Tale of Covid-19 in two Indian cities: Dharavi, Mumbai, a rare success, and Delhi which was “messed up”

‘Asia's largest slum Dharavi was being seen as a 'Covid-engine' that will drive Mumbai in the wrong direction. But with conscious efforts, the slum's Covid doubling rate has come down to 44 days, twice as good as Mumbai’s 22. Delhi sadly is a study in contrast with India’s highest test positivity rates. In episode 496 of ThePrint's #CutTheClutter, Shekhar Gupta talks about the lessons from Dharavi & new plan for Delhi.’

The next Apple Watch could be a powerful COVID-19 early warning system

‘The Apple Watch already has a number of sensors that could effectively detect early signs of COVID-19, and the most important one—a pulse oximeter—may be on the way.

‘Toward the end of his life, one of Steve Jobs’s hopes for Apple was that it could play a role in helping people stay healthy. After he died, that ambition was most clearly expressed in the Apple Watch. The company has always pushed to make its wearable something more than a fitness tracker—a more powerful, clinically relevant device.’

Covid-19, ‘silent hypoxia’ and a simple way to identify patients sooner (even do it at home with a ‘pulse oximeter’)

‘We are just beginning to recognise that Covid pneumonia initially causes a form of oxygen deprivation we call “silent hypoxia” — “silent” because of its insidious, hard-to-detect nature...

‘There is a way we could identify more patients who have Covid pneumonia sooner and treat them more effectively — and it would not require waiting for a coronavirus test at a hospital or doctor’s office. It requires detecting silent hypoxia early through a common medical device that can be purchased without a prescription at most pharmacies: a pulse oximeter...

‘Pulse oximetry is no more complicated than using a thermometer. These small devices turn on with one button and are placed on a fingertip. In a few seconds, two numbers are displayed: oxygen saturation and pulse rate. Pulse oximeters are extremely reliable in detecting oxygenation problems and elevated heart rates.’
