Syphilis (TP) is a spirochete prokaryotic cell type microorganism. It is less resistant to physical and chemical factors than bacteria, resistant to cold and not heat and dryness, and can die at temperatures of 56°C for ten minutes or 60°C for one minute. While 75% alcohol, 0.1% hydrochloric acid and sulfuric acid take 10 to 15 minutes to kill.

The AIDS virus (HIV) is also weak against physical and chemical factors, but it is sensitive to heat, and is more tolerant of low temperatures than high temperatures. The same at 56 ℃ thirty minutes can be killed, but in the room temperature of 20 to 22 ℃, the virus activity, but also can remain for seven days. HIV alkali resistance does not resist acid, 0.1% of bleach, 75% of alcohol, 0.3% of hydrogen peroxide, 0.5% of Lysol have inactivation of the virus, but is not sensitive to ultraviolet light.

Human papillomavirus (HPV) is highly infectious and can survive for more than two months at -20°C and for 3-5 days at 40°C. It takes 30 minutes to inactivate the virus at 56°C but only a few seconds at 100°C. It can also be inactivated by ultraviolet light for 10 minutes. Ultraviolet radiation for ten minutes can also inactivate the virus. Disinfectants such as hypochlorite and peracetic acid (84 disinfectant) are very sensitive and can be killed very quickly. But some commonly used disinfectants such as alcohol, isopropyl alcohol and glutaraldehyde cannot inactivate the virus.

That's why it's important to choose the right disinfectant for different pathogens, and 75% alcohol isn't a cure-all.

In this HIV and HPV are viruses and syphilis is a syphilis spirochete, not a virus. They are described separately below:

[Syphilis spirochete] It is difficult to leave the body to survive, boiling, drying, soapy water, general disinfectant can kill the pathogen in the short term. 75% alcohol is easy to kill.

[HIV, HPV viruses] One is an RNA virus, the other is a DNA virus, the virus has little resistance outside the body, heat, ethanol, hydrogen peroxide and other treatments are easy to kill.

But be careful: these are pathogens in vitro, they don't work on the ones that have infected the cells and are inside the body's cells.

I'm Dr. Jay Shih, the most history-savvy physician in the physician community, welcome to my attention~~

You're still staggering me when I see this question, why is it still a problem?

To work backwards, if syphilis, HIV, and HPV could be killed by medical alcohol, and that too at 75 degrees, then syphilis, HIV, and HPV would simply not exist in this world. The world's problems would be perfectly solved.

What does topical medical alcohol kill?

Medical alcohol is basically generally used for disinfection, in daily life, we generally used to disinfect wounds, to achieve the role of disinfection and sterilization, 75 degrees of alcohol can kill bacteria, note that bacteria, not viruses. These are all part of the virus series, so the alcohol is not killed drops ~ ~ but bacteria can only be killed with 75 degrees of alcohol, there are 95 alcohol on the market, too high alcohol will form a protective film on the surface of the bacteria to prevent bacteria from entering, but can not kill the bacteria. But it should be noted that alcohol can not kill the spores. Spores need to be autoclaved.

How are you?

Alcohol disinfection and sterilization principle] 75% alcohol and bacteria osmotic pressure is similar, can be in the bacterial surface protein before denaturation gradually and continuously to the bacterial internal infiltration, so that all the bacterial proteins dehydration, denaturation and coagulation, and ultimately kill the bacteria.

Sexually transmitted disease viruses such as syphilis, warts, herpes, and HIV will die in 10 minutes with 75% disinfection.

I hope it works for you.
