This theory has been undercut by international research, and U.S. biostatistics researchers have now added domestic confirmation.
The American Medical Association’s
JAMA Network Open published their research earlier this month, finding that the riskiest environment for viral transmission – the home – is not particularly risky when the infected person is not symptomatic.
The five researchers sought to identify the “household secondary attack rate” for SARS-CoV-2, the virus that causes COVID-19. Secondary attack rate refers to the number of new cases among contacts divided by the total number of contacts.
Four of the five are in the University of Florida’s Department of Biostatistics, while the fifth is in the University of Washington’s Department of Biostatistics and the Fred Hutchinson Cancer Research Center in Seattle.
A silicone ball implanted in the stomach could help relieve persistent heartburn. The device, about the size of a ping pong ball, is stitched to the top of the inside of the stomach via keyhole surgery.
In position, the ball presses down on the one-way valve that lets food move from the oesophagus the food pipe and into the stomach.
This stops the valve opening the wrong way and letting acid leak from the stomach back up into the oesophagus, which is common in heartburn patients and causes the ‘burning’ pain.

The Phase 3 trial of another investigational coronavirus disease 2019 (COVID-19) vaccine has begun enrolling adult volunteers. The randomized, placebo-controlled trial will enroll approximately 30,000 people at approximately 115 sites in the United States and Mexico. It will evaluate the safety and efficacy of NVX-CoV2373, a vaccine candidate developed by Novavax, Inc., of Gaithersburg, Maryland. Novavax is leading the trial as the regulatory sponsor.

-19) is a randomized, placebo-controlled, observer-blinded study to evaluate the efficacy, safety and immunogenicity of NVX-CoV2373 with Matrix-M in up to 30,000 subjects 18 years of age and older compared with placebo. The trial design has been harmonized to align with other Phase 3 trials conducted under the auspices of Operation Warp Speed, including the use of a single external independent Data and Safety Monitoring Board to evaluate safety and conduct an unblinded review when predetermined interim analysis events are reached.
The trial’s primary endpoint is the prevention of PCR-confirmed, symptomatic COVID-19. The key secondary endpoint is the prevention of PCR-confirmed, symptomatic moderate or severe COVID-19. Both endpoints will be assessed at least seven days after the second study vaccination in volunteers who have not been previously infected with SARS-CoV-2.
