New research confirms that COVID-19 has flu-like seasonal characteristics

A key question about the new coronavirus is whether it will become a seasonal virus like the flu, or will it spread equally at any time of the year? This is of great significance to the intervention measures

The first theoretical modeling study showed that climate is not the driving factor for the spread of new crown pneumonia.

In order to understand whether the new coronavirus is a seasonal virus, the research team first analyzed the relationship between the temperature and humidity at the initial stage of the spread of the new coronavirus in 162 countries on five continents before the implementation of relevant measures for epidemic prevention and control

The research team then analyzed how this link between climate and disease has changed over time, and whether this link is consistent across different geographic areas

In Europe, the first wave of epidemics weakened as temperature and humidity rose, and the second wave of epidemics rose as temperature and humidity fell

The same negative correlation was also observed when analyzing the instantaneous correlations on all scales of countries in the southern hemisphere that arrived late

Studies have shown that incorporating temperature into the transmission rate can better predict the rise and fall of different waves (epidemics)

The research coordinator and director of the Climate and Health Program at the Barcelona Institute of Global Health, Xavier Rhodo, said that this connection emphasizes the importance of air hygiene and the need to include meteorological parameters when evaluating and planning prevention and control measures
