Mycoplasma, COVID, influenza, adenovirus, ......, this autumn and winter, the hot search was swiped by various pathogens in turn. Recently, respiratory syncytial virus has rushed to the first place in the hot search on Weibo, and some netizens have asked, what kind of virus is this?We also quickly contacted a pediatric specialist, let's hear together.
Li Huiying, Director of the Comprehensive Pediatric Ward of Xuchang Central Hospital:
Syncytial virus is also a very common respiratory virus, and viruses are generally divided into DNA viruses and RNA viruses. This virus is an RNA virus, which can generally cause upper respiratory tract infections and lower respiratory tract infections. In fact, most babies before the age of two have basically been infected with this virus, but sometimes the symptoms are very mild, and parents sometimes do not realize that the virus is infected. The general season in the north is from October to May of the following year.
Director Li Huiying introduced that respiratory syncytial virus is mainly transmitted through droplets and close contact. The clinical manifestations of respiratory syncytial virus infection vary greatly, mild symptoms are like the common cold, with nasal congestion, runny nose, cough, hoarseness, low-grade fever and other manifestations, and a small number can develop into lower respiratory tract infection, that is, bronchiolitis or pneumonia, which mostly occurs in young infants, and the clinical symptoms include cough and wheezing.
Parents need to be reminded that infants, especially premature babies or infants aged 6 months and below, children with congenital heart disease or chronic lung disease, children with immunodeficiency or immunocompromised, and children with neuromuscular diseases, even if the symptoms are not severe, should be taken seriously, because they may turn into severe disease at any time. In addition to respiratory syncytial virus, which is a concern, the number of people infected with influenza virus has been increasing recently.
Li Huiying, Director of the Comprehensive Pediatric Ward of Xuchang Central Hospital:
In the previous period, mycoplasma infection was mainly prevalent, and now mycoplasma infection has a downward trend, but syncytial virus and influenza virus have an upward trend, and now the number of outpatient infections has increased significantly, and the number of hospitalized patients testing for syncytial virus is also increasing.
According to the observation at this stage, the number of influenza virus and syncytial virus infection may continue to increase, among which the lower respiratory tract infection caused by respiratory syncytial virus infection is mainly infants and young children, and the age span of influenza virus infection is large, so in addition to the symptoms after respiratory syncytial virus infection just introduced, everyone should also understand the symptoms after influenza virus infection.
Li Huiying, Director of the Comprehensive Pediatric Ward of Xuchang Central Hospital:
First of all, the simplest can do a routine blood test plus CRP examination, through the most basic examination, we can preliminarily determine whether it is a viral infection or a bacterial infection. If further tests are needed, we can check the antigen of influenza or the nucleic acid test of influenza to further rule out whether it is an infection of influenza virus.
For mycoplasma testing, if the child's disease course is less than one week, we first recommend him to do a nucleic acid test, which is a mycoplasma nucleic acid test, and if the disease course is more than one week, we recommend that he do a mycoplasma antibody test. In the case of syncytial virus, syncytial virus antigen or syncytial virus nucleic acid can also be checked, which are more recommended.
Season with high incidence of respiratory infections
Precautions need to be taken
As for how to prevent the epidemic, we specially consulted pediatric experts, and as far as the several pathogens currently circulating are concerned, only the influenza virus can be vaccinated. For high-risk groups such as children, the elderly, pregnant women, and those with underlying medical conditions, timely vaccination is very necessary.
Li Huiying, Director of the Comprehensive Pediatric Ward of Xuchang Central Hospital:
At present, there is no vaccine against syncytial virus, including mycoplasma, and there is no vaccine for mycoplasma in this year's pandemic, but there is a vaccine for influenza, so the flu vaccine can be vaccinated, and there is no targeted vaccine for adenovirus.
For teenagers, who spend a lot of time in school and some of them need group housing, these children also need to pay attention to the following aspects when living together.
Li Huiying, Director of the Comprehensive Pediatric Ward of Xuchang Central Hospital:
