In autumn and winter, influenza (referred to as influenza ) enters a high-incidence period. Affected by the new crown pneumonia epidemic, may have the risk of new crown and respiratory infectious diseases such as influenza this winter and next spring. Once the new crown and influenza are combined, the impact on the body may have a 1+12 effect. Changsha Disease Control reminds the general public: Be the first person in charge of your health, develop good personal hygiene habits, pay attention to enhancing your body's resistance, enhance your awareness of disease prevention, and beware of the combined risks of influenza and new coronary pneumonia.
The early symptoms of the new coronavirus and influenza are very similar
The new coronavirus and influenza are both acute respiratory infectious diseases, and the early symptoms of are very similar . Once a large number of cases with respiratory infection symptoms are found for treatment, will increase the difficulty of medical institutions to differentiate the diagnosis of new coronavirus cases, and at the same time increase the risk of spreading the new coronavirus.
Once the new crown and influenza are superimposed, a 1+12 effect may be produced
According to foreign research reports, people with influenza have a higher risk of infection with the new crown virus, and are more likely to induce inflammatory factor storms after being infected with the new crown virus. Patients with both influenza and new crown pneumonia have a risk of death that is 2.35 times that of patients with only the new crown pneumonia.
Stay away from influenza, what should we do?
. Get influenza vaccination in a timely manner : Getting influenza vaccination every year is an effective means to prevent influenza and can significantly reduce the risk of influenza and serious complications for vaccinated people.
2. Develop good hygiene habits : Wash your hands frequently and try to avoid touching your eyes, nose or mouth; when coughing or sneezing, cover your mouth and nose with tissues, towels, etc.
3. Pay attention to enhancing body resistance : Diet reasonably, sleep adequately, exercise appropriately, and maintain a positive and optimistic attitude.
Why does the flu vaccine need to be vaccinated every year?
. Influenza vaccine strain composition changes. influenza virus is very prone to mutation, and the components of the influenza vaccine will be effectively adjusted according to the monitoring results of the global influenza monitoring network. Compared with the previous year, the A (H3N2) subtype and B (Victoria) have replaced the strain ingredients this year. The new ingredient vaccine is more targeted for preventing the currently prevalent influenza virus.
2. Antibody level decreases. The immunity obtained by humans after being infected with influenza virus or getting vaccinated will decay over time. The protective effect of inactivated influenza vaccine on antigen-like strains can be maintained for 6-8 months, and the serum antibody level of is significantly reduced after one year of vaccination.
What are the available influenza vaccines?
. Trivalent inactivated vaccine: 0.25ml specifications are suitable for infants and young children aged 6 to 35 months; 0.5ml specifications are suitable for people aged 3 years and above;
2. Quadrivalent inactivated vaccine: 0.25ml specifications are suitable for infants and young children aged 6 to 35 months, and 0.5ml specifications are suitable for people aged 3 years and above;
3. Trivalent live attenuated vaccine (nose spray) : 0.2ml specifications are suitable for people aged 3 to 17 years old.
Citizens can choose the appropriate influenza vaccination as needed.
Influenza vaccination timing
According to the "Technical Guidelines for Influenza Vaccination in China (2022-2023)", antibodies with protective levels can be produced after 2 to 4 weeks of influenza vaccine, and the antibodies begin to decay after 6 to 8 months. The time and duration of peak influenza activity in various parts of my country are different every year. In order to ensure that recipients receive immune protection before the high-influenza season, recommends that be immunized by the end of October; can provide immunization services throughout the epidemic season for subjects who have not been vaccinated before the end of October. In the same flu epidemic season, people who have completed the full vaccination process according to the vaccination procedure do not need to repeat vaccination.
people below need protection of influenza vaccine
. Medical personnel, including clinical treatment personnel, public health personnel, health quarantine personnel, etc.;
2. Participants and security personnel in large-scale events;
3. Vulnerable groups and employees in nursing homes, long-term care institutions, welfare homes and other places of gathering;
4. People in key places, such as teachers and students in childcare institutions, primary and secondary schools, detainees and staff in prison institutions, etc.;
5. Other high-risk groups in flu, including Home-based elderly people aged 60 and above, children aged 6 months to 5 years old, chronic diseases, family members and caregivers of infants under 6 months of age, etc.
