Outside Europe and the Americas, few places release data about excess deaths. No such information exists for large swathes of Africa and Asia, where some countries only issue death certificates for a small fraction of people. For these places without national mortality data, The Economist has produced estimates of excess deaths using statistical models trained on the data in this tracker . In India, for example, our estimates suggest that perhaps 2.3m people had died from covid-19 by the start of May 2021, compared with about 200,000 official deaths. While covid-19 was devastating New York in March 2020, cities in western Europe were also suffering severe outbreaks.
We collect data on a range of policies, including school closures, stay at home orders, economic support for households, and vaccination policy. The first case of COVID-19 was reported Dec. 1, 2019, and the cause was a then-new coronavirus later named SARS-CoV-2. SARS-CoV-2 may have originated in an animal and changed so it could cause illness in humans.
Tests that identify host immune response are referred to as serological tests and are intended to be administered as simple blood tests. These tests can indicate whether an individual has been previously exposed to COVID-19. Antibody test results are important in detecting infections in individuals with few or no symptoms and have been used in conjunction with RT-PCR results in establishing a diagnosis or exclusion of COVID-19 infection. IgM and IgG are the two major antibodies assessed by serologic testing.

The Pfizer, Moderna and J&J vaccines, currently the only vaccines to receive an Emergency Use Authorization to be distributed in the United States. Pfizer and Moderna are molecular RNA based and both vaccines have around a 95% efficacy rate; Pfizer drops to about 64% against the Delta variant. The J&J vaccine has shown to have an efficacy of around 66% in preventing moderate to severe COVID-19 disease and 86% efficacy at reducing severe illness and hospitalizations. Moderna and J&J have not concluded their analysis on the efficacy of their vaccines against the Delta variant.
Are recovered persons with persistent positive test of COVID-19 infectious to others?
Persons who have tested persistently or recurrently positive for SARS-CoV-2 RNA have, in some cases, had their signs and symptoms of COVID-19 improve. When viral isolation in tissue culture has been attempted in such persons in South Korea and the United States, live virus has not been isolated. There is no evidence to date that clinically recovered persons with persistent or recurrent detection of viral RNA have transmitted SARS-CoV-2 to others.
Despite these observations, it’s not possible to conclude that all persons with persistent or recurrent detection of SARS-CoV-2 RNA are no longer infectious. There is no firm evidence that the antibodies that develop in response to SARS-CoV-2 infection are protective. If these antibodies are protective, it’s not known what antibody levels are needed to protect against reinfection.
A new variant may yet trigger another chapter in the COVID-19 pandemic and societies must be prepared to respond if and when that happens. “Use and care of masks,” Centers for Disease Control, February 25, 2022, cdc.gov. “Mortality risk of COVID-19,” Our World in Data, ourworldindata.org. Even though inequalities in global vaccine access have meant that few there have received three doses, and most have not yet received a single dose.

Further, higher-than-expected efficacy may help offset coverage challenges that surveys have suggested. Those two factors could advance the timeline, and make Q3 a little more likely than Q4. A secondary effect of the recent vaccine trials is to make Q more likely for herd immunity than Q4. While the potential for a transition toward normalcy in just a few months is encouraging, many signs suggest that the next six to eight weeks will be difficult. Case and death numbers are at or near all-time highs in many locations, new variants may accelerate short-term transmission, and vaccine rollout has not yet proceeded far enough to protect much of the population. Strong public-health measures will remain critical to saving lives during this period.
Within hours of drop-off at the lab, Alexandria Boehm, a professor of civil and environmental engineering at Stanford, receives the results online. Boehm, known to colleagues as Ali, reviews the data and uses it to create reports about the prevalence of COVID-19 on campus. In April, Stanford’s COVID Dashboards expanded to include these measurements and trends.
ASU also is working with the Arizona Department of Health Services to analyze and produce data from the zip codes in which our campuses are located to better understand virus trends at the local level. ASU is following all CDC guidelinesrelated to higher education. ASU provides weekly updates on our COVID-19 Management Strategy, which supports virus management efforts at the state, local and university levels. If you are a Washington University employee or student whose physical presence is required on campus to perform essential services, you are required to self-screen daily for COVID-19 symptoms beforecoming to campus.
The COVID-19 vaccine is recommended for anyone trying to become pregnant now or who wants to get pregnant in the future. There is currently no evidence that COVID-19 vaccination causes any problems with pregnancy, and there is no evidence that fertility problems are a side effect of the COVID-19 vaccine. Consult with your OB/GYN physician for further information and guidance prior to getting the vaccine. Reports of Guillain-Barré Syndrome in people who have received the J&J/Janssen COVID-19 vaccine.
During this challenging time, many people are looking to help the community and hospital. Mass General Brigham has launched a system-wide effort to ensure that patients, providers and employees are treated equitably and have access to necessary information during the COVID-19 pandemic. If you need language interpretation or online help, contact the call center and say your preferred language when connected.
We encourage those who need a vaccination certificate to continue to talk to your local city hall or Ward Office for clarification. When traveling internationally, people who received their vaccine in the United States should travel with their white CDC vaccination card. Those who received their vaccine in Japan and wish to apply for a vaccine certificate should contact their Ward Office for additional information. The American Heart Association is working to ensure optimal care for patients with cardiovascular disease who contract coronavirus (COVID-19). Get the latest guidance for CPR and resuscitation during the COVID-19 pandemic, as well as podcasts, updates, training and resources. The city has led the nation in vaccination rates, but booster rates have stalled.
Courses are offered in-person, on-campus at a reduced capacity and are also available to students digitally through ASU Sync and iCourses. Students can choose their preferred learning environment to accommodate their needs. To expand testing availability and access for the ASU community, the university is now offering individual drop-off COVID-19 saliva testing to all students, faculty and staff. Three students are in isolation on the ASU Tempe campus, where 2,544 students live; three students are currently in isolation on the ASU Downtown Phoenix, ASU West or Polytechnic campuses. A total of 687 students live in university housing on the ASU Downtown Phoenix campus; 198 students live on the ASU West campus; and 162 students live on the ASU Polytechnic campus.
Kim has called the outbreak a “great upheaval,” berated officials for letting the virus spread and restricted the movement of people and supplies between cities and regions. North Korea’s anti-virus headquarters reported a single additional death, raising its toll to 63, which experts have said is abnormally small compared to the suspected number of coronavirus infections. We meet regularly and discuss our newest data, plans for testing new variants and pathogens, and how to use the data for pandemic response. We also work closely with Russell Furr’s group at Environmental Health & Safety and communicate with them weekly. At Stanford, the Provost’s office provided seed funding in late 2020 for a pilot project using wastewater to gain insights about COVID-19 on campus. That project involved School of Medicine collaborators Ami Bhatt, Ben Pinsky, and Bonnie Maldonado, as well as Julia Nussbaum of the Stanford Water Planning & Stewardship team.
