Donating blood is a 100 percent disease-free activity. Each needle used in the procedure is sterile and is disposed of after a single use. Thus, it is not possible to contract HIV, the virus that causes AIDS, or any other disease, by donating blood. In general, people in good health who weigh at least 110 pounds may donate a unit of blood as often as every eight weeks. There are many places.
Bloodmobiles travel to high schools, colleges, churches, and other community organizations.
People can donate at community blood centers and hospital-based donor centers, and many people donate at blood drives at their workplace.
