Use of Weather Variables in SARS-CoV-2 Transmission Studies

Area of Science:

• Environmental Science
• Atmospheric Science
• Epidemiology

Background:

• The persistence of SARS-CoV-2 raises questions about its sensitivity to seasonal environmental changes.
• Existing studies on SARS-CoV-2 transmission and variables like temperature and humidity have yielded varied results.
• A potential reason for differing outcomes is a limited understanding of atmospheric science and global seasonal differences.

Purpose of the Study:

• To provide insights that may explain discrepancies in studies examining environmental variables' impact on SARS-CoV-2 transmissibility.
• To promote improved variable selection and interpretation in future COVID-19 and infectious disease research.

Main Methods:

• This is a perspective piece, not an empirical study.
• It involves reviewing and synthesizing existing knowledge on atmospheric science and its relation to infectious disease transmission.
• Focuses on physical and chemical principles of meteorological variables and global seasonal variations.

Main Results:

• Differing results in SARS-CoV-2 transmission studies may stem from inadequate understanding of atmospheric science.
• Global seasons present distinct environmental conditions in tropical versus temperate zones.
• Key meteorological variables require careful consideration for their physical and chemical properties.

Conclusions:

• A deeper grasp of atmospheric science is needed to accurately assess environmental influences on SARS-CoV-2.
• Understanding seasonal variations is critical for interpreting transmission dynamics.
• This perspective aims to enhance the methodology and interpretation of future research on infectious diseases.
