The Hawaii Department of Health said it is investigating a report of acute pediatric hepatitis of unknown origin in a child under 10 living on Maui.
The DOH said the child was hospitalized for several days with abdominal pain and a fever in late April.
“A thorough medical investigation has been completed and there remain a number of outstanding lab test results,” the DOH said in a statement. “At this time, no cause has been determined. The DOH is working with the Centers for Disease Control and Prevention to identify the cause of the hepatitis case.
The CDC is investigating more than 100 cases of childhood hepatitis with no known cause that have been reported in 24 U.S. states and Puerto Rico, according to Bloomberg News, including five deaths.
On April 21, the CDC issued a nationwide health alert regarding a group of nine children identified with hepatitis of unknown origin in Alabama, all of whom were previously healthy. The CDC said none of these children, ages 1 to 6, had COVID-19.
The CDC has asked all physicians to be on the lookout for symptoms and to report any suspected cases of hepatitis of unknown origin to their local and state health departments.
