- you have HIV/ AIDS
- have lived in or visited malaria prone areas. You need to wait atleast a year if you have visited a country with malaria, or wait 3 years if you have lived in a country with malaria.
- if you lived in the United Kingdom for atleast 3 months from 1980- 1996, you might have variant Creutzfeld-Jacob disease (vCJD)...aka "mad cow" disease. So you will never be able to donate blood until further notice!...yaay!!!
- were born in, or lived in, Cameroon, Central African Republic, Chad, Congo, Equatorial Guinea,Gabon, Niger, or Nigeria, since 1977.
since 1977, received a blood transfusion or medical treatment with a blood product in any of these countries, or
had sex with anyone who, since 1977, was born in or lived in any of these countries. You might have HIV-O.
I found out the hard way... after feeling guilty one year, I walked myself to a blood drive, and after screening, I was told I couldn't donate blood because I had lived in England in the 80's for way more than 3 months. Also initially when i went those sheets used to state that if you had lived in or around the Congo...you couldn't give blood. I am not sure why, but I gather it has to do with Ebola or maybe just the hiv-O. So automatically I was ruled out for two reasons. Okay so the whimp in me was really happy:-), then the lady goes ati...'oh, but you can donate bone marrow'...I was like 'oh hhheeeeellll nooooooo!'
So there you have it! Donate blood and safe a life.
