A three-year-old girl from Ferozepur died due to diphtheria in October. The health authorities and the World Health Organisation (WHO) mobilised a team on Sunday to contain the outbreak. The girl is from local Awa Basti, and has prompted immediate action from the health. The authorities informed that she was from a migrant family and had an unimmunised health background. she was brought in local civil hospital and was referred to Guru Gobind Singh Medical College and Hospital. To prevent any such cases, a vaccination drive has been initiated.What Is Diphtheria?As per WHO, Diphtheria is a disease caused by a bacterium that affects the upper respiratory tract and less often the skin. It also produces a toxin that damages the heart and the nerve. While it is a vaccine-preventable disease, multiple doses are needed to produce and sustain immunity.Those who are not immunised are at the risk of disease. WHO also mentions that diphtheria can be fatal in 30% of cases, with young children at higher risk of dying, if they are unvaccinated and are not receiving proper treatment. In 2023, an estimated 84% of children worldwide received the recommended 3 doses of diphtheria-containing vaccine during infancy, leaving 16% with no or incomplete coverage. What Role Did Covid Play?WHO mentions that the routine immunisation services and surveillance activities were affected during the Covid-19. This is why many children were susceptible to vaccine preventable diseases such as diphtheria. Signs And SymptomsWithin 2 to 5 days after exposure to the bacteria. The symptoms include a sore throat, fever, swollen neck glands and weakness. The dead tissue in the respiratory tracts forms a thick, grey coating that can cover tissues in the nose, tonsils, and throat, which makes it difficult to breathe and swallow. Severe cases happen as a result of the diphtheria toxin and its effects. TreatmentIt is usually treated with diphtheria antitoxin and well as antibiotics. Antitoxin neutralises circulation toxin in the blood. Antibiotics stop bacterial replication and thereby toxin production, speed up getting rid of the bacteria and prevents transmission to others. PreventionIt can be prevented by vaccines, and routine immunisation. The vaccine is given most often combined with vaccines for diseases such as tetanus, pertussis, Hemophilus influenzae, hepatitis B and inactivated polio.
