Coronavirus 9 northern states to close schools for 30 days

I'm not aware of any information that suggests 9 northern states will close schools for 30 days due to the coronavirus. In fact, the decision to close schools is typically made at the local or state level, and it's not a blanket decision that would apply to all states.

That being said, some states and localities have taken measures to close schools or implement remote learning due to the pandemic. For example, in March 2020, many schools in the United States closed due to the pandemic, and some states, such as California, New York, and Illinois, implemented extended school closures.

It's possible that you may be referring to a specific state or region that has taken measures to close schools, but without more information, it's difficult to say for certain. If you could provide more context or clarify which states you are referring to, I may be able to help you better.

It's also worth noting that the situation with the coronavirus is constantly evolving, and decisions about school closures are often made on a case-by-case basis. It's important to stay informed through reputable sources, such as the Centers for Disease Control and Prevention (CDC) and local health authorities, for the most up-to-date information on the pandemic and any related school closures.
