Regarding viral or bacterial infections (I apologize, but I have some more questions to ask the doctor)?

Hello, doctor.
I apologize for bothering you, but I have a question.
I'm not sure if it was an insect bite or something else that bit me.
I also wonder if it could be possible to contract bacteria or viruses (such as HIV, Hepatitis B, or Hepatitis C) through playing volleyball, since volleyballs can be dirty and may have blood on them.
I've been experiencing headaches and dizziness, but those symptoms have improved.
I forgot to mention that after playing volleyball, I had some nausea for a few days, but now the feeling is only slight.
Up until the sixth day after playing, the wound has not shown any signs of swelling or pain.
I also visited a medical clinic and had blood and urine tests done.
However, I understand that there is a window period for viral infections, and it typically takes about three months for tests to show results.
I'm very worried and anxious, which is why I'm reaching out to you.
I've been quite concerned these past few days, and I hope you can provide me with some answers.
Thank you, doctor.

Hello: Perhaps I didn't explain clearly, which made you worry.
Let me clarify in another way.
Hepatitis B and C are bloodborne infectious diseases, as they are transmitted directly through blood exposure and are not spread by insects.
For instance, if a mosquito bites a person with Hepatitis B and then bites a healthy person, the healthy person will not contract Hepatitis B (there have been no documented cases of such transmission worldwide).
HIV is a sexually transmitted infection that spreads through sexual contact, and it can also be transmitted directly through blood exposure; however, it is not transmitted by insects.
Therefore, if a mosquito bites an HIV-positive person and then bites a healthy person, it should not transmit HIV (no such transmission has been documented to date).
Based on the situation you described, the likelihood of a general infection is very low, as it has been six days since the injury, and there is no swelling or pain at the wound site.
As for the possibility of contracting specific viruses (such as dengue fever or Japanese encephalitis), it is also quite low, even though the incubation periods for these diseases range from about 5 to 21 days, as there are currently no outbreaks of these specific diseases.

More Info

Your concerns regarding the potential for viral and bacterial infections after playing volleyball, especially in relation to contact with blood or other bodily fluids, are understandable. It's important to clarify a few key points regarding the transmission of infections through casual contact with sports equipment, particularly in a scenario where there may be open wounds involved.

First and foremost, the risk of transmitting serious viral infections such as HIV, Hepatitis B, or Hepatitis C through contact with a volleyball that may have blood on it is extremely low. HIV, for example, is a virus that does not survive long outside the human body. It typically becomes inactive within minutes once exposed to air. Similarly, Hepatitis B and C viruses also have limited survival outside the body, and their transmission generally requires direct contact with infected bodily fluids in significant quantities, such as through open wounds or mucous membranes.

In your case, if you had an open wound and came into contact with a volleyball that had blood on it, the risk of transmission would still be minimal unless the blood was from an infected individual and there was a significant amount of blood that directly entered your wound. The likelihood of encountering such a scenario during a casual game of volleyball is quite low.

Regarding your symptoms of headache, dizziness, and nausea, these could be attributed to a variety of factors, including dehydration, fatigue, or even anxiety about the potential for infection. It's good to hear that you have consulted with a healthcare provider and undergone blood and urine tests. If those tests did not indicate any immediate issues, it is a positive sign. However, as you mentioned, certain viral infections can have a window period during which they may not be detectable. For HIV, this window period can be up to three months, so if you remain concerned, it may be advisable to follow up with your healthcare provider for further testing after this period.

In terms of wound care, it is essential to keep any cuts or abrasions clean and covered to prevent bacterial infections. If you notice any signs of infection, such as increased redness, swelling, warmth, or pus, you should seek medical attention promptly.

In conclusion, while your concerns are valid, the risk of contracting serious viral infections through casual contact with a volleyball is very low. Maintaining good hygiene practices, monitoring your health, and consulting with healthcare professionals as needed will help alleviate your worries. If you continue to experience symptoms or have further concerns, do not hesitate to reach out to your healthcare provider for additional guidance and support.
