A new app, called ResApp, detects COVID-19 infection by just the sound of a cough. The app uses machine learning to analyze cough sounds.

‘The results revealed that the app was able to correctly detect Covid-19 in 92 per cent of people with the infection, compared to lateral flow tests that can detect around 72 per cent of symptomatic cases and 58 per cent of asymptomatic ones.’
ResApp was developed by professor Udantha Abeyratne at the University of Queensland. US drug major Pfizer has recently offered $100 million to acquire the Brisbane-based company. "The sheer scale of this global pandemic and the likely evolution to an endemic disease means we need more scalable diagnostic tools that can balance our current over-reliance on rapid antigen and PCR tests," Professor Catherine Bennett, a member of ResApp's Covid-19 Scientific Advisory Board, was quoted as saying.
"By rapidly ruling out Covid-19, ResApp's Covid-19 test would significantly reduce the number of rapid antigen and PCR tests required, while still maintaining the disease surveillance needed to manage the continued impact of Covid-19," she added.
Mucormycosis (Black Fungal Disease): A Complication of COVID-19
Mucormycosis is spread by spores from the black fungus, Mycormycetes. It mainly affects people with a weak immune system and attacks the lungs and other organs of the body. It is also known as Black Fungal Disease.

The participants completed surveys on any symptoms they were experiencing, and coughed into a smartphone with the app installed.

Test your Knowledge on Coronavirus (COVID-19)
Coronavirus is a large positive-strand RNA virus that is surrounded by a protein envelope. The virus obtains its name from the S protein spikes on its surface, which resemble a crown. The overall pattern of increasing coronavirus cases is shown to spike up with the “second wave” of COVID-19.
With spiking effects of the second wave of coronavirus, the best way to keep it at bay is to follow COVID-appropriate safety practices like wearing a mask, regularly cleaning your hands, and coughing into a bent elbow or tissue along with physical distancing (6 feet about 2 arm's length), that may help evade the severity of COVID-19 infection.

Is �COVID Teeth� a Possible Symptom of the Fourth Wave of COVID-19?
Are new COVID-19 variants showing teeth and gum problems as early signs of COVID-19 infection? Experts warn not to ignore oral health.

According to the company, the app will initially be used in settings like travel, sports, entertainment, and healthcare, where frequent Covid-19 testing is required.
"We are very excited about these preliminary results for detecting Covid-19 using cough audio recorded on a smartphone," Tony Keating, CEO and Managing Director of ResApp was quoted as saying.
"These algorithms offer a unique opportunity to provide a rule out screening test for Covid-19 at scale across the world, reducing the distribution challenge, the cost and the environmental impact of rapid antigen and PCR testing," he added.
Keating said the company aims to accelerate commercialization by immediately engaging with regulators globally.
