Top in ID: Poliovirus detected in NYC; Lyme disease vaccine shows promise

Health officials said they detected poliovirus in New York City sewage samples. It was the top infectious disease story last week.

The findings suggest the virus is circulating locally, but the samples were not genetically related to other positive samples recently collected in Rockland and Orange counties, which were linked to a specific vaccine strain. The CDC recommends children receive four doses of the vaccine by age 6 years.

Another top story was about Pfizer and Valneva announcing the phase 3 trial of their Lyme disease vaccine candidate, VLA15.
