COVID 19 - The Coronavirus
The CDC (Centers for Disease Control & Prevention) and the New Hampshire Department of Health & Human Services (DHHS) provide continuous updates regarding Covid-19 which are available on their websites (links provided below). The DHHS provides data specific to New Hampshire in regards to cases and potential cases of Covid-19. The DHHS provides guidance based on CDC best practices and recommendations.
The best defense for combating the spread of viruses, including Covid-19, is 1) knowing how to avoid being exposed and what to do if someone is exposed (or potentially exposed), and 2) steps to take if someone is ill (or potentially ill) with the virus.
