See which states meet or exceed test positivity rates recommended by the World Health Organization. The COVID crisis has created an unprecedented need for contact tracing across the country, requiring thousands of people to learn key skills quickly. The job qualifications for contact tracing positions differ throughout the country and the world, with some new positions open to individuals with a high school diploma or equivalent. Six months after the arrival of the first COVIDwarning smartphone apps built on a privacy-preserving framework from Apple and Google, they remain yet another coronavirus pandemic scarcity.
This tool can be used to estimate the impact of a contact tracing program on transmission and strategize how to increase it.
President Biden announced a plan with much fanfare for free at-home COVID tests as part of his effort to tame the pandemic this winter. Scientists have little data yet on whether omicron causes more severe disease than other variants. Cost and irregular availability of rapid COVID tests means that Americans often must make choices about when to use them. We asked three experts from different disciplines to respond to a selection of questions from readers about how to think about risk and navigate another COVID winter.
Cheap, at-home coronavirus tests have been in short supply, and although their availability is slowly ticking up, a crush of demand around Thanksgiving will almost certainly make the search difficult again. Global Confirmed Loading Global Deaths Loading Confirmed Loading Deaths Loading Global Map U. For example, when comparing colleges based on graduation rates, you examine the percentage of students that graduate out of all the enrolled students at each institution.
The percentage of all graduating students in relation to the number of STEM majors is much less informative to the decision-making process. This occurs only in cases where a person has been tested repeatedly within the time period of deduplication utilized by a state. Fortunately, repeated testing within a short time span is uncommon.
As stewards of good data, we reached out to each state health department that would experience a change in positivity on the CRC site due to these updates. Encouragingly, some states were eager to discuss how we calculated positivity, sharing new data to improve the calculations and prompting internal discussions on how to address positivity moving forward. Unfortunately, even though we now provide five distinct methods of calculating positivity, six states and territories still do not provide sufficient data for any of our calculation methods shown below.
Pandemic pressures have yet to motivate transformational improvements in the way we collect, organize, and report data across the United States. Our work over the past 22 months has revealed pervasive problems with positivity calculations that local, state, and federal authorities need to address. They are: Lack of a Universal Dataset The CDC maintains the central repository of national public health data, but its collection is incomplete because states are not required to submit their data. In addition, the CDC does not impose one standard method for calculating positivity.
Absent a universal dataset, we have no way of comparing states. Despite our revamping of positivity on the Coronavirus Resource Center, there is not a single calculation method for which all states provide the appropriate data.
The lack of complete federal data can also lead to confusion among citizens, localities, states, and the federal government. Does a person have to have symptoms? Do they need to get tested once they are already hospitalized? In order to determine and report a confirmed positive person, we need to know what a positive person really is. That, too, varies from state to state and has changed throughout the pandemic. This issue has been repeated with breakthrough cases, reinfections, and asymptomatic cases.
But the deduplication window is defined differently across states. We need a standard data dictionary from which all states can work. Poor Data Granularity Case-level granularity with accurate timestamps and locations is ideal for positivity measurement.
The goal of calculating positivity is to understand when, where, and if there is an outbreak so that authorities can address it, people can modify their behavior, and resources can be allocated. Additionally, some counties may be experiencing an outbreak while the rest of the state is not.
Without geographic granularity, COVID hotspots can be washed out by the low positivity of the rest of the state. These nuances affect many lives, but can only be detected with complete, granular testing data. We are hopeful that our new positivity calculation hierarchy will bring some of these issues into the public dialogue and enable more detailed, robust analysis of COVID trends. We are encouraged by states that have attempted to improve their data reporting in response to this change at the CRC and hope more will follow.
Our goal is to continue providing the best data and informative analysis to help individuals and policymakers make ever-important decisions about health and safety as the pandemic continues.
Abu-Raddad and R. Accessed 11 August Accessed 08 December Explore Vaccination Progress by U. Explore Vaccination Progress by Country. New Explore how U. By Chris Beyrer. By Larry Corey. For example, some of those doses are going to be targeted to India, which is facing a tragic surge in cases.
The idea is to get vaccines to where they are needed most. But it has to be done early. And then the third strategy is based on foreign policy decisions. This is my least favorite. For example, the Biden Administration has donated doses to Canada and Mexico, obviously because they are countries on our borders where we have a self-interest in preventing virus importations. Is there enough time to deliver the vaccines to make a difference?
Well, with India, I must say, it's late. Then you need to give them two doses. You can look at where outbreaks are really emerging like in Nepal or Thailand to target vaccine doses. What more can the United States do to address the global situation? The United States needs to do a lot more than donating vaccines. The United States needs to support the expansion of vaccine manufacturing both domestically and abroad.
It needs to help build that capacity, provide training for personnel, and relax export restrictions on supplies, reagents, and chemicals that go into manufacturing vaccines. This needs to be a global partnership among the wealthy nations to coordinate all of the responses needed.
