Several schools around New Jersey are already feeling the impact of COVID-19 just days into the new school year.

Some schools that started with in-person lessons have now switched to remote learning after students tested positive for the virus or came into close contact with someone else who did.

Chatham High School is now moving to virtual learning for the rest of the week after a student who attended in-person class tested positive for COVID-19.

Superintendent Michael LaSusa said in a letter to parents that the case may be linked to a non-school event that took place over Labor Day weekend. LaSusa says that the district is working with local health officials and will soon be updating parents with plans for next week.

Over in Little Silver, a group of sixth graders have switched to remote learning until further notice after a student who attended Markham Place School this week tested positive for the coronavirus. The school says cleaning and disinfecting of exposed areas are complete.

Superintendent Michael Ettore wrote in a letter to parents, “The District is coordinating closely with local public health officials and following CDC, state, and local health department guidance to ensure the health and safety of our community.”

In East Brunswick, the Middlesex County Vocational and Technical Schools is moving to fully remote learning for the next two weeks after a freshman contracted the illness and attended in-person classes.

In a separate case in East Brunswick, the district superintendent says that several students came into contact with someone else who tested positive for the virus. Those students will attend school virtually until they are cleared by a doctor to return. None of those students have tested positive for the virus so far.

Middlesex County Vocational and Technical Schools is not part of the East Brunswick School System.
