Hello: 1.
If he has genital warts, will I get infected if I touch an apple? --> No.
2.
Is it true that other sexually transmitted infections (STIs) are more likely to be transmitted through bodily fluids, while only genital warts can be transmitted through skin contact? --> Yes, the risk of transmission through direct skin contact is higher for genital warts.
3.
If my sister washes the apple before eating it, does that eliminate the risk of genital warts? --> Yes.
4.
If my sister washes the apple on a bowl that hasn't been washed yet, could that leave STIs on the bowl? I washed the bowl an hour later, and water splashed on my face.
--> No, there is no risk of transmission.
I'm worried that if the water splashed on my face, and I have acne wounds, could I get infected if it splashed into my mouth, eyes, or nostrils? --> No.
Wishing you good health.

When it comes to concerns about the transmission of sexually transmitted diseases (STDs) through contaminated food items, such as apples, it is essential to understand the nature of these infections and the modes of transmission.
1. Transmission of STDs through Food: Most STDs, including HIV, gonorrhea, chlamydia, and syphilis, are primarily transmitted through sexual contact, which involves the exchange of bodily fluids such as semen, vaginal secretions, and blood. The likelihood of contracting an STD from food, such as an apple, is extremely low unless there is direct contamination with infected bodily fluids. If your uncle was intoxicated and potentially contaminated the apple with his bodily fluids, the risk of transmission would still be minimal.
2. Specific Concerns about HPV (Warts): Human Papillomavirus (HPV), which can cause genital warts (often referred to as "cauliflower" due to their appearance), is primarily transmitted through skin-to-skin contact during sexual activity. While HPV can survive on surfaces for a short period, the risk of transmission through inanimate objects, such as fruit, is very low. If you were to touch an apple that had been contaminated with HPV, the likelihood of contracting the virus is minimal, especially if you do not have any open wounds or mucous membranes in contact with the contaminated surface.

3. Washing the Apple: Washing the apple before consumption significantly reduces the risk of any potential contamination. Washing fruits and vegetables is a good practice to remove dirt, bacteria, and any potential contaminants. If your sister washed the apple thoroughly before eating it, this would further mitigate any risk of infection.

4. Concerns about Cross-Contamination: If your sister washed the apple in a bowl that had not been cleaned after your uncle used it, there is a theoretical risk of cross-contamination. However, the risk remains low. If the bowl had any residual bodily fluids, the likelihood of those fluids being infectious after washing the apple is minimal. Additionally, the risk of infection through splashes or contact with your face, especially if you have acne or open wounds, is also very low. STDs generally require direct contact with mucous membranes or open wounds for transmission.

5. General Recommendations: If you have concerns about potential exposure to STDs, it is always best to consult a healthcare professional. They can provide personalized advice and, if necessary, testing for STDs. It is also important to maintain good hygiene practices, such as washing hands and food items, to minimize any risk of infection from various sources.

In summary, while your concerns are valid, the risk of contracting an STD from contaminated apples, especially after washing them, is extremely low. The primary mode of transmission for STDs remains sexual contact, and casual contact with contaminated surfaces or food items poses a minimal risk. If there are any lingering concerns or symptoms, seeking medical advice is the best course of action.
