South African Covid Strain a new variant of the coronavirus is driving a powerful second wave of infections in South Africa. The variant has already spread to other countries in Africa and Europe and raised concerns over how it will respond to Covid-19 vaccines.
Researchers and officials reported that the prevalence of the variant was higher among young people with no underlying health conditions, and more frequently causes serious illness in such cases than other variants. The South African health department also indicated that the variant may be driving the second wave of the COVID-19 pandemic in the country, as the variant spreads faster than other earlier variants of the virus.

On 23 December UK Health Minister Matt Hancock announced that two people who had travelled from South Africa to the UK were infected with South African Covid Strain 501.V2. On 28 December, the variant had been detected in two people in Switzerland and in one in Finland. On 29 December, the strain had been detected in a visitor from South Africa to Japan, and in one overseas traveler to Queensland, Australia. On 30 December the variant was detected in Zambia. On 31 December it was also detected in France, in a passenger returning from South Africa. On 2 January 2021, the first case of this variant was detected in South Korea. Austria reported their first case of this variant, along with four cases of the UK variant on 4 January. On 8 January 2021, the Republic of Ireland reported the detection of 3 cases, all linked to travel from South Africa.
Covid-19 Vaccines Expected to Work on South Africa Coronavirus Strain
Vaccines may be less effective against the variant that has come to dominate in South Africa, but are expected to have some benefit
JOHANNESBURG—A new variant of the coronavirus that is surging across South Africa may make the existing Covid-19 vaccines less effective, but is unlikely to be totally resistant to the shots, according to leading researchers who have studied the mutations and the vaccines.
South African Covid Strain SARS-CoV-2 Variant Alarms Scientists
An additional mutation in the spike protein of the coronavirus may help it elude antibody recognition, and scientists are investigating if current vaccines will protect against it.
Scientists are testing if COVID-19 vaccines will protect against newly identified UK and South African SARS-CoV-2 variants, both of which contain an unusual number of mutations compared to other variants of the coronavirus. These mutations are concentrated mainly in the segment of the virus’s genome that codes for the spike protein, which the Pfizer/BioNTech, Moderna, and Oxford-AstraZeneca vaccines each build immunity to.

Another new coronavirus variant found in Japan
South African Covid Strain new variant of the novel coronavirus has been found in Japan, the health ministry said Sunday.
The new mutant strain, which is partly similar to different variants reported in the U.K. and South Africa, was detected in four infected people who arrived from Brazil, the ministry said.
The National Institute of Infectious Diseases (NIID) said there was no evidence at present that the new variant was highly infectious, but it was investigating whether it could cause severe symptoms and whether or not it is resistant to vaccines.

The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It was first identified in December 2019 in Wuhan, China. The World Health Organization declared the outbreak a Public Health Emergency of International Concern in January 2020 and a pandemic in March 2020. As of 1 January 2021, more than 83.5 million cases have been confirmed, with more than 1.82 million deaths attributed to COVID-19.
Symptoms of COVID-19 are highly variable, ranging from none to severe illness. The virus spreads mainly through the air when people are near each other.[b] It leaves an infected person as they breathe, cough, sneeze, or speak and enters another person via their mouth, nose, or eyes. It may also spread via contaminated surfaces. People remain infectious for up to two weeks, and can spread the virus even if they do not show symptoms.
Recommended preventive measures include social distancing, wearing face masks in public, ventilation and air-filtering, hand washing, covering one's mouth when sneezing or coughing, disinfecting surfaces, and monitoring and self-isolation for people exposed or symptomatic. Several vaccines are being developed and distributed. Current treatments focus on addressing symptoms while work is underway to develop therapeutic drugs that inhibit the virus. Authorities worldwide have responded by implementing travel restrictions, lockdowns, workplace hazard controls, and facility closures. Many places have also worked to increase testing capacity and trace contacts of the infected.
The pandemic has caused global social and economic disruption, including the largest global recession since the Great Depression. It has led to the postponement or cancellation of events, widespread supply shortages exacerbated by panic buying, agricultural disruption and food shortages, and decreased emissions of pollutants and greenhouse gases. Many educational institutions have been partially or fully closed. Misinformation has circulated through social media and mass media. There have been incidents of xenophobia and discrimination against Chinese people and against those perceived as being Chinese or as being from areas with high infection rates.
