New York to alter mask guidelines for schools Monday WKBW and last updated 2021-06-04 16:52:27-04 ALBANY, N.Y. (WKBW) â New York announced it plans to alter mask guidelines for schools on Monday. New York State Health Commissioner Dr. Howard Zucker issued a letter to CDC Director Rochelle P. Walensky about the state's concern over the consistency of the CDC guidance on mask wearing between schools and summer camps. For K-12 schools the CDC currently recommends a requirement for âconsistent and correct use of well-fitting face masks with proper filtration by all students, teachers, and staff". Zucker says it does not make a distinction between indoors versus outdoors and does not address those who are vaccinated.
