The first death of an infant from the coronavirus was reported in the state of Illinois of the USA on Saturday.
The baby, younger than one year, in Chicago tested positive for the virus, said officials.
"There has never before been a death associated with COVID-19 in an infant," said Illinois Department of Public Health Director Dr Ngozi Ezike. "We must do everything we can to prevent the spread of this deadly virus."
Ezike said an investigation is underway to determine the cause of death.
