 Can you treat coronavirus by injecting disinfectants like bleach or isopropyl alcohol into your body? The short answer is absolutely not and the long answer, you have got to be kidding me. Bleach and isopropyl alcohol, like many active chemicals, can destroy viruses on surfaces and in the air but they're also toxic, which means that injecting them into your body or inhaling them is a really, really bad idea. It's a little like setting fire to yourself because you've heard that heat kills germs. So if someone does suggest you start putting toxic chemicals into your body to protect yourself against coronavirus, just say no. And remember, stay safe.
