Introduction
The global distribution and severity of COVID-19 have been markedly heterogeneous. Seasonality has been indicated as a contribution to regional variability, although the relationship between weather and COVID-19 is still unclear, and outside environments have been the focus of investigation. Even though laboratory and epidemiological research have proven the impact of ambient temperature on the transmission and survival of coronaviruses, nothing is known about the weather's impact on the spread of COVID-19.
Objectives
This study investigates the effects and association of temperature, humidity, precipitation, wind speed on the rising of COVID-19 cases in Johor, Malaysia
Methodology
From January 2021 to December 2022, daily COVID-19 case data was gathered from the COVIDNOW Malaysian website dedicated to covid-19, while satellite climate data for the same period was taken from the official website of the National Aeronautics and Space Administration (NASA). A descriptive analysis was undertaken to characterise all the important variables across the study period. Correlation analysis was conducted to investigate the linear relationship between covid-19 cases and climate factors.
Results
The result shows there is positive correlation between COVID-19 cases towards rainfall and temperature (p value <0.01). Also, the results show there is no correlation between COVID-19 cases towards windspeed and humidity.
Conclusion
The results indicate that climate characteristics are useful for minimising the uncertainty surrounding the severity of future COVID-19 transmission. These correlations between climate conditions and covid-19 cases can be used to generate early warning for any future epidemic, allowing for the adoption of stringent regulations, the preparation of healthcare service plans, and the targeting of vaccination coverage.
