Introduction Indirect transmission of viruses occurs when viruses are released into the environment from an infected host, a susceptible individual comes into contact with the virus, and the susceptible individual becomes infected. Indirect transmission can occur through exposure to virus-laden air, food, water, or fomites (CDC, 2020). Hands can touch virus-contaminated fomites and viruses can be subsequently transferred to the skin (Anderson & Boehm, 2021).

Moreover, we created separate heatmaps for three major COVID-19 waves that occurred during our analysis period.
