? Human respiratory syncytial virus (HRSV) is one of the main pathogens that cause respiratory diseases and deaths of infants, the elderly and some adults all over the world. China is one of the countries with high prevalence of HRSV in the world. The research shows that influenza virus, HRSV and human rhinovirus are the top three virus pathogens in China in 2009-20 19, accounting for 28.5%, 16.8% and 16.7% respectively. Among children, HRSV is the virus with the highest detection rate, with the detection rate of 25.7%, which is much higher than that of influenza (14.2%). The detection rate of school-age children (8. 1%) and adults (4.5%) decreased gradually, while the detection rate of the elderly increased slightly (7.4%). 1. What is HRSV virus?
HRSV is an RNA virus, belonging to Pneumoniae and Orthopneumonia. After HRSV infection, the incubation period is usually 2-8 days, and the main clinical manifestation is respiratory infection. The early infection of HRSV is mostly confined to the upper respiratory tract, and its clinical manifestations are nasal congestion, runny nose, cough and hoarseness. Most of the symptoms of children infected with HRSV will disappear within 1-2 weeks, and a few can develop into lower respiratory tract infection, which is more common in infants under 2 years old. Clinical symptoms include cough and wheezing, a few of which can be further aggravated, accompanied by shortness of breath and difficulty in eating, and severe cases can develop into respiratory failure. Experts in disease control and disinfection services say that infants and young children are at high risk of RSV infection. Studies have shown that more than 60% of infants with acute lower respiratory tract infection and 80% of infants under one year old are infected by syncytial virus. In addition, adults and the elderly with low immune function are also high-risk groups of respiratory syncytial virus infection. Second, is there a high probability of getting seriously ill after being infected with HRSV?
? First of all, it should be noted that infection with HRSV can not form permanent immunity, and it may be infected many times in the future. It is the most common cause of pneumonia and bronchiolitis in infants. Every year, there are about 3,365,438+million new cases of acute lower respiratory tract infection caused by HRSV in children under 5 years old worldwide, of which about 65,438+00% need hospitalization, and about 2%-5% of hospitalized children die. Young children and people over the age of 60 are more likely to get seriously ill after infection.
What symptoms do you need to see a doctor immediately after you are infected with HRSV?
HRSV infection can not only cause respiratory diseases, but also cause other system diseases, such as myocardial damage and cardiac insufficiency caused by cardiovascular system involvement. Central nervous system involvement can lead to central apnea, epilepsy, encephalitis and so on. In addition, in rare cases, hypothermia, rash, thrombocytopenia and conjunctivitis may occur. If the baby has typical respiratory symptoms, including increased respiratory rate, cough and wheezing, accompanied by irritability or feeding difficulties, and "three concave signs" or other abnormal conditions when inhaling, it is recommended to seek medical advice in time. 3. How does the 3.HRSV virus spread? How to prevent HRSV infection?
Respiratory syncytial virus can be transmitted through respiratory droplets, aerosols and pollutants. Hrsv is mainly transmitted through the nasopharyngeal secretions of virus carriers, and the aerosol formed by nasopharyngeal secretions can spread within the radius of 1 meter. If you are in close contact with virus carriers, you will inhale aerosols. When touching objects contaminated by viruses, viruses may enter the human body through the mucous membranes of eyes, nose and mouth and spread. Therefore, Fan Tong Biological Disinfection Service believes that the main means to prevent hrsv is to cut off the transmission route through environmental disinfection service sterilization.
In addition, when it comes to preventing virus infection, there is no mature vaccine for hrsv at present. Experts in disease control and disinfection services said that for the prevention of susceptible people, we should pay attention to washing hands frequently, avoid unclean hands touching eyes, mouth and nose, develop good personal hygiene habits, wear masks in time, and reduce the number of people entering and leaving crowded places. In the absence of a mature vaccine, Shanghai Fantong Biological Disinfection Service Company believes that the effective way to prevent infection is to do a good job in household cleaning and disinfection services and pay attention to family health. ? Fourth, the family environment disinfection service method-Fan Tong bio-vaporized hydrogen peroxide disinfection robot
? Hydrogen peroxide is a food-grade high-grade disinfectant. Colorless, odorless and non-irritating, it has high-efficiency broad-spectrum bactericidal effect, can kill all bacteria, fungi and viruses, and has a good killing effect on cell spores. After disinfection, only oxygen and water are decomposed, and there is no residue and pollution, which is very safe and environmentally friendly. Vaporized hydrogen peroxide disinfection service robot diffuses gaseous 35% hydrogen peroxide liquid into the air through high-temperature flash evaporation, releases hydroxyl radicals to attack cells in many ways, and promotes microbial inactivation, thus achieving high-level sterilization effect. The vaporized hydrogen peroxide disinfection robot developed by Shanghai Fantong Biological Disinfection Service Co., Ltd. can better diffuse and spray hydrogen peroxide, continuously transport it, give full play to the strengthening role of hydrogen peroxide, and help hydrogen peroxide fully disinfect air and object surfaces. The vaporized hydrogen peroxide particles are less than 1 micron, which can be disinfected at 360 degrees without dead angle like air, and can cover all objects in the space, including floors, carpets, furniture, electronic equipment, mattresses, air conditioners, towels, toilets, kitchen supplies, etc. One machine can disinfect multiple areas, effectively killing germs on air and objects.
The vaporized hydrogen peroxide disinfection robot can work continuously and has a wide disinfection range. It can be used on different surfaces to kill all kinds of bacteria, up to the level of log6. The action time is fast, the area is disinfected in a short time, the operation is simple, and the cost is low. Winter and spring are the high incidence periods of infectious diseases, and many pathogens will attack the respiratory tract and lungs of human body, especially children and the elderly, who are high-risk groups of infection. Pay attention to Fan Tong's family disinfection and family health!
