The main aim of this paper is to know whether the temperature have any impact on the increase of corona virus. Covid-19, this name has brought a drastic change in our day-to-day life. People of Telangana have lived through 10 months of the Covid-19 pandemic and there might be more to come. Till date 2.8lakh official cases of covid-19 have been registered in Telangana and there may be many more which have gone unnoticed. In our busy life, we are neglecting our health and no one is maintaining a proper hygiene. And we have been more addicted to junk foods rather than nutrition, because of this reason covid-19 became a threat to our life. So proper precautions and awareness must be spread among people to avoid spread of virus. Fever, cough, breathing problems etc are the symptoms of this covid-19. If we neglect these symptoms it leads to a severe problem like pneumonia, kidney failure and eventually leads to death of that person. At this moment we don’t have any vaccine to cure this disease, the only prevention or avoiding corona is to boost our immune system. To overcome this pandemic situation, firstly we need to know the important factors that increases in covid-19 cases. In this paper, machine learning techniques are used to identify how temperature varies with the increase of covid-19. Which means we find how the effect of temperature depends on the number of covid-19 cases in Telangana.
