In what feels eerily like a return to 2020, southern China is facing an outbreak that's reviving memories of the pandemic, but this time, it's not Covid-19.
It's chikungunya, a virus spread by mosquito bites that causes sudden fever and severe joint pain, often lingering for months or even years.
According to Bloomberg, the outbreak's epicentre is Foshan, a city in Guangdong province in South China, where over 6500 cases have been reported in just a few weeks.
The local government is acting swiftly: hospitals are keeping patients under mosquito nets, drug purchases are being monitored, and communities are undergoing mass testing and disinfection campaigns.
What is chikungunya
Pronounced chik-un-GUN-yuh, the virus was first identified in Tanzania in 1952, but only arrived in China in 2008. Today, it's known to circulate in over 110 countries, mostly in Africa, South and Southeast Asia, and now, more prominently, southern China.
According to the World Health Organisation (WHO), symptoms usually appear 3–7 days after a mosquito bite and include: Sudden high fever.
Intense joint and muscle pain.
Skin rashes.
Headaches.
Swelling of the joints.
While most people recover within a week, some may suffer from chronic joint pain for months, sometimes even years. Fortunately, deaths are rare, and the virus is not spread person-to-person, only through mosquito bites.
Still, in vulnerable groups like newborns, the elderly, and those with chronic illnesses like diabetes or heart disease, the illness can hit harder.

With over 7,000 cases reported, authorities are implementing measures reminiscent of the pandemic.

Not another lockdown, but a wake-up call.
Though the virus itself isn't new, the scale of the response in China is catching attention worldwide. Authorities are now tracking people buying over-the-counter fever or pain relief medication, a tactic used during the Zero-Covid strategy, reports "Bloomberg".
Rather than lockdowns or digital tracking, outbreak control should focus on vector management and reducing human mosquito contact, Dr Donal Bisanzio, a senior epidemiologist at RTI International, a nonprofit research group, told BBC News.
According to Kang Min, Director of Guangdong CDC's Institute of Infectious Disease Prevention and Control, new cases are slowing down, but challenges remain due to international travel and the flood season, which fuels mosquito breeding.
Here's what local authorities are doing: Mass disinfection drives and stagnant water removal.
Encouraging window screens and mosquito nets.
Fines of up to 1,000 yuan (R2 600) for businesses not cleaning up mosquito habitats.
Seven-day health campaigns in high-risk towns like Lecong.
Communities light mosquito coils at the same time daily to maximise the repellent effect.
What does this mean for travellers and locals alike?
With the outbreak spreading to 12 cities in Guangdong province and a first imported case in Hong Kong, a 12-year-old boy who had visited Foshan, global attention is growing. The US State Department has even advised travellers to China to exercise increased caution.
In an interview with eNCA, Professor Tulio de Oliveira from the Centre for Epidemic Response and Innovation at Stellenbosch University discussed the chikungunya virus.
He noted that in South Africa, the NICD has recorded ten travel-related cases of this virus from December to July.
During the winter months, there are no immediate concerns about widespread outbreaks in South Africa. However, emphasised that the real concern for South Africa will arise in the summer when mosquito populations increase.
"The variant causing concern originated in Réunion Island in March, leading to a significant outbreak with nearly 50 000 infections. While it also spread to Mauritius, effective measures helped control it there."
He added, 'This variant has mutations that allow it to spread more easily through certain mosquito species.'
'Climate change and rising temperatures are expanding the areas where mosquitoes thrive, which could lead to more chikungunya cases. '
He urged vigilance as the situation evolves, especially with the potential for more introductions of the virus into South Africa as the seasons change.
How to protect yourself Use mosquito repellent daily, especially in humid, rainy seasons.
Install mosquito screens on windows and doors.
Sleep under mosquito nets, especially if you live near standing water.
Wear long sleeves and pants if you're outside at dawn or dusk.
Eliminate stagnant water in plant pots, buckets, or outdoor containers.
If you've travelled to affected areas and develop fever, joint pain, or rash, see a doctor and mention your travel history. Early detection helps avoid complications and stops the spread.

WHO says 99 dead from malnutrition in Gaza this year
GENEVA - The World Health Organization said Thursday that 99 people were now known to have died from malnutrition in the Gaza Strip so far this year, with the figure likely an underestimate. International outrage over the humanitarian situation in Gaza has ratcheted up pressure on Israel, with UN agencies warning of famine in the devastated Palestinian territory. WHO chief Tedros Adhanom Ghebreyesus called for scaled-up, sustained and unimpeded aid to be allowed to flow into Gaza, via all possible routes. Gazans "have limited access to basic services, have faced repeated displacement and are now suffering from a blockade of food supplies", Tedros told the UN correspondents' association ACANU. "Malnutrition is widespread and hunger-related deaths are rising," he said. "In July, nearly 12,000 children under five years were identified as suffering from acute malnutrition -- the highest monthly figure ever recorded. "So far this year, 99 people have died from malnutrition, including 29 children under five. These reported numbers are likely underestimates," he said. The Israeli government is under mounting international and domestic pressure to end the war.

Does SA need a Covid-like ministerial advisory committee to deal with HIV funding cuts?
Increase health taxes. Roll out the twice-a-year anti-HIV jab lenacapavir to stop HIV from spreading. Use artificial intelligence (AI) to do more with less. Convene a ministerial advisory committee. These are some of the things that have surfaced as potential solutions to fill the huge gap that US President Donald Trump's administration's sudden funding cuts in February have left. But would they work — and are they doable? Only if we move fast, and get lots of each thing, it seems. Health minister Aaron Motsoaledi told Bhekisisa's TV show, Health Beat, in July, that he 'would strongly consider' a ministerial advisory committee (MAC), like the one we had during the Covid pandemic for which scientists advised the health department on what to do. 'There's nothing wrong with establishing a MAC [to deal with funding cuts],' Motsoaledi admitted ... but we've not yet established anything like that for [the funding crisis].' No MAC or emergency think-tank with input beyond government structures has since been announced by the health department. But scientists warn such a committee should be an important part of the country's response to the crisis. 'We need to urgently convene a national think-tank,' medical doctor and the head of Wits RHI, Helen Rees, cautions. 'There are some really superb people who've been working in the programmes closely and well with the health department who could contribute their ideas and experience ... [and help figure out] what [strategies] can we [the health department] retain that aren't hugely expensive.' In Johannesburg, research released at the Conference on HIV Science in Kigali in July, shows HIV testing between January and March 2025 was 8.5% lower than the same time last year (before the funding cuts), and 31% less people were diagnosed with HIV in 2025. During the same period, there was also a 30% reduction in people who tested positive, who started on antiretroviral treatment, compared to 2024. So what has South Africa done so far? Motsoaledi has managed to raise a small amount of extra funding — R735m — from the treasury through the Public Finance Management Act. But it's less than 10% of the R7.9bn we've lost (and are in all likelihood about to lose in September, the end of the US financial year). The country is, however, starting to make progress with the rollout of lenacapavir, an injection that is taken once every six months, that provides near complete protection against HIV infection. About 170,000 people got newly infected with HIV in 2024, according to the latest Joint UN Programme on HIV and Aids report. A modelling study has shown if between two- and four-million people in the country take the jab, each year, for the next eight years, South Africa could end Aids as a public health threat by 2032. South Africa's medicines regulator, the South African Health Products Regulatory Authority, has told Bhekisisa the shot will be registered in the country before the end of the year. And, at a presentation at the Kigali conference, health department consultant Hasina Subedar said, if all goes well, the department will start to roll out the jab in April 2026. In July, the health department accepted an offer from the Global Fund for Aids, TB and Malaria, to reallocate R520m of its funds to buy lenacapavir from its maker, Gilead Sciences, over the next three years until cheaper generic versions become available. The funds will become available in October. But, if the health department budgets for the $60 per patient per year that the Global Fund has told them to, the grant is only enough to put about 400,000 people on preventive treatment for three years — about 10% of what is needed to end Aids by 2032. One more way to generate 'a stable and predictable funding stream' without donors, according to a July report by the public health organisation Vital Strategies, is to increase taxes on tobacco, alcohol and sugary drinks to a level where taxes constitute 50% of the selling price of the products. That money can then be used, among other things, to improve health infrastructure. According to the report, 45.7% of the price of a box of cigarettes, 27.6% of a bottle of beer and 3.4% of sugar-sweetened carbonated drinks currently go towards taxes in South Africa. Mia Malan recently asked Wits RHI's Helen Rees how the country should go about to find solutions to the HIV and TB funding crisis. Following is an edited version of the full TV interview.
