After hearing and reading a lot of opinions from experts in the past few months, we have a right to ask ourselves: Does the warm spring bring us the containment of the new coronavirus Sars-CoV-2? However, the thesis that higher temperatures and spring bring relief in the fight against Covid-19 remains controversial. There are several opinions about the Corona virus and spring.
In February, virologists worldwide claimed that higher temperatures would make it more difficult for the new Sars-CoV-2 coronavirus to spread, and that the spring epidemic, like seasonal flu, would weaken significantly – at least that was hope. Just three months ago, a study by Chinese researchers (https://www.medrxiv.org/content/10.1101/2020.02.22.20025791v1) provided promising arguments for this. A new analysis now shows us that this hope was deceptive.
After a team of researchers from Harvard University (https://www.medrxiv.org/content/10.1101/2020.02.12.20022467v1) analyzed the course of the Sars-CoV-2 outbreaks in various Chinese provinces and in some other areas that the virus could not only spread to dry and cold regions. The pathogen was able to spread even in high humidity. The spread of the virus, which has been exponential in many places in Europe in the past two months, confirms the fear of the virus. Experts say that spring alone will not bring any slowdown. There is concern that warmer weather with humid air will not make the epidemic go away.
This is one of the reasons why the keyword “take responsibility” has become the new COVID-19 strategy. Read on in the text how you can protect yourself and others from infection.
Does a face mask protect me from the Corona virus?
The Corona virus is transmitted via droplets, which are primarily caused by coughing and sneezing. It is therefore obvious why we need to wear a face mask especially in public.
The reason for this: Not everyone that is infected shows typical symptoms. They are often far too mild or nonexistent. Sometimes you are not even aware that you carry the virus and potentially pose a danger to people with a weak immune system.
An experiment with hamsters shows that masks protect against Corona infections
• Researchers have examined for the first time how reliable masks are in protecting against infection with Corona virus.
• In an experiment with hamsters, a simple surgical mask significantly increased protection against infection with Corona virus.
• However, other types of masks, such as self-made ones, have not been examined.
The results were published in the journal Clinical Infectious Diseases (https://academic.oup.com/cid/advance-article/doi/10.1093/cid/ciaa325/5811871?searchresult=1). In the study the scientists describe their experimental setup: a cage with healthy hamsters was placed next to one with infected animals. The researchers then stretched the fleece, as used in surgical masks, over the cages – and then ensured an air flow that posed a risk of infection.
The result: In the study, the risk of infection of healthy hamsters decreased by 75 percent if there was face mask material on the cages of infected animals. If there was only protection in healthy animals, the risk of infection was halved.
How can I protect myself against infection?
To protect against viruses, it is recommended strict hand hygiene. Infectious diseases are most often transmitted through our hands. Regular, thorough hand washing with soap and water protects. What many do not know: The hands should be cleaned for at least 30 seconds so that pathogens are rendered harmless.
Other important hygiene rules are:
• When you cough or sneeze, keep away from other people and turn away.
• Avoid physical contact with people who show a fever, cough, and other flu-like symptoms.
• If you have a fever, cough, and difficulty breathing, seek medical help early.
In view of the flu, these measures are advisable everywhere and at any time.
