The rapid increase in the number of infections is the most obvious reason why new variants of the virus have been emerging recently. Case numbers doubled in just two months at the end of 2020.

Even those that live in areas where the population has already been vaccinated would not be totally protected if the virus mutates elsewhere.
Ghana’s mid-year target of procuring and administering 17.6 million COVID-19 vaccine doses may be constrained by global supply, cold chain capacity, and vaccine hesitancy.
In the context of COVID-19, we’re hearing about new mutations, strains and variants all the time. It’s no wonder it can all get a bit confusing.
Never has the saying ‘dynamite comes in small packages’ been more apt.
These variants are definitely cause for concern. But there’s every indication we can adapt our vaccine strategy to combat these and other variants going forward.
Masks between 7am and 9am for those born before 2005 – Sweden’s coronavirus policies are unnecessarily confusing.
A bat virus discovered a decade ago in Cambodia indicates that pangolin trafficking remains a credible explanation for the origin of the Covid-19 pandemic.
Everything you need to know about fit, filtration and breathability.
The virus is evolving and new strains are more transmissible. Will the vaccines work against these new variants? How can researchers stay ahead of the virus’s evolution?
Recently announced travel restrictions are intended to curb the spread of COVID-19 variants. However, we need to do a better job of tracking arrivals into the country.
Getting pharmacies more involved could be a game changer, particularly for reaching minorities, older adults without internet access and others left behind.
Ever since the 2001 SARS outbreak and H5N1 avian flu in 2003, we’ve developed tools to monitor diseases that transmitted from animals to humans. But what does a large-scale roll-out entail?
With slow vaccine distribution and manufacturing, some people won’t get the second dose on time. But does it matter?
Jackson Mthembu’s death drives home the seriousness of the COVID-19 pandemic in the country.
The microbes in your gut influence how your immune system reacts to bacteria and viruses. A severe immune reaction is deadly; a small one lets the virus win. The right balance may depend on your diet.
Scientists have observed that 501Y.V2 has quickly become “dominant” among multiple variants that have been circulating in the South African population.
Multiple COVID-19 variants are circulating around the world and becoming more common. These mutations can alter the ability of the virus to take hold and replicate within our cells.
We’ve gone from a novel virus to several COVID-19 vaccines in less than a year. Here’s what we’ve learned from earlier vaccines to allow this to happen.
COVID-19 has been found in pets, zoo animals and in a wild mink in Utah. Monitoring wildlife for COVID-19 is important for animals and humans, both of whom face risks from a jumping virus.
