SC disease‚ an autoimmune recessive condition‚ is an inherited abnormality of red blood cells. Affected children inherit two copies of an abnormal hemoglobin gene‚ one from each parent. For couples where both individuals carry one copy of the abnormal gene‚ described as having SC trait or being a carrier for SC disease‚ there is a 1 in 4 chance of future children being affected by the disease (?) From a biomedical perspective‚ a high potential for benefit from sharing research-generated SC disease

a cough in about 50%‚ while muscle ache occurs in about half. In adults‚ a fever is generally not present but it is common in infants and young children. The cough is usually mild compared to that accompanying influenza.

Because chronic carriers can live decades with none or few symptoms public health efforts are aimed at stopping transmission of HCV with “screening of potential carries to determine infection rates. The homeless have not been included in epidemiology studies of HCV due to their transient lifestyle making tracking and identification of carriers difficult. However data indicates that injection drug use accounts for the majority of cases of HCV among the homeless as compared to the general population
