Small peak of respiratory diseases caused by multiple pathogens (theme)

Yangcheng Evening News reporter Zhang Hua

Cough, fever, diarrhea... Recently, there was another small peak of respiratory diseases. The reporter learned from several employers that the number of people who ask for leave due to illness has increased significantly recently. According to the statistics of the pediatrics outpatient clinic of Guangdong Maternal and Child Health Hospital (Yuexiu Hospital), the positive rate of mycoplasma among the patients is high, accounting for 30% to 40%, and about 20% of the patients are infected with A and B. The number of visits to pediatric clinics in Guangzhou Women and Children's Medical Center also increased significantly, with mycoplasma pneumoniae infection, influenza, pertussis, etc.

The number of paediatric out-patient clinics has soared, with mycoplasma positive accounting for 30% to 40%

"At first, she coughed, and now she has a fever." Miss Liu was pale and tired. She struggled to work in the company for half a day, so she hurriedly asked for leave and went home. She said that she coughed and had a fever on the 15th, and her condition fluctuated. On the 26th, she had a fever again. "She has been infected several times, and this time it seems very lingering".

Spring is a period of high incidence of respiratory diseases. According to the reporter's investigation, many employers have recently increased the number of employees who ask for leave due to illness, and the school has also issued a reminder: students should go home with fever and not take sick classes. Chen Yunbin, chief pediatrician of Guangdong Maternal and Child Health Hospital, told the reporter that there was a small peak of respiratory diseases at present. "Yuexiu Hospital has nearly 1000 outpatient and emergency paediatrics every day, and about 500 at ordinary times, double the number. According to the nucleic acid test of the pediatric outpatient clinic patients, the positive rate of mycoplasma is high, accounting for 30% - 40%, and about 20% of the A and B flows. Xinguan has no routine test."

"What kind of virus is the infection confirmed, and then the symptomatic treatment." Chen Yunbin said that during the treatment process, some patients have a tendency to abuse antiviral drugs, which not only can not play a substantive therapeutic role, but also may make the human body gradually resistant to such drugs. Once really needed to use, the effect may be greatly reduced.

Children also have a high incidence of whooping cough. Do not misuse drugs

The children's immune system is not fully developed, the climate becomes warmer in spring, allergens and dust increase, and it is easy to damage the respiratory tract mucosa; At the same time, strong winds and severe temperature changes are also conducive to the spread of the virus.

Yin Genquan, director of pediatrics at Guangzhou Women and Children's Medical Center, also revealed to the reporter that at present, there has been a wave of small peaks in pediatric outpatient visits, with mycoplasma infection, influenza, whooping cough and other common diseases, especially whooping cough. "We suggest that whooping cough should not be misused, but should still use macrolides, and compound sulfamethoxazole can be selected when drug resistance occurs."

It is understood that whooping cough is an acute respiratory infectious disease caused by Pertussis bacilli. The patients are mainly characterized by paroxysmal spasmodic cough, accompanied by deep "chicken crowing" like inspiratory roar. The course of disease is long, and untreated cough symptoms can last for 2-3 months, most of which are seen in children under 5 years old, with a high incidence of infants under 6 months old.

For pertussis, the immunization program for children under the national immunization program stipulates that children should be vaccinated against pertussis at the age of 3, 4, 5, and 18 months. Ingen Quan said that at present, the cell-free DPT joint vaccine is a national immunization program vaccine, which can be vaccinated free of charge; The quadruple vaccine and quintuple vaccine are non national immunization planning vaccines, and they are voluntarily vaccinated at their own expense. "It is suggested that the country introduce cell-free component purified vaccine (cell-free co purified vaccine is currently used) to play a better role in protection," said Yinganquan.

The new crown has not disappeared, and citizens have been infected for the third time

In spring, the weather is changeable, and the temperature difference between morning and evening is large, which makes people unable to adapt in time, reduces their immunity, and viruses enter through the void.

Ms. Chen, 40 years old, has recently been infected with COVID-19 for the third time. She went on a business trip for a period of time, and stayed up late without a good rest, so she was tired. A few days ago, she went to the hospital to visit friends many times, so she was recruited. "I have never measured such a clear 'yang' line. In addition to coughing and fever, diarrhea is also obvious."

Generally speaking, once infected with influenza virus, coronavirus or mycoplasma pneumoniae, fever, cough and other symptoms often accompany. Chen Yunbin pointed out that upper respiratory tract infections such as gastrointestinal colds, influenza, pneumonia, bronchitis caused by coxsackie virus infection can also cause diarrhea.

Still tired during recovery? Well, I have to keep it for a month

Many patients infected with influenza found that after taking antiviral drugs (such as oseltamivir) and symptomatic treatment to alleviate fever, muscle soreness and other discomfort, their symptoms improved significantly, and even the virus test had turned negative. However, for a period of time after recovery, they always felt tired and weak, and their mental state was not very good.

In this regard, Chen Yunbin explained: "The reason is that after the virus attacks the human body, the human body reacts to it and releases inflammatory mediators. While eliminating the virus, some internal organs are also damaged, and some toxins remain in the body, so people will feel tired and powerless."

But don't worry too much. Your body can recover. Chen Yunbin said that the premise is not to shoulder hard and pay attention to rest. "We found that some convalescents worked too hard, leading to repeated illness. During the recovery period, they should rest more, stay up less and work less overtime. The recovery period will take more than a month."
