This week, MMWR published seven reports. One looks at how COVID-19 spreads within households. Two reports underscore the importance of counseling pregnant women about their risk for severe COVID-19 illness and the potential risk for preterm birth. Another report looked at possible workplace exposures to COVID-19 and how those who telework are less likely to have infection. Two reports published this week focus on the Hopi Tribe in Arizona - one report detailing an outbreak among the tribe and another report on the development of a community surveillance program. The last report highlights the success of a county jail in using network science to reduce the spread of COVID-19 among detained people and staff.
