The Virulent Factors of Bordetella Pertusis: The Whooping Cough

Despite large-scale vaccination and management strategies, pertussis continues to be a global public health problem worldwide (Cherry J. D Heininger, 2004). Diseases in adolescents and adults are dramatically increasing, so they infect the baby. The reasons for the increase are as follows: reduced vaccine-induced immunity, increased recognition rate, changes in circulating strains, and improved methods for disease monitoring and diagnosis. However, due to the increase in the number of cases of pertussis during adolescence and adulthood, a reduction in immunity is causing a major public health problem.

Pertussis is an unpleasant disease caused by Bordetella pertussis and its unique cough is characterized. When I say "unique", I really mean a very annoying thing. The problem is to make the cell - free vaccine safer - your body rarely reacts to it much - it also means that it does not provide the same level of immunity as cellular vaccines. Even with a single administration of pertussis vaccine, a really excellent disease prevention effect can be obtained, but the defense level will start to decline in 8 to 10 years.

Pertussis or whooping cough is a highly infectious aerial bacterial disease caused by Bordetella pertussis. People may get sick by coughing or sneezing. About 16 million people worldwide are infected with this disease every year. The number of deaths from this disease decreased from 138,000 in 1990 to 60,000 in 2013. Mumps or mumps are viral diseases caused by mumps virus. It is highly contagious and the virus diffuses by touching the respiratory secretions of infected people. It may be transmitted from people to people by coughing or laughing. People infected with the virus may spread the disease to healthy people about three days before the onset of the symptoms and about 5 days after the swelling of the salivary glands. The mortality rate of mumps is low, the total mortality rate is 1 in 10,000 cases.

"Pertussis" also called "pertussis" is caused by Bordetella pertussis infection. It is a highly contagious bacterial disease that affects the respiratory system, usually resulting in a cough that ends in treble arse voices. In this report, we will explain the expansion, contraction of pertussis, available therapies, and patient prognosis. I will also tell you a lot of the symptoms of this disease. Pertussis is caused by Bordetella pertussis that invades the nose and throat, then the trachea, and the bronchi of the lungs. When an infected person coughs or sneezes, people usually infect bacteria via air. People then inhale or come into contact with infected saliva. Those who have been vaccinated in the past may still be infected, but they are usually heteromorphic or very mild and this is the cause of whooping cough. The incubation period is usually about 7 days.
