PITTSFIELD — Berkshire Health Systems has raised its respiratory illness alert level to yellow, or moderate, amid a growing spike in illness in the community.

As the holiday season comes to a close, flu cases are spiking across the state, prompting local health care providers to remind residents to wash hands, stay hydrated and stay home when feeling unwell.

Under the new regulations, which go into effect as of 7 a.m. Thursday, all BHS staff must wear a mask when in direct contact with patients. In addition, any patients with symptoms should wear a mask, and visitors who have any respiratory illness symptoms are asked to postpone their visits, if possible.

“Respiratory illnesses have risen significantly in the community, and these changes are being implemented in order to help protect our patients, visitors and staff from the whole host of respiratory viruses circulating at this time of year, especially influenza, COVID-19, and RSV,” said Dr. James Lederer, chief medical officer/chief quality officer for BHS, in a prepared statement. “Masking, regular hand washing, and social distancing are all key factors in helping to prevent the spread of these very harmful viruses, and we will be vigilant in our efforts to combat these illnesses.”

Lederer said last week that the community has seen a "dramatic increase" in flu in recent weeks.

The color-coded system is in effect at Berkshire Medical Center, Fairview Hospital, North Adams Regional Hospital and all outpatient centers, including BHS physician practices.

Signage will be posted at all facilities, the BHS website will be updated regularly to reflect the current tier, and masks will be readily available at all facilities.
