Hello and welcome to e health forum. â â
The âwindow periodâ is a term used to describe the period of time between HIV infection and the âproduction of âantibodies.â Once a virus, is detected by the immune cells of the body, antibody synthesis is initiated and it persists âââas long as the virus is active in the body. â
ââ97% of normal individuals with a good immune system, produce antibodies within 4-12 weeks and the ââremaining ââ(3%) might produce the antibodies, around or after 6 months. â
It is extremely rare for a person to take any longer than 6 months to develop detectable antibodies.â
In case you were infected in reality, then the antibodies would be in higher titres and you would have âhad severe âmanifestations of HIV infection by now. â
Your HIV test done after 1 year after exposure is conclusive and indicate that you do not have HIV.â
With regard to your symptoms , they are most likely due to allergy related causes and not due to HIV.
You might consult with your doctor who can examine you and provide proper treatment of your condition.
