Puzzled scientists seek reasons behind Africa's low fatality rates from pandemic

Africa’s overburdened public health systems, dearth of testing facilities and overcrowded slums had experts predicting a disaster when Covid-19 hit the continent in February. The new coronavirus was already wreaking havoc in wealthy Asian and European nations, and a United Nations agency said in April that, even with social-distancing measures, the virus could kill 300,000 Africans this year. In May, World Health Organization (WHO) warned that 190,000 people on the continent could die if containment measures failed. Yet as the world marks 1 million Covid-19 deaths, Africa is doing much better than expected, with a lower percentage of deaths than…

You can view the image within the messaging app, you can see what you’re getting, surely there’s no harm in saving it to your…

Most Covid-19 Infections spread by air, not surfaces

Maybe you come home and leave your shoes outside. You disinfect your packages, wipe down your groceries, throw your clothes in the wash, and disinfect every surface you have touched, like the door handle, countertops and cabinets. Finally, you wash or sanitize your hands. Welcome to life in the global pandemic, thanks to SARS-CoV-2, the virus responsible for Covid-19.

Coronavirus: WHO sets rules for testing African herbal remedies

World Health Organization (WHO) has agreed rules for the testing of African herbal remedies to fight Covid-19.

Madagascar's leader has been promoting an untested product he says can cure the disease despite the WHO warning against using untested remedies. WHO said the new rules were aimed at helping and empowering scientists in Africa to conduct proper clinical trials. The move comes as the number of confirmed cases of coronavirus…

Some good news on Covid-19

The best hope for ending the covid-19 pandemic is a vaccine. There is no shortage of candidates. The World Health Organisation is tracking 34 in various stages of development. How well they will work, though, is another matter. On September 9th AstraZeneca, a drug firm, announced it was pausing its trials after a participant fell ill. Such pauses are common in vaccine development, a discipline in which effort does not always bring reward. Despite much research, only an imperfect vaccine is available for dengue fever (it has limited efficacy and can cause nasty side-effects). In 1987 the first trial of…

Ssshhh!! Keep your voice down to slow Covid-19 spread

“Say it, don’t spray it.” The old adage is now being hailed by experts as a way to slow the spread of coronavirus. Research analyzed by The Atlantic suggests talking more quietly — or not at all — can drastically reduce the rate of Covid-19 transmission. The virus primarily spreads through particles that exit our nose and mouth when we sneeze, cough, sing and — you guessed it — speak. These particles fall onto nearby surfaces or linger in the air, waiting to be inhaled by passersby. Wearing a mask acts as a barrier between these potentially virus-laden particles and…

WhatsApp: There are some ‘crash code’ circulating on the popular messaging app. This is how to avoid crashing your app

A new series of text bombs or 'crash codes' have been discovered that cause WhatsApp to continually crash on both iPhone and Android handsets.

Biggest mistake people make when getting rid of old computers and phones

During this pandemic with time at home, many people are cleaning and organizing their closets, garage, or attic. It makes sense. Afterward, you have a sense of accomplishment and a pile of things you can sell or donate. Since 1995, Craigslist has been the internet’s classifieds site, but now you have other options. If you’re on Facebook, there’s the Marketplace. You’d be remiss in not checking the Swip Swaps on the site. There is one critical step many people forget to take before getting rid of their old devices: Proof is in the discarded One security researcher decided to find…
