Understanding COVID-19 Seasonality

What is a common belief about the effect of warmer weather on COVID-19?

• It will make the virus more deadly.

• It will have no effect.

• It will increase the spread.

• It will reduce the spread.

Which of the following is NOT a hypothesis for the flu's seasonality?

• Human behavior

• Genetic mutation

• Immune system response

• Environmental factors

How does humidity affect the transmission of respiratory viruses?

• Decreases virus survival

• Increases virus survival

• Makes viruses more contagious

• Has no effect

What happens to virus droplets in dry conditions?

• They become less stable

• They become heavier and fall

• They evaporate and become lighter

• They dissolve completely

In what way is COVID-19 different from the flu?

• It is not a respiratory virus

• It has been around longer

• It is less contagious

• It has a higher transmission rate

What is a key factor in slowing down virus transmission?

• Increasing the susceptible pool

• Decreasing the susceptible pool

• Increasing the number of cases

• Decreasing humidity

Why might COVID-19 not show seasonal patterns immediately?

• It is not affected by weather

• It has a short lifespan

• The susceptible pool is still large

• It is not a respiratory virus

What could potentially make COVID-19 seasonal in the future?

• Higher transmission rates

• Lack of treatments

• Increased global travel

• Development of immunity and vaccines

What is the current most effective method to stop the COVID-19 outbreak?

• Developing new strains

• Increasing humidity

• Waiting for warmer weather

• Self-isolation

What is the relationship between COVID-19 and other coronaviruses regarding seasonality?

• They all lack seasonality

• They all show pronounced seasonality

• Only COVID-19 is seasonal

• COVID-19 is unrelated to other coronaviruses
