Flu and cold is are common phenomenal because of presence of pollen. To get flu and cold does not translate to having COVID-19. But people are afraid being in contact with those with flu or cold.
Personally, because of continuous use of PPE; this is the first year that I haven't had the flu or even a cold (coronavirus); now that you mention it. I am glad that you mentioned that, so that is another "good thing" about the current Pandemic; less colds and flus. Someone else had asked what the "good things" about the Pandemic were, add this to more time to write and respond to RG, and improved environmental hygiene (as in decrease in many types of pollution). Thank you, stay safe. (The pollen is bad this year though where I live, I will post a picture when I find it, my car and the road were covered in yellow pollen, very bad)
