What causes pertussis

summary

Pertussis is a common disease for children, because children's resistance to the disease is relatively weak, many parents are also very worried about their children's physical problems, and pertussis this disease for children's multiple, so parents are particularly worried. Now let's talk about what causes pertussis.

What causes pertussis

First, acute respiratory infectious diseases caused by the source of infection. Pertussis patients, latent infection and carriers were the source of infection. From the end of incubation period to 6 weeks after the onset of the disease, the infectivity was the strongest in the first week of the disease.

Second, it is mainly transmitted by droplets. Pertussis toxin can mobilize lymphocytes from patients' lymphoid tissue to the surrounding blood and trachea when the bacteria are immersed in the respiratory tract of susceptible patients with air droplets. The cytotoxin can specifically damage the tracheal ciliated epithelial cells, causing degeneration and necrosis. Therefore, the prevalence of respiratory droplet transmission is very high.

Third, the population is generally susceptible, but the incidence rate of children is the highest. The mother does not have enough protective antibodies to the fetus, so the incidence of infants under 6 months is more. The disease may occur in four seasons, but mainly in winter and spring, children are prone to pneumonia and other complications, so new children should be treated in time under the guidance of doctors.

matters needing attention

After analyzing the causes of pertussis, I believe that parents have found some ways to prevent this acute respiratory infectious disease. For example, timely vaccination for children, as far as possible in the disease prone period to let children less contact with the outside world, and in terms of diet to be healthy and balanced measures.
