How is HIV transmitted?

The virus is passed on to another person through infected blood like blood stained needles/medical instrumentations, sexual contacts between casual acquaintances or with strangers/multiple partners, or partners of infected OFW, sharing of needles among drug users or accidental needle pricking or trauma among health professionals. HIV infected individuals can infect unsuspecting contacts because of their normal looking physique. Spread of the disease happens before identification of the disease is the most treacherous of all possibilities.
