Study highlights importance of CDC COVID-19 mitigation strategies

A new US Centers for Disease Control and Prevention (CDC) Morbidity and Mortality Weekly Report (MMWR) on SARS-CoV-2 transmission at an overnight camp in Georgia found efficient spread of the virus among campers and staff while noting key steps to minimize the risk for SARS-CoV-2 introduction and transmission in camps were not strictly followed.

The camp adopted some mitigation steps found in CDC Suggestions for Youth and Summer Camps to minimize the risk for SARS-CoV-2 introduction and transmission to include cohorting of attendees by cabin and enhanced cleaning and disinfection. However, the camp did not require the 363 campers to wear masks, only the staff. Additionally, camp attendees engaged in a variety of indoor and outdoor activities that included daily vigorous singing and cheering, which might have contributed to transmission.

Settings, like multi-day, overnight summer camps, pose a unique challenge when it comes to preventing the spread of infectious diseases considering the amount of time campers and staff members spend in close proximity, says the CDC. Correct and consistent use of cloth masks, rigorous cleaning and sanitizing, social distancing, and frequent hand washing strategies, which are recommended in CDC’s recently released guidance to reopen America’s schools, are critical to prevent transmission of the virus in settings involving children and are our greatest tools to prevent COVID-19, concludes the CDC.

ON DEMAND: Business-impacting events such as severe weather, man-made disasters, and supply chain disruption are increasing in frequency and making impacts around the globe.

In today's rapidly evolving security landscape, organizations face an ever-growing array of disruptive events, security threats and risks. Traditional reactive approaches to security intelligence often leave businesses vulnerable and ill-prepared to anticipate and mitigate emerging threats that could impact the safety of their people, facilities or operations.
