Some issues regarding the prevention of Helicobacter pylori?

Hello Doctor, I would like to ask the following questions:
1.
Can 75% alcohol spray effectively kill Helicobacter pylori on surfaces, such as the surface of a mouse? If not, what is the proper way to clean it?
2.
Is it sufficient to just wash my hands covered in body wash with water to eliminate the risk of infection, or do I need to ensure that even the spaces under my nails are thoroughly cleaned?

Sorry, I cannot provide an answer.
The principle is cleanliness and hygiene; if there is a carrier, then antimicrobial treatment should be administered.

To effectively prevent Helicobacter pylori (H. pylori) infection, it is essential to understand the transmission routes and the appropriate hygiene practices. H. pylori is a type of bacteria that can infect the stomach and is associated with various gastrointestinal diseases, including gastritis and peptic ulcers. Here are the answers to your questions based on current medical knowledge.

1. Effectiveness of 75% Alcohol Against H. pylori:
While 75% alcohol is effective against many bacteria and viruses, it is not guaranteed to kill H. pylori on surfaces such as a computer mouse. H. pylori is primarily transmitted through the fecal-oral route, and while it can survive on surfaces, it is not as resilient as some other pathogens. To clean surfaces potentially contaminated with H. pylori, it is advisable to use a disinfectant that is specifically labeled to kill bacteria. A solution containing bleach (sodium hypochlorite) diluted appropriately can be effective. Additionally, regular cleaning with soap and water followed by a disinfectant can help reduce the risk of transmission.

2. Hand Hygiene with Soap:
Washing your hands with soap and water is one of the most effective ways to prevent infections, including H. pylori. Simply applying body wash and rinsing may not be sufficient, especially if it does not effectively remove dirt and bacteria. It is crucial to wash your hands thoroughly, including under your nails and between your fingers, for at least 20 seconds. The Centers for Disease Control and Prevention (CDC) recommends using soap and water or an alcohol-based hand sanitizer when soap is not available. If you have been in contact with potentially contaminated surfaces or food, ensure that your hands are cleaned properly to minimize any risk of infection.

3. Transmission by Flies:
There is limited evidence to suggest that small flies, such as houseflies, can transmit H. pylori. Flies can carry various pathogens on their bodies and in their feces, and while they are not a primary vector for H. pylori, they can contribute to the spread of other gastrointestinal infections. To reduce the risk of transmission, it is advisable to maintain good hygiene practices, such as keeping food covered, cleaning up spills promptly, and ensuring that waste is disposed of properly.

In summary, the prevention of H. pylori infection revolves around maintaining good hygiene practices. This includes proper handwashing techniques, using effective cleaning agents on surfaces, and being mindful of food safety. If you suspect you have been exposed to H. pylori or are experiencing gastrointestinal symptoms, it is important to consult a healthcare professional for appropriate testing and treatment. Regular medical check-ups and awareness of your health status can also play a crucial role in preventing infections.
