The double infection was first identified in a woman who went into labor this week at Rabin Medical Center in Petah Tikva. According to the hospital, the young mother, who is not vaccinated against either pathogen, is feeling well and is expected to be discharged from the hospital later Thursday.

The Health Ministry is still examining the case, which was relatively mild, and is yet to determine whether a combination of the two viruses causes more severe illness.

Health officials estimate many other patients have also come down with both bugs but have not been diagnosed.
