COVID-19 pandemic will end someday, but how much it affects the humanity depends on preventive measures like wearing masks, washing hands frequently, keeping a safe distance from others, etc.
Let's practice social distancing and lower the risks of getting infected.
Now, it's a fact based on much research that wearing masks, maintaining social distancing and washing hands frequently will slow down and decreases the active COVID-19 cases.
1. I am unsure about how I used the word affect in the paragraph above. I used it to show two meanings: Less COVID-19 cases (wearing masks etc.) and More COVID-19 cases (not wearing masks etc.). Is this use of word correct in this sense?
2. I'm also uncertain about this phrase: depends on.
What I want to say is if we wear masks and do other things, it will help us reduce the COVID-19 cases but if we don't, that number will increase.
But for some important reason, I don't want to write it specifically. At the same time, I'm also hoping what I've written also conveys the same meaning without giving incorrect (like wearing masks will increase cases) information.
To verify whether I'm correct in this type of use or not, I found this similar sentence in Oxford Dictionary:
depend on/upon sth (not used in the progressive tenses) to be affected or decided by sth
Does the quality of teaching depend on class size?
In the sentence above, let's assume a large class gives better quality education and a small one gives poor education. So now, without specifying exactly this, the question clarifies both things! I hope you got my point.
But I'm not sure about the way I've used "depends" in the passage. Is it conveying what I want to say?
Given these two doubts above, somehow I'm feeling what I've written might mean that wearing masks, social distancing, etc. will create more disease rather than lessening it.
So finally, did I use those words accurately or have I given incorrect/false information?
