What is hematology? Hematology is the study of blood and blood disorders. Hematologists and hematopathologists are highly trained healthcare providers who specialize in diseases of the blood and blood components. These include blood and bone marrow cells. Hematological tests can help diagnose anemia, infection, hemophilia, blood-clotting disorders, and leukemia.
Roseola is a viral illness that usually affects children between the ages of six months and two years. It is typically marked by several days of high fever, followed by a pinkish-red flat or raised rash that appears on the child's torso and spreads over the body as the fever breaks.
Who is most at risk of a roseola infection? Roseola usually affects children from six months to three years of age. Although it is not common, roseola can sometimes occur before six months of age. Newborn babies are not at high risk for roseola because of the antibodies they receive from their mothers.
