Can this lead to hepatitis B, hepatitis C, syphilis, or tetanus?

Hello, Doctor.
A few days ago, while I was browsing a kitchenware store in a department store, I accidentally scraped my hand on a product displayed by the store (a metal stirring stick with a gear-shaped end).
At that moment, I felt a brief sting, but then I didn't feel anything afterward.
I couldn't find any signs of a scratch (there was no bleeding or visible mark).
I sprayed a large amount of alcohol on the area where I felt the sting, and there was no sensation of irritation from the alcohol, and throughout the day, washing my hands didn't cause any stinging sensation, so I thought I wasn't injured.
However, the next day, I noticed a scratch in that area, with some pale pink tissue visible, and washing my hands caused stinging.
It took another two days for it to scab over.
I am currently four months pregnant, and I am extremely worried about the possibility of contracting hepatitis B, syphilis, or tetanus.
If the stirring stick had scraped other customers, I cannot speculate whether they carry these infectious diseases.
It seems that I cannot get immediate blood test results at this stage, so I would like to ask the doctor if my concerns are unfounded given my situation.
Thank you, Doctor.

Hello: While I cannot say that the situation you mentioned is impossible, the probability is extremely low (you can think of it as being even less likely than being struck by lightning).
The reason is that bacteria or viruses such as hepatitis B and syphilis can survive outside the body for at most a few hours.
Therefore, unless the same stirring stick was used on another customer within a few hours, and that customer happened to be highly infectious, the scenario you described could occur.
However, if you were not bleeding at the time, the chance of being infected through blood is also very low.
Tetanus is generally more of a risk when injured by dirty instruments, and it is unlikely that a stirring stick from a department store would carry tetanus bacteria.
If you are still concerned, you can visit an infectious disease clinic for regular follow-up, but I believe that, in terms of risk, it is not really necessary.
This is for your reference.

More Info

Based on your description, it seems that you experienced a minor injury from a metal object in a public place, which has understandably raised concerns about potential infections such as Hepatitis B, Hepatitis C, Syphilis, or Tetanus. Let's break down your situation and address your concerns regarding these infections.

Risk of Hepatitis B and C
Hepatitis B and C are primarily transmitted through blood-to-blood contact, sexual contact, and from mother to child during childbirth. In your case, the risk of contracting Hepatitis B or C from a minor scratch caused by a metal object is extremely low, especially if there was no visible blood involved. The fact that you did not see any bleeding or significant injury further reduces the likelihood of transmission.
However, it is important to note that Hepatitis B can survive outside the body for a period of time, but the risk of transmission through a non-bleeding scratch is minimal. Hepatitis C, on the other hand, is less stable outside the body and typically requires direct blood contact for transmission. Given that you did not have any open wounds or bleeding, your risk remains very low.

Risk of Syphilis
Syphilis is primarily transmitted through direct contact with syphilis sores during sexual activity. It is not transmitted through casual contact or through objects like the one you described. Therefore, the risk of contracting syphilis from the metal object is negligible, especially since there was no direct contact with any sores.

Risk of Tetanus
Tetanus is caused by a bacterium called Clostridium tetani, which is commonly found in soil, dust, and animal feces. It typically enters the body through deep puncture wounds or cuts. Since your injury was minor and did not involve a deep puncture, the risk of tetanus is low. However, if you have not had a tetanus booster in the last 10 years, it is advisable to consult your healthcare provider about getting a booster shot, especially if the injury had been more severe.

General Recommendations
1. Monitor the Injury: Keep an eye on the scratch for any signs of infection, such as increased redness, swelling, warmth, or pus. If you notice any of these symptoms, seek medical attention.

2. Consult Your Healthcare Provider: Since you are pregnant, it is essential to discuss any concerns with your healthcare provider. They can provide personalized advice and may recommend blood tests if necessary.

3. Vaccination: Ensure that you are up to date with your vaccinations, including the Hepatitis B vaccine if you have not received it. Pregnant individuals are often advised to get vaccinated against Hepatitis B to protect both themselves and their baby.

4. Practice Good Hygiene: Continue to wash your hands regularly and keep any wounds clean and covered to prevent infection.

Conclusion
In summary, your concerns about contracting Hepatitis B, C, Syphilis, or Tetanus from the incident you described appear to be largely unfounded, given the nature of the injury. However, it is always best to consult with your healthcare provider for peace of mind and to ensure that you are taking the appropriate steps to protect your health during your pregnancy.
