Yes, there is. JAMA recently published an article about temperature and it’s associacion with the instantaneous reproduction number of SARS-CoV-2.

Dear Andres, thank you for your contribution

In my opinion, the most important protective factor is the genetic backgroud, as described below:

I was interested that humidity was also a relevant factor; see the Rubin et al (2020) given as a link above by Andres Quevedo.

In the future, oncoming temperature and humidity changes could, perhaps, inform political leaders that social changes need to be considered, to anticipate possible climatic related rises in cases of COVID-19?

Dear Pietro Rmanuele Napoli, thank you for the relevant contribution

Dear Mary Wilson, thank you for sharing with us your point of view

Please see the link below.

Please have a look at the following link which also found that the temperature and relative humidity were both negatively related to daily new cases and deaths.

The second wave in a few countries and the ongoing first episode in many countries challenges the negative correlation concept.

Dear Harasit Kumar Paul , thank for your contribution to this discussion

Article High Temperature and High Humidity Reduce the Transmission of COVID-19

Arvind Singh , Thanks for the links.

I have already seen several works that were submitted before May 2020.

Everyone believed, the spread of Covid-19 will drop and the number of deaths will be lower during the summer.

But the opposite happened with the first or second wave in some countries and the number of cases exploded in several countries during the summer.

Do you really think there is an association between temperature and covid-19?

Ouaïl Ouchetto

Yes, I believe an association between temperature and COVID-19. Warm temperature slows the transmission of SARS-CoV-2 virus.

Thanks!

Sim, mas o principal fator é a falta de isolamento social.

Alexsande Oliveira Franco , I agree with you.

Arvind Singh ,

if we look at the current Covid-19 figures, we find that the summer has no influence on the spread of Covid-19.

https://www.worldometers.info/coronavirus/

The number of confirmed cases reached its maximum during summer in several African countries: Morocco, Algeria, Egypt, ...

Middle East: Saudi Arabia, United Arab, Qatar, Yamen, Kuwait, Iraq

A second wave in some European countries such as Germany, Spain, France, ...

Same thing in the USA, Mexico, ...

the list is very long of countries that contradict this hypothesis

@ Ouaïl Ouchetto

Why USA and many European countries despite of having better health facilities compared to African countries are badly hit by COVID-19?

The main reason for this is that warm temperate and cold climates favour the spread of the SARS-CoV-2 virus compared to arid and tropical climates.

Thanks!

No, it has been transmitted in hot and cold climates and this pandemic is still spreading

Dear Arvind Singh ,

We are talking about the correlation between the number of cases and temperature.

I gave several examples of countries where the number of cases increased during the summer.

So it has nothing to do with the health system of countries. Moreover, the health system of certain African countries such as South Africa or the countries of the Maghreb is not worse than that of other countries like India, etc.

This paper has been submitted in March.

Unfortunately this study was done in March. Everyone expected the number of cases to drop over the summer. But , this number exploded in some countries during the summer.

Many research articles support that high temperature is not favor for Covid-19.

I agree with Professor Ouchetto. The causation and spread of covid19 is multi factorial. Was doing some time trend analysis and prediction modeling with some available data but cannot share it in the forum due to permission issues. There are complex interplay of several factors. This virus may not be a natural one but may be genetically modified may be in some research laboratories as there are so many facets involved in its transmission.

Dear Md. Abdur Razzak Choudhury , I agree with many papers submitted in March and April support that the temperature is not favor for Covid-19.

But the reality is different. You just have to look at the number of cases which exploded in quite a few countries during the summer.

Sumanta Chakraborty thank you for your relevant contribution. Until now, I don't think we know everything about this virus. Effectively, there are so many facets involved in its transmission

...results indicate that mean temperature has a positive linear relationship with the number of COVID-19 cases with a threshold of 3 °C. There is no evidence supporting that case counts of COVID-19 could decline when the weather becomes warmer, which provides useful implications for policymakers and the public.

Temperature significantly changes COVID-19 transmission

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7182516/

In food, current evidence on other coronavirus strains shows that while coronaviruses appear to be stable at low and freezing temperatures for a certain period, food hygiene and good food safety practices can prevent their transmission through food.

Specifically, coronaviruses are thermolabile, which means that they are susceptible to normal cooking temperatures (70°C). Therefore, as a general rule, the consumption of raw or undercooked animal products should be avoided.
