 3 days, it is necessary to see a doctor – complications such as bronchitis or pneumonia may occur.

Conclusion

ARVI is one of the most common seasonal diseases. It is easier to prevent than to treat: maintain immunity, practice hygiene, and respond promptly to the first signs of infection.
