ARI stands for Acute Respiratory Infection. Acute respiratory infection is a serious infection that prevents normal breathing function. It usually begins as a viral infection in the nose, trachea (windpipe), or lungs. If the infection is not treated, it can spread to the entire respiratory system.

Also, acute respiratory infections are infectious, which means they can spread from one person to another. The disease is quite widespread. It is dangerous for children, older adults, and people with immune system disorders. According to the World Health Organization (WHO), acute respiratory infections kill about 2.6 million children annually every year worldwide.

Other symptoms include congestion, either in the nasal sinuses or lungs, runny nose, cough, sore throat, body aches and, fatigue. If the disease advances, there may be a high fever and chills.
