Hello
You had gen4 HIV test 0.34 , later on after 5 days negative 0.38 . After 4 hours of ORAL SEX there was
oral thrush , anxiety , stress,
depression , itching skin , you were also taking antibiotics at the time of this episode .
I read your query and doubts , all .
I am writing this answer that you had ONLY ORAL SEX , so answer is based only on this and as far as my experience and studies reports:
Oral sex is a much less efficient mode of transmission of HIV infection.
Although HIV can be isolated typically in low titers from saliva of a small proportion of INFECTED individuals , there is NO CONVINCING EVIDENCE that saliva can transmit HIV infection , either through kissing ( even deep ) or oral sex exposures.
Saliva contains endogenous
antiviral factors ;among these factors ,HIV-specific
immunoglobulins of Ig A, Ig G and IgM isotypes are detected readily in salivary secretions of HIV infected individuals ( now NOTE down that even HIV infected can't transmit HIV infection by oral route , but in your case status of girl was no known) .
So you are HIV free .
Antibodies to HIV begin to appear within 2 weeks of infection and development of detectable antibodies is not more than 3 months ( so get in ELISA test for confirmation ).
White coating on the tongue may be due to fungus or
candidiasis .
In my opinion
consult a dermatologist and get his opinion.
I don't recommend you any test for HIV but since you are under so stress, so I advise, this .
Good luck.
