Scabies Contagion: Are You Still Infectious? - Dermatology

More Info

---

Scabies, caused by the Sarcoptes scabiei mite, is a highly contagious skin condition characterized by intense itching and a rash. It spreads primarily through direct skin-to-skin contact, but it can also be transmitted via contaminated clothing, bedding, or furniture. Given your situation, it’s understandable to be concerned about the potential for contagion, especially since you and your daughter have been dealing with this condition for a month.

Firstly, regarding your question about whether you and your daughter are still infectious: if you have been consistently applying the prescribed topical treatment and following proper hygiene practices, the risk of contagion decreases significantly after 24 hours of effective treatment. However, if you are still noticing new red spots or symptoms, it may indicate that the treatment is not fully effective, or that there may be reinfestation or secondary infections occurring.

It’s important to note that the mites can survive outside the human body for a short period, typically up to 2-3 days. This means that if your friend came into contact with items that may have been contaminated, there is a potential risk of transmission. However, simply visiting your home for a day does not guarantee that they will contract scabies, especially if they did not have direct skin contact with you or your daughter.

As for your friend's precautionary measure of soaking in sulfur water, while sulfur has been traditionally used in some treatments for skin conditions, there is limited scientific evidence to support its effectiveness as a preventive measure against scabies. The best approach for your friend would be to monitor for any symptoms of scabies, such as itching or rash, and consult a healthcare provider if they develop any concerning signs.

To ensure that you and your daughter are no longer infectious, consider the following steps:
1. Continue Treatment: Ensure that you are following the treatment regimen as prescribed by your healthcare provider. If symptoms persist, consult your doctor for a follow-up evaluation and possibly a different treatment option.

2. Hygiene Practices: Wash all clothing, bedding, and towels in hot water and dry them on a hot cycle. Items that cannot be washed should be sealed in a plastic bag for at least 72 hours to kill any remaining mites.

3. Avoid Close Contact: Until you are certain that the infestation has been resolved, it’s advisable to limit close contact with others, especially those who are vulnerable, such as young children, the elderly, or immunocompromised individuals.

4. Monitor Symptoms: Keep an eye on any new symptoms for both you and your daughter. If new spots continue to appear or if itching worsens, it may be necessary to revisit your healthcare provider for further assessment.

5. Inform Close Contacts: It may be prudent to inform anyone who has had close contact with you or your daughter about the situation so they can be vigilant for any symptoms and seek treatment if necessary.

In conclusion, while the risk of contagion decreases significantly with proper treatment and hygiene, it’s crucial to remain vigilant and proactive in managing the condition. If you have any doubts about your treatment or symptoms, don’t hesitate to reach out to your healthcare provider for guidance.
