Don't panic about new SARS-CoV-2 variant, experts say
In the leafy Johannesburg suburb of Sandringham, the National Institute for Communicable Diseases (NICD) bears a deceptive façade. Do not be fooled by its sleepy campus, clustered face brick buildings and shade cloth parking; this government facility is home to state-of-the-art biosafety laboratories and some of South Africa's top virologists, microbiologists and epidemiologists. Here, 71 scientists are tasked daily with laboratory-based disease surveillance to protect the country from pathogen outbreak events.
On March 5 2020, then health minister Zweli Mkhize announced South Africa's first Covid‑19 infection at an NICD press briefing. At the time, the NICD was an obscure acronym for many, but that quickly changed as the institution became central to the country's pandemic response.
While the Covid-19 pandemic may have waned, the NICD hasn't stopped monitoring. That is because there remains a global public health risk associated with Covid-19.
The World Health Organisation (WHO) states: 'There has been evidence of decreasing impact on human health throughout 2023 and 2024 compared with 2020-2023, driven mainly by:
high levels of population immunity, achieved through infection, vaccination or both;
similar virulence of currently circulating JN.1 sublineages of the SARS-CoV-2 virus compared with previously circulating Omicron sublineages; and
the availability of diagnostic tests and improved clinical case management.
SARS-CoV-2 circulation nevertheless continues at considerable levels in many areas, as indicated in regional trends, without any established seasonality and with unpredictable evolutionary patterns.'
Thus, while SARS-CoV-2 is still circulating, it is clearly not making remotely as many people ill or claiming nearly as many lives as it did four years ago.
Asked about this, Foster Mohale, spokesperson for the national health department, said 'there are no reports of people getting severely sick and dying due to Covid-19 in South Africa now'.
Variant under monitoring
As SARS-CoV-2 circulates, it continues to mutate.
The WHO recently designated variant NB.1.8.1 as a new variant under monitoring. There is however no reason for alarm.

SA government condemns anti-foreigner protests at healthcare facilities
Residents of Atteridgeville, grouped under Concern Tshwane Residents, are protesting outside Kalafong Provincial Tertiary Hospital, calling for undocumented foreigners to be barred from receiving healthcare services due to the alleged strain on public resources. Image: Supplied. In a strong response to a rising tide of anti-foreigner sentiment that has erupted in Gauteng and parts of KwaZulu-Natal, the Gauteng Health MEC, Nomantu Nkomo-Ralehoko, along with the National Department of Health and the South African government, has condemned alarming actions that prevent foreign nationals from accessing essential healthcare services. This week, members of Operation Dudula in Gauteng and members of the March and March movement began their campaign of manning the gates of government clinics and hospitals, including Addington Hospital, Gateway Clinic and RK Khan Hospital in Chatsworth, in a bid to prevent alleged undocumented foreigners from accessing healthcare. In an interview with IOL, the spokesperson for the Department of Health, Foster Mohale, said while the department does not condone illegal migration, the actions of the activist groups are concerning. 'We have noted with concern illegal actions around some parts of Gauteng and KwaZulu-Natal, in which individuals and organised groups prevent healthcare users, especially illegal migrants from accessing health services,' said Mohale.

Advertisement Next Stay Close ✕ Ad loading Mohale also condemned those who have come to the country illegally stating: "We also condemn people who illegally cross the border into South Africa specifically to access healthcare services. 'We urge those with concerns about this societal problem to raise them within the confines of the law instead of taking the law into their own hands because you cannot solve crime through illegal activities which may end you in jail,' he said. In a statement, the government indicated that it has noted with serious concern the reported incidents where certain groups and communities have blocked foreign nationals from accessing healthcare services at public facilities. "While the government understands the genuine frustrations of many citizens regarding the pressures on public services, including overburdened clinics and exhausted healthcare workers, members of the public are urged to raise such concerns through lawful and appropriate channels. Taking the law into one's own hands is unacceptable and undermines the values enshrined in our democratic Constitution. "Such actions stand in direct violation of the Constitution of the Republic of South Africa, which affirms the foundational values of human dignity, equality, and the advancement of human rights and freedoms. Section 27(1) of the Constitution of the Republic of South Africa, 1996, clearly provides that: 'Everyone has the right to have access to healthcare services'. This right is not subject to an individual's nationality or immigration status. Denying individuals healthcare based on their origin is a violation of our laws and values as a nation. Additionally, South Africa is a signatory to several regional and international agreements that aim to ensure access to healthcare for its citizens and, in some cases, for individuals within its borders," the government said.

GBV epidemic Study exposes system failures
JOHANNESBURG - New research in South Africa shows that COVID-19 lockdown measures worsened gender-based violence, trapping many survivors in abusive homes with limited access to help. A study in the Eastern Cape Town of Matatiele revealed that survivors faced greater barriers to police, hospitals and support services during the pandemic. Social workers also struggled to provide care, highlighting gaps in the country's emergency response systems. To discuss this further, we're joined by Dr Marinei Herselman from the University of Fort Hare's Department of Social Work and Master's Student, Bongeka Zawani.

Gaza's Nasser Hospital 'one massive trauma ward', says WHO
Israel lifted an 11-week aid blockade on Gaza on May 19. The UN human rights office said on Friday that it had recorded at least 613 killings both at aid points run by the GHF and near humanitarian convoys. "We have recorded 613 killings, both at GHF points and near humanitarian convoys - this is a figure as of June 27. Since then ... there have been further incidents," Ravina Shamdasani, spokesperson for the UN Office of the High Commissioner for Human Rights (OHCHR), told reporters in Geneva. The OHCHR said 509 of the 613 were killed near GHF distribution points. The GHF has previously said it has delivered more than 52-million meals to hungry Palestinians in five weeks "safely and without interference", while other humanitarian groups had "nearly all of their aid looted." The OHCHR said that there have been some instances of violent looting and attacks on aid truck drivers, which it described as unacceptable. BULLET WOUNDS Hundreds of patients, mainly young boys, were being treated for traumatic injuries, including bullet wounds to the head, chest and knees, according to the WHO. Peeperkorn said health workers at Nasser Hospital and testimonies from family members and friends of those wounded confirmed that the victims had been trying to access aid at sites run by the GHF. Peeperkorn recounted the cases of a 13-year-old boy shot in the head, as well as a 21-year-old with a bullet lodged in his neck which rendered him paraplegic. "There is no chance for any reversal or any proper treatment. Young lives are being destroyed forever," Peeperkorn said, urging for the fighting to stop and for more food aid to be allowed into Gaza. US President Donald Trump said on Friday it would probably be known in 24 hours whether Hamas has agreed to accept what he has called a "final proposal" for a ceasefire in Gaza. Reuters
