It is said the disease is not spread by body fluids like saliva, tears or sweat or kissing and not even by mosquito bite ( reference youth focus article Kuensel ). It seems HIV is primarily spread through unprotected sex and blood transfusion. And yet mosquito bite does not spread HIV though blood is involved if a mosquito bites a HIV person and then bites a non- HIV person.
What could be the difference between other body fluids and genital fluids.? And what is the difference between HIV blood passed on through direct transfusion and through mosquito ?
How does a human body compartmentalise a disease that it is contagious only through direct genital to genital contact and blood transfusion in more volume than what a mosquito can pass on ? Are world authorities on HIV being totally honest or declaring convenient statements to protect social life of HIV patients ?
