Objectives: To show that circulation of SARS-COV-2 in nursing homes in France can come from staff as well as residents' families, whether they are known or not to have had COVID-19.
Methods: This study reports a screening campaign of asymptomatic staff working in elderly nursing homes in Paris where the virus had been circulating actively in March and April 2020.
Results: Before the screening campaign, the rate of symptomatic COVID-19 was 23.
We developed a real-time High Resolution Melting PCR to identify the new Swedish variant of Chlamydia trachomatis ncCT. Of 1191 urogenital specimens C. trachomatis-positive by an omp1 real-time PCR, collected in France in 2007-2008, 1128 gave an interpretable profile corresponding to the wild-type strain; no nvCT was found.
