How is tobacco mosaic virus spread?
Its spreaded by contaminated leaves rubbing against a healthy plant or contaminated worker hands (farmers or plant growers in general) but It can't be spreader by bugs unlike other plant diseases
direct contact- infected leaves touching non infected and through contaminated tools or farmers hands
at 2:47 it said that antiretroviral drugs save you but do you have to take them for your whole life or just once and leave it at that?
Hi Oscar, it's quite a complex subject; usually the answer is yes for the rest of your life, though there are cases when that's not true :)
Hello

This video is very similar to the format Osmosis uses
Ah Osmosis are amazing! We'll take that as a compliment 🤩
