Those who have this "Rhesus" factor on their red blood cells are considered Rh positive. Those who lack the factor are called Rh negative. Thus every person is either Rh positive or Rh negative while also belonging to one of the ABO groups. Approximately 85% of the population is Rh positive.

Which Blood Types Do Mosquitoes Prefer? People with Type O blood are more than universal donors. They're also “tastier” to mosquitoes.
