Officials say admissions to hospitals in Lincs have fallen after patients suffering with norovirus were asked to stay away due to bed shortages.
People with the winter sickness bug were being asked to stay away
Hospitals in Lincoln, Boston and Grantham remain on red alert because of increased pressure on services.
Managers have thanked health organisations and the public for working together to ease the pressure.
Hospital staff have been working extra shifts and extra beds have been opened to help ease the crisis.
Ward rounds have also been increased to identify patients suitable for discharge.
The United Lincolnshire Hospitals NHS Trust said it is still experiencing pressures and people should continue to use A and E in serious cases.
The trust said there had been a 20% increase on the level of emergency admissions.
People suffering from the winter sickness bug have been asked to stay at home and use NHS Direct for advice.
