Check a few of our commonly asked questions
AIDS and HIV
You must not donate blood if:
You have AIDS or HIV, the virus which causes AIDS.
You suspect you may have been exposed to HIV.
You have unexplained weight loss, persistent night sweats, fever, diarrhoea or swollen glands. These symptoms could be due to HIV infection or another serious illness. Please see a doctor.
You are at risk of HIV infection due to high-risk activities you do presently or in the past.
High-risk activities include the following:
Having casual sex
Having sex with another man (if you are a male)
Having sex with multiple partners
Having sex with prostitutes or commercial sex workers
Having sex with someone who has HIV/AIDs
Took or injected yourself with addictive drugs
Working as a prostitute or commercial sex worker
It is important not to donate blood if you have been exposed to the HIV virus from high-risk activities. There is a window period in the early stage of HIV infection, lasting several weeks to months, where you may feel well and test negative for the virus, but can still pass it to someone else.
Note: The term "sexual activity" means any of the activities below whether or not a condom or other protection was used:
Vaginal sex (contact between penis and vagina)
Oral sex (mouth or tongue on someone’s vagina, penis, or anus)
Anal sex (contact between penis and anus)
Cold, flu or sore throat
You should not donate blood if you have an upper respiratory tract infection, such as cold, flu, sore throat or any other symptoms of infection.
You should wait for 1 week after recovery, as it may be harmful to you and the recipients if you donate blood when you have an infection. If you also have fever, the waiting period is 4 weeks.
