Half of the 22-member majority Democrats in the state Senate have doubts about the way Gov. Ned Lamont is moving toward the reopening of the state and said that if tougher health guidelines aren’t adopted, the state could quickly increase the infection rate after the first phase of the governor’s reopening occurs on May 20.

In a letter to the governor, the 11 lawmakers warned that while the hospitalization rate has been going down steadily, it is merely one indicator, while the state’s testing rate could be inadequate in detecting outbreaks. They said that random samples of people in both cities and suburbs are needed, as well as grocery shoppers, hospital workers and essential manufacturers that have been operating during the pandemic.

They asked that the governor provide more guidance for businesses, including the creation of a team of specialists available by phone to discuss individual strategies to reduce the possible spread of the coronavirus.

“The decisions you have made regarding social distancing and other measures have greatly reduced the disease burden in the state,” said the senators, led by Senate President Pro Tempore Martin M. Looney of New Haven, Majority Leader Bob Duff and Sen. Saud Anwar of South Windsor, a pulmonologist. “But it would be a great loss to everyone to reopen the state without having at least some of our evidence-based protections in place. We could lose all the success that has already been achieved at great sacrifice.”

Lamont’s office did not immediately respond with a request for comment. The governor has scheduled his daily briefing for reporters for 2 p.m.
