Recently, the number of reported influenza cases in Ningbo city has increased sharply compared with last week, an increase of 84.31%, and the nucleic acid positive rate of influenza-like cases has increased significantly.
Our city is already in the peak season of influenza epidemic in winter, so take precautions.
Influenza virus typing
Recently, samples of influenza-like cases were tested, and the positive rate reached 59.09%.
The prevalent types of influenza viruses are mainly type B (type BV) and type A (type H3N2).
Influenza epidemic characteristics
This year's influenza epidemic is violent. According to the monitoring data of Zhejiang Provincial Center for Disease Control and Prevention:
The number of influenza cases in 2019 has significantly exceeded the incidence of previous years.
The cluster epidemic has increased significantly, mainly in collective units such as childcare institutions, schools and nursing homes.
What should we do to prevent influenza?
[Symptoms of flu] Unexplained high fever, headache, some cough, sore throat, body aches, joint pain. In this case, you must go to the hospital immediately, don't carry it, and take antiviral drugs in time.
[Common cold symptoms] Generally, the body temperature is 37 degrees, not more than 38 degrees, and some people do not even have a fever, just runny nose and sneeze. Generally, take some medicine and take a rest at home.
【Difference in time】 Under normal circumstances, the common cold lasts for one week, while the flu is about 2 to 3 weeks.
【How to prevent influenza 】The most direct and effective way to prevent and treat influenza is vaccination. The best time to get the vaccine is from September to November, which is before the flu peak. If you miss this period, you can get the vaccine now. The elderly and children are advised to get vaccinations and take precautions in advance.
Another important way to prevent influenza is to wash your hands frequently. Avoid simply rinsing with water. Instead, wash them with soap each time. Do not go to crowded places to reduce the chance of infection. Exercise your body and improve immunity. Maintain a healthy life schedule.
Another cold air is about to arrive!
Beginning the night before yesterday, a new stream of cold air began to affect my country from west to east. At that time, the temperature in the central and eastern regions will drop by 4-6°C, and the temperature drop in some areas can reach more than 8°C. There will be 4- Level 5 northerly winds, especially in parts of the northwest, are expected to refresh their lowest temperature in the second half of this year. Cities such as Xi'an, Lanzhou, and Xining may spend the coldest morning since the beginning of winter on the 26th or 27th.
Afterwards, the cold air spreads to the south, and the temperature in the south will also drop. From December 27th to 28th, the lowest temperature in the middle and lower reaches of the Yangtze River will drop below 5℃, and in some areas it will even be below 0℃. For example, the lowest temperature in Hefei and Wuhan on the 27th was only -1℃ to -3℃.
The arrival of cold air also means the intermittent period of rainfall in the southern region. The Central Meteorological Observatory predicts that today, there will be light to moderate rains in eastern Southwest China, Jianghuai, Jianghan, Jiangnan, southern China, and most of Huanghuai. Most of the rain is over, and there will be sunny days with cloudy weather for 1-2 days.
Although the cold air is coming, the last snow of 2019 that everyone is looking forward to has not yet landed. Because the temperature is not low enough (generally, the near-surface temperature needs to be below freezing when it snows), so recently I have seen only "rain" but not "snow". In the last few days of 2019, the chance of people in Zhejiang seeing snow is very small. Perhaps the temperature in the mountains is low enough to be lucky enough to encounter the winter elves—snowflakes.
