Hi . It is understandable that you have concerns over sudden symptoms and it is good that you are seeking answers and information. I do want to note that we are not medical professionals and, for your safety, cannot offer medical advice over the internet. That said, transmission from what you describe is unlikely and this article from our editorial team goes into further detail on transmission: https://h-i-v.net/transmission. You mention concerns over symptoms and seroconversion, so I also want to share this article on early HIV infection and seroconversion symptoms and windows: https://h-i-v.net/symptoms/early-stage. Of course, the only way to be certain is through testing. This article discusses the various tests, including the testing window for each: https://h-i-v.net/test-types. I hope this information is helpful and please feel free, if you like, to keep us posted on how you are doing and to ask additional questions. Best, Richard (Team Member)
