Data from the WHO sentinel surveillance system in 84 countries and regions shows that the percentage of COVID-19 positive tests has been rising in the past few weeks. Overall, the proportion of positive tests exceeded 10%. This proportion fluctuates differently in different regions. In Europe, the positivity rate exceeds 20%. The World Health Organization is urging governments to strengthen vaccination campaigns and ensure that high-risk populations receive the vaccine at least once every 12 months. According to a comprehensive report by China Women's Daily, many people on domestic social media platforms have reported that they have "tested positive" for COVID-19, experiencing symptoms such as fever, cough, and body aches. On August 8, the Chinese Center for Disease Control and Prevention announced the latest infection of COVID-19. The data shows that the positive rate of COVID-19 in influenza like cases (either fever with cough or sore throat) in domestic sentinel hospitals is rising significantly. In the same period, the proportion of influenza like cases in outpatient clinics declined slightly but not much, indicating that the absolute number of patients with COVID-19 infection also increased. The data shows that the positive rate of COVID-19 in influenza like cases across the country has increased, from 8.9% from July 1 to July 7 to 18.7% from July 22 to July 28. The main epidemic strains are Omikjon variants, and China is mainly dominated by JN.1 series variants and XDV series variants. It is worth mentioning that the monitoring platform of the National Medical Center for Infectious Diseases has monitored the variation and fluctuation of COVID-19 Omicron virus strain. Since the first ten days of June, COVID-19 XDV. 1 and KP.2 mutants have been gradually detected, and the proportion of XDV. 1 has gradually increased to 40%~50%, but these mutants have not caused an increase in severe cases. According to the data from the China Center for Disease Control and Prevention, 203 new severe cases were found in the rising phase of the epidemic in July, and there was no significant increase in the number of severe cases compared with the rising phase of COVID-19 cases in February and March this year. Professor Zhang Wenhong, director of the National Medical Center for Infectious Diseases and director of the Infection Department of Huashan Hospital Affiliated to Fudan University, said that the global COVID-19 positive monitoring results showed that COVID-19 infection fluctuated in a cycle of half a year, and gradually became a phased epidemic respiratory disease in China. The World Health Organization issued a new warning that in the past eight weeks, the proportion of people diagnosed with SARS coronavirus type 2 infection in primary medical institutions in dozens of countries and regions around the world has increased five times, and the proportion of COVID-19 infected people hospitalized has also increased. Data from the WHO sentinel surveillance system in 84 countries and regions shows that the percentage of COVID-19 positive tests has been rising in the past few weeks. Overall, the proportion of positive tests exceeded 10%. This proportion fluctuates differently in different regions. In Europe, the positivity rate exceeds 20%. WHO calls on governments to strengthen emergency preparedness and vaccinate high-risk groups with COVID-19 vaccine and influenza vaccine. The technical director of WHO, Kolkov, pointed out that in recent months, no matter what the season, many countries have experienced a surge of COVID-19, including at least 40 athletes who tested positive for COVID-19 and other respiratory infections at the Paris Olympic Games. As the virus continues to evolve and spread, there is an increasing risk of more severe strains emerging, which may evade detection systems and fail to respond to medical interventions. High risk population: Vaccination at least once every 12 months. Although the number of hospital admissions (including intensive care) is still significantly lower than the peak of the epidemic, the World Health Organization is urging governments to strengthen vaccination activities and ensure that high-risk populations are vaccinated at least once every 12 months. Kerkov emphasized that as an individual, measures must be taken to reduce the risk of infection and serious illness. Nasal vaccines are still under development, but have the potential to address transmission issues and reduce the risk of further mutations, infections, and serious illnesses. A study just released by WHO shows that from December 2020 to March 2023, COVID-19 vaccine will reduce the death caused by the epidemic by at least 59%. Most of the lives saved are elderly people over the age of 60, who are at high risk of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) causing serious illness and death. The Epidemic Prevention Innovation Alliance and the World Health Organization recently jointly issued a statement calling on researchers and governments to strengthen and accelerate global research to prepare for the next pandemic. The statement emphasizes that expanding the scope of research is crucial to cover the entire pathogen family that can infect humans (regardless of their pandemic risk awareness), while also focusing on individual pathogens. The statement suggests using the prototype pathogen as a "guide" or "explorer" to expand the knowledge base of the entire pathogen family. In hot and humid weather, the immune system is prone to decline. Currently, it is the time of the year when the temperature is the highest, humidity is the highest, and the feeling of stuffiness and heat is the strongest. This environment can easily make people feel tired. Long term use of air conditioning leads to poor indoor air circulation and increased transmission of pathogens. If proper rest or excessive fatigue is not taken into account, the immune function of the human body may decline, resulting in symptoms such as fatigue, lack of energy, diarrhea, vomiting, respiratory infections, etc. These symptoms may be a signal of weakened immune system in the body. If fever symptoms occur, it is recommended to first use simple pathogen detection test strips for self testing. Although the accuracy of these tests may not be as good as professional tests in hospitals, they can help identify possible pathogens in a timely manner. If the symptoms are mild, you can take heat clearing and detoxifying drugs at home. If the symptoms are severe or self medication is ineffective, it is recommended to seek medical attention as soon as possible, preferably at a fever clinic or emergency department. To prevent the spread of COVID-19, the following should be done: wear masks: masks are an important measure to prevent the spread of COVID-19. It is recommended to wear masks when going to crowded places. Wash hands frequently: Keep your hands clean and wash them promptly after touching public objects or returning home after going out. Less gathering: Try to avoid crowded places as much as possible to reduce the chance of infection. Strengthen ventilation: Maintain good indoor ventilation, open windows for ventilation at regular intervals every day, and allow fresh air to enter the room. Enhancing immunity: A balanced diet, moderate exercise, and sufficient sleep can help strengthen the body's immunity and resist the invasion of viruses. Seek medical attention promptly after symptoms appear: If symptoms such as fever, fatigue, cough, difficulty breathing, decreased sense of smell and taste occur, it is recommended to wear a mask and seek medical attention promptly.
