Teaneck officials are calling for all residents to self-quarantine and only leave their residences for food and medicine as the township grapples with the most coronavirus cases in Bergen County.

Mayor Mohammed Hameeduddin called Teaneck “ground zero” Saturday and urged residents to self-quarantine as the number of cases surged to 18. Some 60 percent of Bergen County's 31 confirmed virus infections are in the township, which has a population of more than 41,000. The call for self-quarantine came after Hameeduddin consulted with the township's manager and emergency management coordinator.

“There are people that don’t understand that this is something we haven’t seen since World War II,” he said. “We don’t have enough test kits, every day more and more people will be getting sick.”

Hameeduddin said residents should go out only if they "absolutely have to." He said a townwide quarantine was the best way to stop the virus from spreading.
