Yangcheng Evening News reporter Zhang Hua correspondent Pan Huiyi Wu Chanfeng.
Whooping cough, as the name suggests, has a long course of this cough. A series of coughs, coughing to vomiting, this may not be influenza A, influenza B, or even mycoplasma pneumonia, but whooping cough!According to the reporter's understanding, this is a highly contagious acute respiratory disease, and the characteristic clinical symptoms are paroxysmal spasmodic cough with inhalation "rooster crowing"-like echo, and the course of the disease is 2-3 months, so it is called whooping cough.
At present, the respiratory department and pediatric department of some hospitals have found that there is a trend of increasing number of children with whooping cough. Experts say the increase in these diseases may be related to immune evasion.
The baby, who was born less than a month ago, coughed and breathed like a rooster.
Xiao Tianbao, who was just 27 days old, suddenly had a cough. Xiao Tianbao was brought to the hospital by her family for treatment, and was diagnosed with whooping cough, and the child also had a variety of complications.
Why do babies at such a young age suffer from whooping cough?Peng Shumei, chief physician of the Department of Pediatrics of the Yuexiu Branch of Guangdong Provincial Maternal and Child Health Hospital, explained that this is a highly contagious respiratory disease that is easy to spread from person to person.
Chen Yunbin, chief physician of pediatrics at Guangdong Provincial Maternal and Child Health Hospital, described to reporters, "After the child has whooping cough, there is obvious paroxysmal spasmodic cough, which generally lasts for 2-6 weeks and can last for more than 2 months. A series of spastic coughs followed by a long, deep inhalation. As a large amount of air passes through the narrow glottis, it produces an inspiratory roar similar to a 'rooster'. This is followed by another cramp that repeats several times until a large amount of thick sputum is produced, accompanied by vomiting. Coughs are more severe at night, and the frequency and severity of coughs gradually increase. ”
It is understood that the younger the age, the more serious the condition of whooping cough, especially for babies under 6 months old, after a violent cough, due to the lack of time to inhale or the obstruction of sputum caused by suffocation, resulting in respiratory arrest, face, lips blue and purple. It can cause sudden infant death, complicated by pneumonia, epilepsy, encephalopathy, hernia, subdural hemorrhage, etc.
In the past, pertussis was mostly infants under 1 year of age, but now the age of children has been expanded to 6-10 years old. Tan Yanfang, deputy chief physician of the respiratory department of Guangdong Provincial Maternal and Child Health Hospital, said.
I have been vaccinated against diphtheria, why do I still get whooping cough?
The reporter inquired from the Guangdong Provincial Health Commission that the statistics on the incidence and death of notifiable infectious diseases in Guangdong Province in November last year showed that the number of pertussis cases in the province was 1,414 and the number of deaths was zero. This compares with 907 cases and zero deaths in October last year. A comparison of the two-month data shows that the incidence of whooping cough is on the rise.
Tan Yanfang, deputy chief physician of the respiratory department of Guangdong Provincial Maternal and Child Health Hospital, also told reporters that whooping cough has indeed increased in clinical practice.
Peng Shumei introduced that for whooping cough, macrolide antibiotics are usually needed to control infection, such as azithromycin, erythromycin, roxomycin or clarithromycin. Most infants under 4 months of age need to be hospitalized** because the infection is very severe and can be fatal in infants. Infants need to be closely observed and given oxygen, fluids, and nutritional support.
In the process, whooping cough will be more severe than other respiratory infections, but if you have been vaccinated, the cough symptoms may not be as severe, and the course of the disease will be longer. Chen Yunbin said.
In fact, most people have been vaccinated with DTP vaccine to prevent pertussis in childhood, and the current recommended vaccination time is 4 consecutive doses of DTP vaccine in March, April, May, and 18 months. However, infants may be infected with whooping cough before fully 4 doses, with the highest incidence in infants under 1 year of age. In addition, children, adolescents, and ** can also develop whooping cough if they were not vaccinated or received many years ago.
Some scholars believe that the recurrence of pertussis is also related to factors such as the mutation of strains, the low vaccine coverage rate caused by vaccine hesitancy, and the weak mucosal immunity of acellular pertussis vaccine.
