Millions of people around the world, including Pakistan, expect the new Novel Corona virus outbreak to subside or at least slow down as the weather warms.
But now scientific reports in the US and China have turned up the expectation that warming could reduce the spread of the new nasal corona virus-like disease, Cod-19, as a common cold and flu.
Experts at the US National Academy of Sciences in the United States quoted it as saying, “In countries where the weather is hot at the moment, such as Australia and Iran, the spread of the virus is very rapid, given that it can be said that someone else The increase in humidity and temperature cannot be imagined to reduce the number of cases.

American experts said experimental research reports the relationship between elevated temperatures, increased humidity levels and a reduction in the survival time of the corona virus.
But experts emphasized that several factors influence the spread of the virus from one person to another.
On the other hand, after reviewing 224 cities across China from the beginning of January to the beginning of March in China, it was discovered that daily temperature rise or humidity does not change the rate of spread of the Corona virus.
“Our research does not support the notion that high temperatures and strong sunlight could reduce the spread of Cod-19,” said Yai Yao, who heads the research team at Shanghai’s Fudan University. It is premature that hot weather can control Cod 19 ‘.
However, the research team said several factors may play a role in this regard, such as the increase of vitamin D levels in people on more bright days, which strengthens the immune system.

Ultraviolet rays of the sun also kill viruses like flu and common cold, and in most countries there are school holidays in hot weather, which also slows the transmission of the virus.
But does it work on Corona viruses as well?
To this end, the Chinese team conducted a complex analysis across China and compared the epidemic data with changes in daily temperature, sunlight and humidity.
In a study published in the journal European Respiratory Journal, scientists discovered that temperature rise does not change the ability of Cody 19 to spread, as well as adjusting temperature and humidity, there is no effect on spread speed. came.
The research team noted that these trends are similar to the outbreak of other corona viruses, the Merse epidemic in 2012, where the virus continued to spread to high temperatures in Arab countries.
Other diseases that transmit livestock to humans, such as Ebola or influenza pandemics, are unpredictable, he said.
However, he said the results of the research are not conclusive and more research and work on high temperature areas need to be done in this regard.

US experts also agree that further research reports on the outbreak may shed more light on climate implications for this outbreak.
But there is currently no evidence that the number of cases of this virus can decrease significantly in the summer.
He said that people around the world are not immune to this virus. Even if the virus spreads slows, its transmission from one patient to another will not be slow unless precautionary measures are in place. Will be.
Other medical experts also say the new findings refute claims that the virus will magically disappear as temperatures rise in April.

Unless effective treatment and vaccines are available to people, social distancing can be an effective strategy to reduce its spread, he said.
