Thank you sir @Muhammed Ashraful Alam for your information. I know it but you may be find many published paper which are related to weather. Thank you very much sir for your really nice comment.
Mostly, I think that there is no clear relationship with the climate with the disease and the number of injuries. In my country, Iraq, there were few numbers in the winter, but now that we are in the summer the numbers have increased more, knowing that there is talk that with the rise in temperature the infection decreases, but we saw the opposite.
Thanl you Dr. Ankur sir for your nice comment. I am agree with you but you may be find many articles where main objects are relation between COVID-19 & hot weather. That's why I asked such question.

Still there is no authentic study to relate weather with corona virus spreading. However, there is an observation that use of excess air conditioning system favors virus growth and spreads so quickly among people staying or working in the the same place. That is why, in some countries special SOPs are made for rental taxi services (such as Uber) and these taxi services are not allowed to use vehicle AC and windows must be opened during traveling.
There is no such article related with the relaion of temperature and Covid-19. But according to me when the wheather is humid, transmission rate is more as compared to the arid weather.
There is no evidence of a direct connection between climate change and the emergence or transmission of COVID-19 disease. As the disease is now well established in the human population, efforts should focus on reducing transmission and treating patients.
I recommend reading the article by Tosepu et al. (2020) "Correlation between weather and Covid-19 pandemic inJakarta, Indonesia", which is in open access.
According to the authors of this paper, "The extreme weather conditions that accompany long-term climate change may also contribute to the spread of the West Nile virus in the United States and Europe (Epstein, 2001). Certain climatic conditions can be considered as the top predictors of respiratory diseases such asSARS. Climate variables can also be a direct cause of biological interac-tions between SARS-CoV and humans. Optimal temperature, humidity, and wind speed are variables that can determine the survival and transmission of the SARS virus (Yuan et al., 2006). Changes in weather arevery significantly correlated with changes in mortality rates due topneumonia (Bull, 1980). Viruses can be transmitted by being influenced by several factors, including climatic conditions (such as temperature and humidity), andpopulation density (Dalziel et al., 2018 ). Research on climate change and covid-19 is still very limited so this research will contribute to ef-forts to prevent covid-19 disease (Tosepu et al, 2020)".
COVID19 ofcourse a pandimic people suffering different ways houvever, during lock down of majority of countries in the World, the environment has good impact, industries were closed almost stopped released of carbon.
In terms of climate, there seems to be no clear and direct relation established between COVID-19 at the moment. However, by intuition we can maybe imagine how they may be related.
1. Weather and propagation
Weather is an important factor to the propagation of diseases depending on whether viruses are transmittable airborne (through the process of advection). But again, there is not enough evidence supporting COVID-19 to be airborne (reference: https://www.who.int/news-room/commentaries/detail/modes-of-transmission-of-virus-causing-covid-19-implications-for-ipc-precaution-recommendations#:~:text=According%20to%20current%20evidence%2C,transmission%20was%20not%20reported.).
2. Weather and immune system
From the perspective of a human body, our bodies' immune system is also influence by climate conditions or its variations. Some level of immunity helps combat viruses including COVID-19.
On the other hand, does COVID-19 situation affect weather?
In urban climate, anthropogenic activities may affect meteorology (even air quality) of cities. If lockdowns are imposed, limited anthropogenic activities of a city may have an influence, hypothetically, to local or long-term weather.
The virus that caused the SARS-CoV-2 coronavirus pandemic (causing the Covid-19 disease) is one of the weather resistant. It breaks down only above 60 degrees Celsius, while the change of weather, eg from summer to autumn or winter, causes a greater incidence of various diseases of the respiratory tract in a significant part of the human population. In the temperate climate zone, these descents are caused by various viruses and in approx. 10 percent. various respiratory diseases caused by bacteria. In the zone where I operate in recent years, the winters are getting warmer, usually without snow and frost. As a result, the percentage of people who develop this type of disease may decrease. On the other hand, in elderly people, in people who have had other diseases or for genetic reasons, the immune system functions less well, the incidence of this type of disease is more frequent. These types of diseases and chronic diseases, cardiovascular insufficiency caused by an unhealthy lifestyle and a diet that is too high in fats and carbohydrates may appear as the so-called comorbidities in relation to SARS-CoV-2 Coronavirus infection. In such a situation, the likelihood of developing Covid-19 disease and severely falling ill with Covid-19 is high in the situation of this type of comorbidities. This is confirmed by the statistics of people who died of severe illness from Covid-19. In approx. 90 percent. or more of the deceased had other comorbidities that significantly worsened the effectiveness of the respiratory system and / or the immune system. Therefore, the weather has an impact on the development of the SARS-CoV-2 coronavirus pandemic, but not directly on this virus, only indirectly by increasing the scale of negative aspects related to comorbidities, mainly related to various respiratory diseases and the general decline in the body's immunity, which may appear in the fall and winter period.
Based on the global trends available to-date, there is no concrete impact on effect of weather on Corona-virus spreading
except for isolated hypothesis. Irony. we still don't exactly how it spreads and survives as all are the matters of ongoing research trials. Perhaps strict watch to check community transmission is highly desired.
It's not very clear if there's link between Covid-19 and weather conditions. There's a whole lot of questions yet unanswered regarding this issue. All we need now is successful completion of the various vaccines that are being developed.
@Ahasan Ullah Khan...actually lots of authors working on weather and COVID 19 and has published in high impacted journal. They are trying to find out relationship between whether and COVID 19 and also established a a relation but there is serious falsification if you compared one article to another and it is almost impossible to generalise in world level to established any relation between weather and COVID 19. Also there is no direct evidence between weather and COVID 19...i think COVID 19 is not controlled by any weather phenomena....but some pollutant gases around the metropolitan and industrial areas have been reduced due to lockdown to reduced transmission ....
You spotted a significant issue. There is a evidence that there is a relationship between COVID-19 and weather patterns:
1) Forster, P.M., Forster, H.I., Evans, M.J. et al. Current and future global climate impacts resulting from COVID-19. Nature Climate Change (2020). Open Access
There are no relation between Weather abd Covid-19. You may see my paper are given below ghe cite is-
Siddhartha Dan, Deepshikha Sharma, Mahasweta Mandal, Deepti Sharma, “Incidence of COVID-19 and Its Correlation between Temperature and Population Density,” International Journal of Scientific Research in Biological Sciences, Vol.7, Issue.2, pp.134-141, 2020.
I do think that there is a relationship between the weather and COVID-19 by affecting how long the virus survives in the environment and on surfaces thereby affecting the infection load of the virus per unit time. However, this needs to be validated by scientific testing in a well designed study.
Correlation is significant at the 0.01 level (2-tailed). In this study, the pattern of climate change provides a picture of the occurrence of covid-19 e in Jakarta. We found only temperature average was correlated with Covid-19, with the lowest average temperature of 26.1 °C and the highest temperature of 28.6 °C
Actually there is no direct relation between weather and covid-19. But one things need to know is longevity and susceptibility of covid-19 in different environment, this can effect on infection load from different objects. However, it requires scientific testing and validation.
In the context of Nepal, at the beginning of summer, large number of COVID cases found in Terai (hot place) but very less found in Kathmandu (comparatively cold place) but now, large cases found in Kathmandu and less in Terai. Is there any relationship between COVID cases and weather? I don't believe. It makes me confusion. any suggestions?
I totally agree with the results of @ Harasit Kumar Paul, which accords with Science and Virology and with what is known with other viruses. There are still issues to be resolved, especially why there have not been obvious impact of weather on the number of cases in some countries and there is need for more studies on this and other factors that may be contributing to the epidemiology of SARS-CoV-2.
Dear Ahasan Ullah Khan, following, the discussion-
Will climate change make COVID-19 worse?
There is no evidence of a direct connection between climate change and the emergence or transmission of COVID-19 disease. As the disease is now well established in the human population, efforts should focus on reducing transmission and treating patients.
However, climate change may indirectly affect the COVID-19 response, as it undermines environmental determinants of health, and places additional stress on health systems. More generally, most emerging infectious diseases, and almost all recent pandemics, originate in wildlife, and there is evidence that increasing human pressure on the natural environment may drive disease emergence. Strengthening health systems, improved surveillance of infectious disease in wildlife, livestock and humans, and greater protection of biodiversity and the natural environment, should reduce the risks of future outbreaks of other new diseases.
