Herd immunity is a key concept for epidemic control. It states that only a proportion of a population needs to be immune - through overcoming natural infection or through vaccination - to an infectious agent for it to stop generating large outbreaks. A key question in the current COVID-19 pandemic is how and when herd immunity can be achieved and at what cost. Herd immunity is achieved when one infected person in a population generates less than one secondary case on average, that is, the average number of persons infected by a case dropping below 1 in the absence of interventions. Taking these considerations into account, there is little evidence to suggest that the spread of SARS-CoV-2 might stop naturally before at least 50% of the population has become immune. With flu pandemics, herd immunity is usually attained after two to three epidemic waves, each interrupted by the typical seasonality of influenza virus and more rarely by interventions, with the help of cross-protection through immunity to previously encountered influenza viruses, and vaccines when available

The list of New Jersey school districts asking the state to let them start the school year with all-virtual classes is growing as local officials reconsider their plans in the wake of Gov. Phil Murphy’s announcement that the state is revising its reopening guidelines. Murphy said Wednesday the state’s nearly 600 districts can ask to delay the start of in-person classes if they can prove to the state Department of Education that they can’t meet the social distancing and safety guidelines released by the state in June. Students in all districts continue to have the option of choosing all-remote learning at home, even if their school is holding in-person classes, under the state’s guidelines. Merchantville School's Re-opening plan was approved by the Board of Education on July 28th and the completed plan is here. 

According to WHYY, New Jersey reported another 518 cases of coronavirus on Friday, September 11th, bringing the cumulative total over the last six months of the pandemic to 195,888 positive cases. The state also reported another nine deaths related to the virus, bringing the total to 14,234 confirmed fatalities and 1,789 probable deaths from COVID-19. The state’s rate of transmission was 1.08, meaning for every 100 people testing positive, the virus spreads to 108 more people. Health Commissioner Judy Persichilli noted that young people are driving new cases through large social gatherings as well as the return of some college students to campus. People aged 14-18 accounted for 4% of the new positive cases, and residents between the ages of 19-24 made up 6% of new cases. Camden County urges youth to make sure they keep their friends and family safe through a new ad campaign - "Protect Your Circle".
