The risk of severe COVID-19 within households of school employees and school-age children.
Across the United States, school districts are grappling with questions of whether and how to reopen elementary and secondary schools in the 2020-21 academic year. Using pre-pandemic household data, the authors examined how often persons at risk of severe coronavirus disease 2019 (COVID-19) were connected to schools, either as employees or by living in the same households as school employees or school-age children.

Longitudinal, strain-specific Staphylococcus aureus introduction and transmission events in households of children with community-associated meticillin-resistant S aureus skin and soft tissue infection: a prospective cohort study.
This prospective cohort study examined methods of transmission for methicillin-resistant Staphylococcus aureus (MRSA) in households with otherwise healthy children who have a MRSA infection. From 2012-2015 households in St. Louis with children who had a community-acquired MRSA skin and soft-tissue infection were longitudinally tracked. Children with other health issues were excluded. A baseline visit was conducted at the index patient’s primary home, followed by four quarterly visits over 12 months. With each visit, an interview and serial cultures were collected. Molecular typing was done of those samples to determine the distinct S aureus strain. MRSA recipients were most likely to live in a rental situation, and were more likely to share a bedroom with a strain-colonised individual. The most likely transmission source was shared bath towels. Pets were often recipients, but rarely the sole transmission source. Frequent handwashing decreased the likelihood of novel strains being introduced into the house and emphasizes the importance of hand hygiene.

Remembering the benefits of vaccination.
This commentary discussed the issue of vaccination and tightening exemptions for school entry. The author pointed out that events show that the success of vaccines can be fragile, as the measles cases associated with Disneyland were preceded by 644 cases in 2014. And 2012 saw more than 40,000 cases of pertussis, the largest number since 1960. These events provided a dramatic reminder that vaccines remain an important and necessary public health tool.

Group A streptococcal bacteremia without a source is associated with less severe disease in children.
The authors analyzed characteristics of 86 Group A streptococcal bacteremia cases at Boston Children's Hospital from 1992 to 2012. They found that children with bacteremia without a source (30% of cases) were less likely to have severe disease than children with focal infections.

Environmental drivers of the spatiotemporal dynamics of respiratory syncytial virus in the United States.
The authors examined the association between environmental variables and state-specific measures of respiratory syncytial virus (RSV) seasonality. They found that states with low mean vapor pressure and the largest seasonal variation in potential evapotranspiration tended to experience biennial patterns of RSV activity, with alternating years of "early-big" and "late-small" epidemics. Their results successfully connected environmental drivers to the epidemic dynamics of RSV; however, the results do not fully explain why RSV activity begins in Florida, one of the warmest states, when RSV is a winter-seasonal pathogen.
