Diphtheria is an acute infectious and toxic disease caused by diphtheria bacteria. The disease is common in young children, however, it can also occur in adults if they are not immune. The disease is easily transmitted through the respiratory tract or through direct contact with secretions from the nasal and throat mucosa of patients or healthy people carrying the virus when coughing or sneezing; especially in crowded residential areas or places with poor hygiene conditions.
Symptoms can range from mild to severe, with severe cases leading to complications and death. Previously, the disease was quite common in most localities across the country; since diphtheria vaccine was introduced into the expanded immunization program, the disease has been controlled and only a few sporadic cases have been recorded due to lack of vaccination, often occurring in remote areas with low vaccination rates.
