FreshAirClip – Wearable detects personal exposure to SARS-CoV-2

What is this new device?

“The Fresh Air Clip is a wearable device that can be used to assess exposure to SARS-CoV-2 in the air,” said the clip’s creator Krystal Godri Pollitt, Ph.D. an assistant professor of epidemiology (Environmental Health Sciences) at the Yale School of Public Health and also an assistant professor of chemical and environmental engineering at Yale.

Briefly, how does it work?

Exhaled respiratory droplets and aerosols can carry infectious viruses and are an important mode of transmission for COVID-19. Recent studies have been successful in detecting airborne SARS-CoV-2 RNA in indoor settings using active sampling methods. Integration of passive samplers into wearable designs can be used to better understand personal exposure to the respiratory virus.

“With this clip we can detect low levels of virus that are well below the estimated SARS-CoV-2 infectious dose,” Godri Pollitt said. “The Fresh Air clip serves to identify exposure events early, alerting people to get tested or quarantine. The clip is intended to help prevent viral spread, which can occur when people do not have this kind of early detection of exposure.”

FDA authorizes 2 new at-home test for Covid-19

Who are the two new at-home covid test from?

Roche and Siemens At-Home Tests, Which Went Through New Biden Administration Accelerated Review Program

What are the at-home test called?

Roche at-home test  is called :SARS-CoV-2 Rapid Antigen Test 
Siemens at-home test is called: CLINITEST® Rapid COVID-19 Self-Test

Why make a big deal about these two?

These two tests were authorized in just two months since joint FDA-NIH Program Accelerating Test Developers through regulatory process was announced. That should mean, more tests from different manufactureres should be approved faster and more tests can be manufactured and delivered to the people that need it most.

In late October, HHS announced the Administration would invest $70 million from the American Rescue Plan to help bring more high-quality, at-home tests onto the market in the U.S. in coordination with FDA. This new Independent Test Assessment Program (ITAP) is helping identify manufacturers of high-quality tests and encouraging them to bring those tests to the U.S. market, increasing options for people and overall supply and potentially lowering costs.


500 Million Free ‘at home test’ kits to be issued by the US government.

What’s happening now?

President Biden in his speech today said about 500 million at-home test kits will be issed by the federal goverment for free.

When can I get the free at-home test kits?

How can I get them?

A federal website will be created where you fill in a form and the test(s) will be shipped to your home. *Update(1/13/2022)* the website will be: and when they bring it out live.

Do I have to report the results to the government?

No, according to officials “Those who utilize them will not have to report their results to public health agencies” source



Researcher hack at-home test to spoof results.

Researcher, Ken Gannon of F-secure found a flaw in how software reported results on the testing unit and was able to intercept and change the results before the data was submitted to the accompanied app via bluetooth. The test was Ellume’s at-home covid test.

The researcher reported the data spoof method to Ellume and Ellume to their credit quickly fixed the issue. Read more here.


New RNA-based breath test to detect COVID-19

What is the new Covid-19 breath test?


Scientists at Brown University have developed an RNA-based breath test to detect COVID-19. A breathalyzer that reverse-transcribes RNA from airborne SARS-CoV-2 in breath, predicts lower respiratory tract involvement and is less invasive than alternative testing approaches, report researchers in The Journal of Molecular Diagnostics.


Opinion: Covid at home test – How to win

At home covid testing has to catch up, catch up really fast if we are to reduce the spread of the next possibly worse mutation. We are not talking about getting rid of Covid at this time, just making sure we survive this pandemic. The question becomes how to make at home testing a mandatory thought in people’s minds on a daily basis? Like brushing teeth as an example of a daily activity that we follow.


On the horizon:Researchers develop a molecule that blocks SARS-CoV-2 infection

A research team at Aarhus University in Denmark has developed a new molecule that attaches to the surface of SARS-CoV-2 virus particles. This attachment prevents the virus from entering human cells and spreading the infection.

An aptamer is a piece of DNA or RNA that folds into a 3D structure that can recognize a specific target molecule of interest. By attaching itself to the virus surface, the RNA aptamer prevents the Spike protein from serving as a key that allows the virus to enter a cell.


At home covid-19 test for Free!

Who gets at home covid-19 test for free?

President Biden is set to announce today that private health insurance plans will soon reimburse people who buy over-the-counter at-home rapid tests for COVID-19.

What about the rest of the people?

Those who are uninsured or who have public health insurance, such as Medicare or Medicaid, will not be eligible to be reimbursed for at-home test purchases, although the administration will distribute 50 million free at-home tests at health clinics and other community sites.

When does this start?

They are being rolled out as of today.
**Update**  (1/10/21)
Starting Saturday,(1/15/21) private health insurers will be required to cover up to eight home COVID-19 tests per month for people on their plans. The Biden administration announced the change Today (1/10/21)

Americans will be able to either purchase home testing kits for free under their insurance or submit receipts for the tests for reimbursement, up to the monthly per-person limit. A family of four, for instance, could be reimbursed for up to 32 tests per month. PCR tests and rapid tests ordered or administered by a health provider will continue to be fully covered by insurance with no limit.


Maryland to distribute 500K At-Home COVID-19 Test Kits.

What is happening?

Governor Larry Hogan announced that state of Maryland will distribute 500,000 at home test kits for Covid-19 thoughout the state free of charge.

What kind of at home test will they distribute?

State of Maryland will distribute Abbot’s BinaxNow AG At-home Covid 19 rapid test.
