Doctors at the Rambam Medical Center in Haifa, Israel, found three premature babies on Thursday that were carrying the swine flu virus.
The H1N1 virus remained dormant in all three infants, who were isolated from the other newborns at the facility. The hospital is conducting an investigation to determine the source of the virus, the Times of Israel reports.
Two Israelis died as a result of swine flu this winter. The first, a three-year-old boy in Petah Tikva in mid-January, was the first swine flu death in the country since 2009. A 28-year-old woman with the flu in Beersheba died two weeks later.
Following the second death, a health official called on the public to stay away from emergency rooms unless there was no other way to obtain medical attention, according to the Times of Israel.
Officials with the Health Ministry said in January there while there are no special safeguards prepared against the swine flu in Israel, the current flu vaccine includes immunization against H1N1.
Patients with chronic illnesses, pregnant women, the elderly and children are at high risk of complications from contracting the disease, the Times of Israel reports.
Hundreds of cases of the H1N1 virus were recorded in the West Bank in this year. At least 10 people died as a result of the illness, Israel Radio reports.
