Does whooping cough last for 100 days?

Pertussis is an acute respiratory infectious disease caused by Bordetella pertussis, which has a long course of disease and typical symptoms can be manifested as a cough lasting 2-3 months,

so it is called "pertussis". Affected by the epidemic cycle, pertussis has an epidemic peak in about 3 to 5 years, and many countries or regions in the world are currently in the peak period of pertussis epidemic.

Who gets whooping cough?

Pertussis can strike people of all ages, but infants under 5 years of age who have not been vaccinated are most at risk. Before the widespread use of vaccines, pertussis was one of the most common childhood diseases and was a major cause of infant and child death worldwide.

How does whooping cough spread?

Pertussis is spread mainly by respiratory droplets, but also by close contact. Infected persons are the main source of infection, and for infants and young children, parents or other people who are infected with Bordetella pertussis are the main source of infection.

Families with infants under 1 year of age who have persistent cough in their family members should seek medical attention as soon as possible and avoid close contact with the infant.

What symptoms do you need to see a doctor in time?

Typical cases of pertussis can be manifested as upper respiratory tract infection symptoms 1-2 weeks later, there are spastic spasmodic cough, accompanied by chicken crowing sound, cough aggravated at night,

may be accompanied by vomiting. Among them, there is no typical spastic cough after infection in infant cases, prone to cyanosis, shortness of breath, apnea, and even asphyxia, and the above related symptoms should be checked in time to avoid delay in treatment.

Due to the relatively perfect immune function of adults, they often appear as intermittent cough and temporary relief after illness, but if they do not pay attention to isolation, it is easy to cause disease transmission.

Can pertussis vaccination provide lifelong immunity?

It is understood that vaccination against pertussis and natural infection with pertussis do not produce lifelong immunity, but vaccination is still the most economical and effective measure to prevent pertussis.

Since 1978, China has included the pertussis - diphtheria - tetanus combined vaccine, also known as DTP vaccine, in the immunization program. With the continuous improvement of the vaccination rate, the reported incidence of pertussis in China has decreased significantly,

and the risk of severe illness and death has decreased. Children between 3 months and 5 years of age are reminded to receive DTP vaccine as early as possible, and children of the appropriate age who are not fully vaccinated should be replaced as soon as possible.Prevent hand, foot and mouth disease, whooping cough...
