Nursing homes — once the epicenter of the pandemic in New Jersey — reported infection levels began to decline quickly last winter, once vaccines were widely available to residents and staff. That trend continued through this spring, mirroring the virus’s impact on the community at large. In May state regulators allowed family and friends to visit residents again, albeit with masking and other protocols, particularly when the individuals involved are not immunized.
But the expanding presence of the delta variant — which spreads twice as effectively as the original form of the virus — recently changed the trajectory of the disease in long-term care facilities. National nursing-home data indicates a low point for new cases among residents and staff in mid- to late June, but diagnoses have escalated quickly since then. By the week ending July 18, the most recent for which figures are available, cases among residents had grown 124% and staff cases increased 184% over three weeks.
