Does 70 alcohol kill tuberculosis?
Alcohol has also been shown to kill viruses such as tuberculosis, herpes, hepatitis B, HIV, influenza, rhinoviruses, and coronaviruses, among others.

High-level disinfection traditionally is defined as complete elimination of all microorganisms in or on an instrument, except for small numbers of bacterial spores.
Can 50 alcohol be used as a disinfectant?
The Centers For Disease Control (CDC) recommend alcohol at a concentration of 50%-70% for use as a disinfectant and antimicrobial. Alcohol at this dilution efficiently penetrates the bacterial cell wall, disrupts the molecular confirmation, then destroys (denatures) the proteins and enzymes inside of the cell.
Why is 70% alcohol a better disinfectant than 95 alcohol?
“Isopropyl alcohol 70 percent, or isopropyl alcohol 99 percent diluted to 70 percent with purified water, kills organisms by denaturing their proteins. A 70 percent isopropyl alcohol solution dissolves their lipids and is effective against most bacteria and fungi and many viruses.”
What level of disinfectant is bleach?

What do hospitals use to disinfect?
Stringent disinfection reduces the risk of healthcare-associated infections (HAIs). Currently, there are five main EPA-registered chemicals that hospitals use for disinfectants: Quaternary Ammonium, Hypochlorite, Accelerated Hydrogen Peroxide, Phenolics, and Peracetic Acid.
Is alcohol a disinfectant?
About rubbing alcohol It’s a powerful germicide, which means it has the ability to kill a wide variety of germs, including bacteria, viruses, and fungi. Rubbing alcohol is used in healthcare settings to disinfect hands and surfaces, but can also be used as a household cleaner.
