Important! Health risk warning of Henan CDC in September
September is autumn, the temperature drops gradually, the temperature difference between day and night increases, kindergartens and schools in various places open one after another, the mobility and aggregation of people increase, and the Mid-Autumn Festival holiday and other factors are superimposed, which easily leads to the spread and popularity of many infectious diseases. Henan CDC hereby reminds the general public to pay attention to novel coronavirus infection, whooping cough, norovirus infectious diarrhea, dengue fever, school tuberculosis and food poisoning this month.
Key tips
1. novel coronavirus infection
The epidemic situation of COVID-19 in our province showed a fluctuating upward trend since the end of July, and it showed a fluctuating downward trend after reaching its peak in mid-August. In autumn, students start school one after another, and the Mid-Autumn Festival is approaching, the flow and gathering of people increase, and the risk of infection in COVID-19 increases. In crowded places such as public transportation and shopping malls, we should persist in personal protection to reduce the risk of virus transmission.
Protective measures:
1. Strengthen the protection of high-risk groups. Targeted measures are taken for high-risk groups such as patients with basic diseases and the elderly, so that cases can be found in time and treated effectively, and serious cases and deaths can be reduced as much as possible. Timely discover and deal with possible cluster epidemics in places where people gather, such as kindergartens, schools and old-age care institutions.
2. Pay attention to personal protection. Residents should wear masks in their daily trips, minimize unnecessary gatherings and keep social distance. Maintain good personal and environmental hygiene, wash hands frequently, often ventilate, pay attention to rest, pay attention to nutrition and enhance physical fitness.
3. Use drugs rationally and see a doctor as needed. After infection, asymptomatic infected persons and mild cases should take care of themselves at home, reduce contact with their roommates, use symptomatic drugs rationally according to relevant guidelines, do a good job in health monitoring, and go to medical institutions in time if the condition worsens.
2, whooping cough
Pertussis is an acute respiratory infectious disease caused by Bordetella pertussis, and its typical clinical manifestations are paroxysmal, spasmodic cough and crowing inhalation roar. The disease has a long course and can last for 2-3 months, so it is called "whooping cough". It is mainly transmitted by air droplets, but also by direct contact with respiratory secretions of patients. The population is generally susceptible, and infants without immunization history are at higher risk.
Protective measures:
1. Standardize vaccination. Vaccination with DTP vaccine can reduce the risk of severe pertussis and death in infants. According to the requirements of the national immunization program for children, school-age children should be vaccinated with DTP vaccine as soon as possible, and school-age children who have not been vaccinated all the time should be replanted as soon as possible.
2. Seek medical attention in time. Especially when infants and young children have paroxysmal spastic cough or have their own sudden cough after similar cases around them, they should take the initiative to seek medical treatment in time to reduce the risk of epidemic spread and serious illness.
3. Do daily protection. Keep good hygiene habits, wash your hands frequently and ventilate frequently, cover your mouth and nose with elbows or paper towels when coughing or sneezing, and pay attention to reasonable work and rest and proper physical exercise. Try to avoid crowded and poorly ventilated public places.
3, norovirus infectious diarrhea
Norovirus is a group of non-encapsulated RNA viruses, which has the characteristics of strong infectivity, rapid spread, short immune protection time and general susceptibility of the whole population. It is the most important pathogen that causes acute gastroenteritis. It can be transmitted through polluted water and food, and can also be infected by aerosol inhalation or contact with items contaminated by virus. Shellfish such as oysters and raw fruits and vegetables are common foods that cause infection. It is easy to spread in crowded places such as schools and kindergartens. In the autumn school season, kindergartens, schools and other educational institutions should do daily protection and strengthen health monitoring.
Protective measures:
1. Maintain personal hygiene. Pay attention to washing hands frequently to prevent diseases from entering the mouth, especially before and after meals and before preparing and processing food.
2. Pay attention to the hygiene of diet and drinking water. Do not eat uncooked food and unpasteurized milk, shellfish and seafood such as oysters should be eaten after deep processing; Fruits and vegetables should be carefully washed before eating, and do not eat unclean fruits and vegetables; Separate raw and cooked foods to avoid cross-contamination; Ensure the safety of water sources, do not drink raw water, and the selection of bottled water should meet the hygiene standards.
3. Pay attention to standardization. The environment or the surface of an object polluted by the patient’s vomit or excrement should be cleaned and disinfected by trained personnel with chlorine-containing disinfectants or other effective disinfectants. In the process of handling patients’ vomit, excrement and disinfection, you must do personal protection, wear masks and rubber or disposable gloves, and carefully clean and disinfect your hands after cleaning.
4. Dengue fever
Dengue fever is an acute infectious disease caused by dengue virus. Its clinical manifestations are persistent fever, accompanied by severe headache, myalgia, joint pain, nausea, vomiting and rash. In severe cases, bleeding, shock, organ failure and even death may occur. The disease is mainly transmitted by the bite of Aedes mosquitoes. September is still the peak of mosquito activity, so we should keep good environment and room hygiene in our daily life, reduce mosquito breeding and reduce the risk of infection. At the same time, people who travel and work in dengue epidemic areas should pay attention to personal protection to prevent mosquito bites, and do a good job of self-health monitoring after returning from epidemic areas.
Protective measures:
1. Do a good job in mosquito control. Clean up the accumulated water in indoor containers such as flowerpots and drinking fountains in time, clean up domestic garbage and sanitary dead corners, and keep the room clean and tidy. Install screen doors and screens in the room, and use mosquito-repellent incense, mosquito killer and electric mosquito swatter to prevent and repel mosquitoes.
2. Personal protection should be done when going to dengue epidemic areas. You should wear long-sleeved clothes and trousers, spray repellent and mosquito repellent on bare skin, use mosquito nets when sleeping, and try to choose hotels with air conditioning or screens.
3. Do your own health monitoring. After symptoms appear, you should seek medical advice as soon as possible, and actively inform the doctor of the relevant residence history for early detection, early diagnosis and early treatment.
4. Use of personal protective equipment. Personal protective equipment such as mosquito nets and mosquito repellent can effectively prevent mosquito bites, thus reducing the probability of dengue virus infection. In areas with frequent mosquito activities, it is recommended to use mosquito nets or apply mosquito repellent to protect yourself.
5, school tuberculosis
Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, which can invade many organs, and pulmonary tuberculosis infection is the most common. It is mainly transmitted by respiratory droplets, and healthy people may be infected by inhaling air droplets with tuberculosis. The main symptoms are cough, expectoration lasting for more than 2 weeks, chest tightness, low fever in the afternoon, fatigue, loss of appetite, emaciation, night sweats and so on.
Tuberculosis is one of the infectious diseases that schools focus on preventing and controlling. It is the beginning season of autumn recently, and it is a high incidence period of tuberculosis. Schools, parents and students should pay attention to the prevention and control of tuberculosis.
Protective measures:
1. Strengthen campus management. It is suggested that schools should strengthen the morning check-up, afternoon check-up and late check-up of students in school, implement measures such as tracking students’ absence from class and tracing the cause, and find tuberculosis patients and suspects in school as soon as possible.
2. Pay attention to personal protection and improve the body’s immunity. Pay attention to window ventilation, do not spit everywhere, and cover your mouth and nose with your elbow when coughing or sneezing. Reasonable diet, balanced nutrition, combining work and rest, ensuring adequate sleep and appropriate outdoor activities, enhancing physical fitness and improving body resistance.
3. Standardize the whole course of treatment. The whole treatment course of pulmonary tuberculosis is 6-8 months, and the whole treatment course of drug-resistant pulmonary tuberculosis is 18-24 months. According to the doctor’s standard treatment, most tuberculosis patients can be cured.
6. Food poisoning
Food poisoning is a major disease, which is caused by nausea, vomiting, abdominal pain, diarrhea and other symptoms after eating food contaminated by toxic and harmful substances or containing toxins. In September, the high temperature and high humidity weather continued in many places in China, which also created conditions for the proliferation of bacteria. Food is more prone to spoilage. With the large number of seafood on the market, it is necessary to pay attention to the pollution of seafood by Vibrio parahaemolyticus, which is easy to cause food poisoning.
Protective measures:
1. Pay attention to food hygiene and achieve "six noes": don’t eat uncooked and thoroughly cooked food, unclean fruits and vegetables, food of unknown origin, picking and eating wild mushrooms and wild plants, and don’t buy wild mushrooms picked and sold by individuals, and don’t buy wild mushrooms at mobile stalls.
2. When eating out, pay attention to the selection of catering units with complete licenses and good sanitary conditions. Buy food in supermarkets or vegetable markets with health protection.
3. Pay attention to personal hand hygiene, wash your hands before and after meals, before and after handling raw and cooked food and its packaging, after touching pets and disposing of garbage.
