The coronavirus diseases 2019 (COVID-19) caused by a novel coronavirus which was first identified in Wuhan, a city of Eastern China. What began as an epidemic mostly constrained to China has now become a worldwide pandemic. Previous studies on airborne viruses comparable to coronavirus show that there is a notable relationship between the climate indicators and transmission of viruses. This study was conducted to observe the relationships of climate factors on the number of cases and the number of deaths by Coronavirus Disease -19 (COVID-19) and the spread of it in the USA. The datasets for this research have been collected from the regular updates of The New York Times, weather2visit, Current results (weather and science fact), and Americas Health Rankings from 1 April 2020 to 30 April 2020. Findings of our study observed that the highest number of infected people and death was found in New York in April 2020. Kendall's tau-b and Spearman test of correlation reveals that minimum temperature, average temperature, absolute humidity, and air pollution are significantly correlated with the transmission of this virus and the sum of deaths by COVID-19. The verdict of this article will boost the native and international health organizations to understand the spread of COVID-19 in different environmental situations.

Background Nipah virus is a zoonotic agent causing diseases with extremely high mortality rate and several outbreaks have been reported from different parts of the world. Bangladesh is one of the country having repeated Nipah outbreaks since 2001.Objective To prevent an outbreak, it is necessary to understand public awareness and knowledge about the epidemic agent. This study was aimed to determine the level of knowledge and awareness related to NiV infection and to assess the potential risk of NiV disease among the rural population of Bangladesh.Methods This cross-sectional study was conducted with the participation of 200 respondents from different villages of Bangladesh. The data were collected through face-to-face interviews in January 2021 using structured questionnaire.Results From the survey it was found that 58.5% respondent of the study unknown about the term Nipah virus. However, maximum people seem to be aware of the fact that a virus infected person should be isolated as they can spread the disease further. The awareness level of the people is classified as “very poor”, “poor”, “good” and “excellent” with a percentage of 20%, 23%, 25.5% and 31.5% respectively based on some questions. Bionomial regression analysis showed that education and government campaign were variables associated with the awareness of NiV disease.Conclusion Education and government campaigns need to be stepped up to make rural people aware about this zoonotic disease.
