6 Ways the U.S. Has Been Tracking COVID Wrong, Former CDC Chief Says
The country should be collecting these types of data in order to have a real handle on the pandemic.
In order to properly address the coronavirus pandemic, health experts need correct, comprehensive data—something the U.C. has been largely lacking. Overall, the country is experiencing significant testing and contact tracing issues, including false negatives and lengthy waiting times for test results. In addition to those issues, there are aspects of the coronavirus spread that are not being tracked, which creates a harmful knowledge gap. In an interview with Forbes, former director of the Centers for Disease Control and Prevention (CDC) Tom Frieden, MD, MPH, laid out six ways in which the U.S. has been tracking COVID wrong. Read on to learn what the former head says we aren't keeping track of but should be.

The amount of infections whose sources are unknown.
These are known as "unlinked infections" and "are rarely reported in the United States," Frieden noted in an op-ed for The Washington Post, adding that countries that have successfully curbed COVID do keep strict track of them. "Areas with unlinked infections can control the virus by improving contact tracing and physical distancing."

The rate of infection among healthcare workers.
Healthcare workers are exposed to the virus on a level that the general public is not. Tracking the number who get infected could help infectious disease experts understand the effectiveness of personal protective equipment (PPE) and the risk of different types of transmission. A July 14 report created by The Guardian and Kaiser Health News states that, in some states, "medical personnel account for as many as 20 percent of known coronavirus cases." But more accurate data would be even more valuable.
Isolating symptomatic patients.
As of now, self-quarantining is exactly that in the U.S.: it's up to individuals to do this themselves. Meanwhile, countries such as Thailand provided quarantine dorms to COVID patients, supporting their efforts. Keeping better track and making sure that – at the very least – people who show symptoms are in quarantine within three days would do a great deal to slow the spread.

How many close contacts test positive while in quarantine.
The first step after establishing who an infected person has been in contact with is to inform them that they should quarantine. Next, contact tracers and health officials should keep track of how many of those quarantined contacts go on to also test positive, as it will also provide further insight into how the disease spreads.
Local coronavirus spread.
Keeping track of how the virus moves through communities is essential. With different areas of the country on different reopening stages, possessing different population densities, and differing in other key ways, there will be variation in the speed and method of spreading. Tracking that will help not only mitigate local spread but also provide a clearer big picture look at the disease. And for more up-to-date information, sign up for our daily newsletter.
The "excess mortality" rate.
The World Health Organization (WHO) defines "excess mortality" as "mortality above what would be expected based on the non-crisis mortality rate in the population of interest." Tracking how many deaths are occurring beyond what would normally be expected in the U.S. over the duration of the pandemic is important because some people have died of COVID without having their diagnosis confirmed and because there have been and will be other deaths that are indirectly caused by the virus. (For example, people with serious conditions avoiding hospitals out of COVID fears.)
