From the National Institute of Health:
EARLY SYMPTOMS OF HIV INFECTION If you are like many people, you will not have any symptoms when you first become infected with HIV. You may, however, have a flu-like illness within a month or two after exposure to the virus. This illness may include
Fever
Headache
Tiredness
Enlarged lymph nodes (glands of the immune system easily felt in the neck and groin)
These symptoms usually disappear within a week to a month and are often mistaken for those of another viral infection. During this period, people are very infectious, and HIV is present in large quantities in genital fluids. http://www.niaid.nih.gov/factsheets/hivinf.htm
In short, the tests given prior to deployment PROVE how concerned the military is with their walking blood supply.
Also, the promiscuity of gays AND their unbelievable willingness to find and engage in risky sex in every location means that they could be infectious with a month of deployment.
AND WE HAVEN'T even considered that the Gays are infamously infected with a host of other diseases that are not even checked for.....to include other blood-borne pathogens.
Thanks for the ping!
