High concentrations of smoke and dangerous air quality indexes caused by wildfires can increase the COVID-19 risk for groups of individuals such as firefighters or individuals living in nearby cities or evacuation zones. Research has shown that smoke and air pollution could increase the risk that individuals would develop more severe symptoms of the virus.

The rainy season often brings about seasonal influenza and symptoms such as a cold or fever, which resemble some of those symptoms characterized by COVID-19. Viral activity is also heightened during this rainy season, posing a threat for individuals getting exposed to COVID-19 (Rai et al., 2020).

Rainy Season Effect on Individuals during the COVID-19 Pandemic

Varying environmental conditions can increase the risk of COVID-19 exposure and severity for specific populations. Examples of such environmental conditions include:
- Rainfall and rainy seasons (associated with heightened viral activity and influenza-like symptoms)
- Wildfires (associated with smoke, poor air quality, and increased susceptibility or severity of symptoms)

Risk Factors For COVID-19

Smoking as a Risk Factor for COVID-19

COVID-19 comorbidities are high risk conditions that put patients at greater risk for infection and negative outcomes. Some COVID-19 comorbidities have been found to be: 
- Cancer 
- Cardiovascular Disease
- Diabetes
- Digestive Diseases
- HIV
- Hypertension
- Immunological Disease
- Liver Injury
- Obesity
- Renal disease
- Respiratory System Disease

COVID-19 Patient Comorbidities

People with weakened immune systems are at higher risk of getting severely sick from SARS-CoV-2. Because of this, they have the infection for a longer period of time due to their immune system not fighting it off as fast. If you are immunocompromised, the best way to prevent COVID-19 is to avoid being exposed to this virus. Precautions such as washing hands, cleaning surfaces have to be done more frequent for people with suppresed immune systems.
