Whooping cough is an acute infectious disease, accompanied by inflammation in the upper respiratory tract and paroxysmal spasmodic cough.
Unvaccinated children under 5 years of age are most often infected, and whooping cough is especially dangerous for children in their first year of life. At an older age, this infection is much easier.
Whooping cough is caused by a specific bacterium called Bordetella pertussis. The microbe is transmitted by airborne droplets (by coughing, sneezing, talking) in close contact with a sick person. The disease is very contagious. However, a contact (for example, through toys) transmission of infection is impossible, since the bacterium quickly dies in the external environment.
Immunity after the disease is developed very persistent and usually lasts for life. Repeated diseases can occur in old age. However, as a rule, doctors take him for a cold – the disease is so easy. Continue reading
The likelihood of contracting a non-painful measles person in contact with a patient approaches 100%. Most often, children of preschool and school age are sick.
The source of infection is a sick person. The patient is contagious 4-6 days before the rash and in the first 4 days of the rash. The infection is transmitted by airborne droplets – by coughing, sneezing, talking and even breathing. A vertical transmission of measles is also possible – from a pregnant woman to the fetus.
The incubation period lasts an average of about 1-2 weeks.
Then the virus enters the blood from the mucous membrane of the mouth and pharynx and spreads to almost all organs and tissues. Continue reading
Mass vaccination against mumps has led to certain changes in the nature of the spread of this disease. If earlier they were mostly ill for children aged 3-6 years, then in recent decades there has been a significant “growing up” of infection. Children 3-6 years old get sick relatively rarely, but the incidence among schoolchildren has increased by 14 times. Now schoolchildren are almost two-thirds of all cases, and the remaining third are in adults. Moreover, among those who have previously been vaccinated for mumps, more severe forms of infection are recorded.
At the moment, more than 30% of the adult population does not have immunity against this “childhood” disease. Frequent outbreaks of infection in closed groups. In adults, the course of the disease is not very different from the classical form. The disease is characterized by an acute onset with an increase in body temperature to 38-40 ° C, with the appearance of signs of general intoxication, pulling pains and a feeling of tension in the parotid region, tinnitus, most patients have bilateral lesions of the parotid salivary glands. Within 4-5 days, the lesion reaches a maximum and disappears after another 7-10 days. Continue reading
