• *Decline in SARS-CoV-2 Antibodies After Mild Infection Among Frontline Health Care Personnel in a Multistate Hospital Network — 12 States, April–August 2020
  Wesley H. Self, MD*; Mark W. Tenforde, MD, PhD*; William B. Stubblefield, MD; Leora R. Feldstein, PhD; et al. MMWR November 27, 2020 / 69(47);1762–1766
  Among 156 frontline health care personnel who had positive SARS-CoV-2 antibody test results in spring 2020, 94% experienced a decline at repeat testing approximately 60 days later, and 28% seroreverted to below the threshold of positivity.

• COVID-NET: COVID-19 hospitalizations
  The Coronavirus Disease 2019 (COVID-19)-Associated Hospitalization Surveillance Network (COVID-NET) conducts population-based surveillance for laboratory-confirmed COVID-19-associated hospitalizations in children (persons younger than 18 years) and adults. The current network covers nearly 100 counties in the 10 Emerging Infections Program (EIP) states (CA, CO, CT, GA, MD, MN, NM, NY, OR, and TN) and four additional states through the Influenza Hospitalization Surveillance Project (IA, MI, OH, and UT). The network represents approximately 10% of US population (~32 million people).
  Cases are identified by reviewing hospital, laboratory, and admission databases and infection control logs for patients hospitalized with a documented positive SARS-CoV-2 test.
  Data gathered are used to estimate age-specific hospitalization rates on a weekly basis and describe characteristics of persons hospitalized with COVID-19. Laboratory confirmation is dependent on clinician-ordered SARS-CoV-2 testing. Therefore, the rates provided are likely to be underestimated as COVID-19-associated hospitalizations can be missed due to test availability and provider or facility testing practices.
  COVID-NET hospitalization data are preliminary and subject to change as more data become available.

• Death Count Expected To Soar As NYC Says It Will Begin Reporting Probable COVID Deaths In Addition To Confirmed Ones
  Gwynne Hogan, WNYC, April 8, 2020
  New York City officials will begin to count suspected COVID-19 deaths of people who die at home following a WNYC/Gothamist report revealing a staggering number of such deaths that were not included in the official tally.

• Protocol for a national probability survey using home specimen collection methods to assess prevalence and incidence of SARS-CoV-2 infection and antibody response
  Aaron J.Siegler, Patrick S.Sullivan, TravisSanchez, BenLopman, et al. Annals of Epidemiology. In press, pre-proof 11 August 2020
  We will conduct a national serosurvey for SARS-CoV-2 positivity and immune response. A probability sample of US addresses will be mailed invitations and kits for the self-collection of anterior nares swab and finger prick dried blood spot specimens. Within each sampled household, one adult 18 years or older will be randomly selected and asked to complete a questionnaire and to collect and return biological specimens to a central laboratory. Nasal swab specimens will be tested for SARS-CoV-2 RNA by RNA PCR; dried blood spot specimens will be tested for antibodies to SARS-CoV-2 (i.e., immune experience) by enzyme-linked immunoassays. Positive screening tests for antibodies will be confirmed by a second antibody test with different antigenic basis to improve predictive value of positive (PPV) antibody test results. All persons returning specimens in the baseline phase will be enrolled into a follow-up cohort and mailed additional specimen collection kits 3 months after baseline. A subset of 10% of selected households will be invited to participate in full household testing, with tests offered for all household members aged ≥3 years. The main study outcomes will be period prevalence of infection with SARS-CoV-2 and immune experience and incidence of SARS-CoV-2 infection and antibody responses.

• Symptom tracker - We Count COVID-19
  Amy Kalkenbrenner's confidential symptom tracker to better understand COVID-19. This online survey should be filled out at the time of sickness, whether or not the person has been tested for coronavirus. This survey is open to all people in the US who are 18 years or older, and parents may report for their children younger than 18.
• The COVID Tracking Project
  The COVID Tracking Project collects information from 50 US states, the District of Columbia, and 5 other U.S. territories to provide the most comprehensive testing data we can collect for the novel coronavirus, SARS-CoV-2. We attempt to include positive and negative results, pending tests, and total people tested for each state or district currently reporting that data.
• Tracking The Pandemic: How Quickly Is The Coronavirus Spreading State By State?
  Elena Renken and Daniel Wood, NPR Shots, April 21, 2020
  On April 12, the U.S. became the nation with the most deaths globally, but there are early signs that the U.S. case and death counts may be leveling off, as the growth of new cases and deaths plateaus. The pattern isn't consistent across the country, as new hot spots emerge and others subside. To see how quickly your state's case count is growing, click ....

• ‘How Could the CDC Make That Mistake?’
  Alexis C. Madrigal, Robinson Meyer. The Atlantic. May 21, 2020
  The government’s disease-fighting agency is conflating viral and antibody tests, compromising a few crucial metrics that governors depend on to reopen their economies. Pennsylvania, Georgia, Texas, and other states are doing the same.
