Can You Catch Chickenpox After Scabs Form? the Risks

Chickenpox can be transmitted through the crusts of the blisters?

Once chickenpox lesions have crusted over, the risk of transmission is significantly reduced.
However, it is still possible to contract the virus from someone who has chickenpox, especially if you have not previously had the infection or been vaccinated against it.
If your boyfriend's lesions are completely crusted and he is no longer exhibiting other symptoms, the likelihood of you contracting chickenpox from kissing him is lower, but not entirely eliminated.
It is advisable to monitor for any symptoms and consult a healthcare provider for further guidance.

The chances are lower.
If you have had chickenpox, you have immunity and don't need to worry.

More Info

When it comes to chickenpox (varicella), understanding the timeline of contagion is crucial for preventing the spread of the virus. Chickenpox is caused by the varicella-zoster virus (VZV), and it is highly contagious. The contagious period begins about 1 to 2 days before the rash appears and lasts until all the blisters have formed scabs.
Once the scabs have formed, the risk of transmission significantly decreases. According to the Centers for Disease Control and Prevention (CDC), individuals with chickenpox are considered no longer contagious once all the lesions have crusted over, which typically occurs about 5 to 7 days after the rash first appears. Therefore, if your boyfriend has developed scabs and they are healing properly, he is likely no longer contagious.

However, it is important to note that chickenpox can still be transmitted through respiratory droplets or direct contact with the fluid from the blisters before they crust over. If you have never had chickenpox or have not been vaccinated against it, you are at risk of contracting the virus if you come into contact with someone who is contagious.

In your case, since your boyfriend has scabs and is reportedly feeling better, the risk of you catching chickenpox from him is low. However, if you have not had chickenpox or the varicella vaccine, it is still advisable to monitor for any symptoms of chickenpox, which typically include fever, fatigue, and the characteristic itchy rash that progresses from red spots to fluid-filled blisters and then to scabs.

If you are concerned about your risk, consider consulting with a healthcare provider. They may recommend a varicella titer test to check for immunity to the virus. If you are found to be non-immune, your healthcare provider may discuss vaccination options with you, especially if you have been exposed to someone with chickenpox.

In summary, while the risk of transmission after scabs have formed is significantly reduced, it is not entirely zero if there were any lingering lesions or if the person was still within the contagious period. Always prioritize good hygiene practices, such as handwashing, and avoid close contact with individuals who are ill, especially if you are unsure of your immunity status. If you have any symptoms or concerns, seeking medical advice is always a prudent step.
