Many respiratory virus illnesses peak during the winter due to environmental conditions and human behaviors. COVID-19 has peaks in the winter and also at other times of the year, including the summer. This is driven in part by new variants and decreasing immunity from previous infections and vaccinations.
CDC's respiratory virus guidance has steps you can take to protect yourself and others from COVID-19 this summer.
In a new study published in JAMA Network Open, researchers have created a dataset and data visualization dashboard to evaluate the effectiveness of state and territory-level policies enacted to reduce the severity of COVID-19's impact on older people served by home health care agencies and nursing homes.
The authors found many policies within states and territories did not correspond with reductions in community or nursing home-level COVID-19 burden (i.e. number of cases and mortality counts). This suggests that policy effectiveness may depend on implementation and compliance. The study also found that policies focused less on home health care agencies compared with nursing homes, despite both settings serving vulnerable older populations.
JAMA Network Open has published a new study showing that, from April 1, 2020, to February 27, 2023, in California, an estimated 146,210 COVID-19 cases were averted by vaccination in teens aged 12 to 15 years, representing a 37% reduction.
