French expert: New crown virus transmission cannot prevent virus transmission from the seasonal heat waves.

Overseas Network, June 21st. The cause of the new crown in France has risen again. Medical experts are worried that the epidemic will start again, and warn that the heat waves that have swept France recently cannot prevent the spread of the new crown virus. The transmission of this virus is regardless of the season.

According to the Parisian report, in the past week, high temperatures in many places in France have broken records. However, the epidemic data has risen as much as temperature. The incidence of more than 50 provinces including the province and Veda increased more than doubled. Anto Villao, director of the Global Health Research Institute of Geneva and epidemiologist, warned that "the French epidemic curve is exponentially growing, which indicates a new wave of epidemic."

French public health professor Philip Amurier said, "There is no doubt that the role of high temperature has been overestimated." He explained that summer temperature rises, which is often a "brake factor" of the spread of new crown viruses, but the new crown virus virus Unlike the flu virus, the flu virus is a typical winter virus, while the spread of the new coronal virus does not have real seasonality. The new crown virus is indeed more sensitive to temperature, and the risk of spreading in the hot and dry environment is lower. However, if the heat waves in summer can prevent the spread of the new crown virus, it is a misjudgment.

Philip Amuryer also pointed out other various influencing factors of the spread of the new crown virus, which may be more decisive in the next few weeks of virus transmission.

The first is the spread of the new mutant strain and BA.5 of the new crown virus of Omikon. The proportion of BA.5 infected people in France has continued to rise, and the peak of the epidemic that Portugal has just experienced was triggered by BA.4 and BA.5, which also affects France.

In addition, the protection effect provided by the new crown vaccine is weakening. In February 2022, the new French crown "strengthening needle" vaccination has ended, and few people take the second dose of "enhanced needle". And a recent study shows that in the face of Omircong's evolutionary branch BA.2, the high -level protection time provided by the new crown vaccine has dropped from six months to four months, which means that the immunization of the French population has entered a weakness. period.

Under various factors, medical experts are worried that a new wave of epidemic will outbreak in autumn. Starting in July, France will enter the "vacation season" and people will embark on a summer vacation journey. Although the risk of spreading the new coronary virus is lower, this cannot be generalized. Philip Amuryer suggested that it is best to avoid close contact such as crowds and hugging and kissing. Take a mask as much as possible by public transport. High -risk people should take the second dose of "enhanced needle" as soon as possible. (Overseas Network-Paris-Lu Jia)
