China grapples with outbreak of deadly mosquito-borne virus
The city of Foshan in Guangdong province has been particularly hard-hit, with reported cases of chikungunya fever soaring to 4,014 by Friday.
This marks a rapid escalation since authorities began tracking the infection just two weeks prior, according to public records from local health departments.
Sun Yang, deputy director of the National Center for Disease Control and Prevention, described the outbreak as "quite severe" during a news conference in Foshan on Wednesday.
The World Health Organisation states that chikungunya, transmitted by infected mosquito bites, typically causes fever and severe joint pain, though fatalities are uncommon.
In response, the Chinese Center for Disease Control and Prevention has issued advisories for preventing both chikungunya and dengue fever, another mosquito-borne illness.
Recommendations include using physical barriers like screen doors and mosquito nets, alongside applying repellent to exposed skin. The CDC also noted the epidemic was "imported," without disclosing its origin.
The Chinese agency also called for people who have symptoms like fever, rash and joint pain to see a doctor.
Shunde district in Foshan, where 90 per cent of the cases are located, is famous for its Cantonese food, and sees many visitors each year.
Patients who tested positive for chikungunya fever stayed in hospital beds covered by mosquito nets, according to photos shown on state-run broadcaster CCTV.
Local media reports said on Thursday that local authorities had almost doubled the number of mosquito-proof isolation beds to 7,220 to meet the growing demand.
Authorities in Guangdong are urging residents to make sure there's no standing water in their homes, such as in flowerpots, coffee machines or spare bottles.
The Health Commission in Foshan stated on Thursday that a fine of up to 10,000 yuan ($1,400) could be applied if violations are found.
The Beijing CDC said on Tuesday that the city occasionally experiences imported cases of chikungunya fever.
There are two chikungunya vaccines that have received regulatory approvals in several countries and/or have been recommended for use in populations at risk, but the vaccines are neither widely available nor in widespread use, according to WHO.
China had its first chikungunya spike in 2010 with 253 cases in Dongguan, a nearby city in the same province, according to the Guangdong provincial CDC. Several cases were found in years since then, but they weren't widespread.
The country's first case was imported in 1987, according to research papers and media reports.

Millions of people are suffering from brain fog. A new study will find out why
Millions of people who recover from infections like COVID-19, influenza and glandular fever are affected by long-lasting symptoms. These include chronic fatigue, brain fog, exercise intolerance, dizziness, muscle or joint pain and gut problems. And many of these symptoms worsen after exercise, a phenomenon known as post-exertional malaise. Medically the symptoms are known as myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS). The World Health Organization classifies this as a post viral fatigue syndrome, and it is recognised by both the WHO and the United States Centers for Disease Control and Prevention as a brain disorder. Experiencing illness long after contracting an infection is not new, as patients have reported these symptoms for decades. But COVID-19 has amplified the problem worldwide. Nearly half of people with ongoing post-COVID symptoms – a condition known as long-COVID – now meet the criteria for ME/CFS. Since the start of the pandemic in 2020, it is estimated that more than 400 million people have developed long-COVID. To date, no widely accepted and testable mechanism has fully explained the biological processes underlying long-COVID and ME/CFS. Our work offers a new perspective that may help close this gap. Our research group studies blood and the cardiovascular system in inflammatory diseases, as well as post-viral conditions. We focus on coagulation, inflammation and endothelial cells. Endothelial cells make up the inner layer of blood vessels and serve many important functions, like regulating blood clotting, blood vessel dilation and constriction, and inflammation. Our latest review aims to explain how ME/CFS and long-COVID start and progress, and how symptoms show up in the body and its systems. By pinpointing and explaining the underlying disease mechanisms, we can pave the way for better clinical tools to diagnose and treat people living with ME/CFS and long-COVID. What is endothelial senescence? In our review, our international team proposes that certain viruses drive endothelial cells into a half-alive, 'zombie-like' state called cellular senescence. Senescent endothelial cells stop dividing, but continue to release molecules that awaken and confuse the immune system. This prompts the blood to form clots and, at the same time, prevent clot breakdown, which could lead to the constriction of blood vessels and limited blood flow. By placing 'zombie' blood-vessel cells at the centre of these post-viral diseases, our hypothesis weaves together microclots, oxygen debt (the extra oxygen your body needs after strenuous exercise to restore balance), brain-fog, dizziness, gut leakiness (a digestive condition where the intestinal lining allows toxins into the bloodstream) and immune dysfunction into a single, testable narrative. From acute viral infection to 'zombie' vessels Viruses like SARS-CoV-2, Epstein–Barr virus, HHV-6, influenza A, and enteroviruses (a group of viruses that cause a number of infectious illnesses which are usually mild) can all infect endothelial cells. They enable a direct attack on the cells that line the inside of blood vessels. Some of these viruses have been shown to trigger endothelial senescence. Multiple studies show that SARS-CoV-2 (the virus which causes COVID-19 disease) has the ability to induce senescence in a variety of cell types, including endothelial cells. Viral proteins from SARS-CoV-2, for example, sabotage DNA-repair pathways and push the host cell towards a senescent state, while senescent cells in turn become even more susceptible to viral entry. This reciprocity helps explain why different pathogens can result in the same chronic illness. Influenza A, too, has shown the ability to drive endothelial cells into a senescent, zombie-like state. What we think is happening We propose that when blood-vessel cells turn into 'zombies', they pump out substances that make blood thicker and prone to forming tiny clots. These clots slow down circulation, so less oxygen reaches muscles and organs. This is one reason people feel drained. During exercise, the problem worsens. Instead of the vessels relaxing to allow adequate bloodflow, they tighten further. This means that muscles are starved of oxygen and patients experience a crash the day after exercise. In the brain, the same faulty cells let blood flow drop and leak, bringing on brain fog and dizziness. In the gut, they weaken the lining, allowing bits of bacteria to slip into the bloodstream and trigger more inflammation. Because blood vessels reach every corner of the body, even scattered patches of these 'zombie' cells found in the blood vessels can create the mix of symptoms seen in long-COVID and ME/CFS. Immune exhaustion locks in the damage Some parts of the immune system kill senescent cells. They are natural-killer cells, macrophages and complement proteins, which are immune molecules capable of tagging and killing pathogens. But long-COVID and ME/CFS frequently have impaired natural-killer cell function, sluggish macrophages and complement dysfunction. Senescent endothelial cells may also send out a chemical signal to repel immune attack. So the 'zombie cells' actively evade the immune system. This creates a self-sustaining loop of vascular and immune dysfunction, where senescent endothelial cells persist. In a healthy person with an optimally functioning immune system, these senescent endothelial cells will normally be cleared. But there is significant immune dysfunction in ME/CFS and long-COVID, and this may enable the 'zombie cells' to survive and the disease to progress. Where the research goes next There is a registered clinical trial in the US that is investigating senescence in long-COVID. Our consortium is testing new ways to spot signs of ageing in the cells that line our blood vessels. First, we expose healthy endothelial cells in the lab to blood from patients to see whether it pushes the cells into a senescent, or 'zombie,' state. At the same time, we are trialling non‑invasive imaging and fluorescent probes that could one day reveal these ageing cells inside the body. In selected cases, tissue biopsies may later confirm what the scans show. Together, these approaches aim to pinpoint how substances circulating in the blood drive cellular ageing and how that, in turn, fuels disease. Our aim is simple: find these ageing endothelial cells in real patients. Pinpointing them will inform the next round of clinical trials and open the door to therapies that target senescent cells directly, offering a route to healthier blood vessels and, ultimately, lighter disease loads.

Inside China's sick plot to build empire of ‘organ harvesting centres' in five years… with ‘donors' already lined up
CHINA'S regime is significantly expanding its empire of organ harvesting centres in a twisted bid to make money, experts say. A plot to build six new sites in Xinjiang Uyghur by 2030 has stoked fears of forced organ removal, given staggeringly low donation rates in the region. 4 4 China's organ trade is already estimated to have a market value of $1 billion per year - which the Communist government wants to swell. A liver transplant, for example, can cost around £118,000 ($160k) in China - but with a much shorter waiting time compared to the rest of the world. This draws in not only recipients from inside the sprawling nation, but also unsuspecting international visitors who travel there for a transplant. China's regime has long been accused of orchestrating a non-consensual organ harvesting campaign against persecuted minorities. Prisoners are known to be killed specifically for the extraction of their organs. Experts say the primary victims of forced organ harvesting are those who follow Buddhist qigong and meditation practice of Falun Gong. They also believe that incarcerated Uyghurs fall victim - and new facilities are planned to open in their autonomous region of Xinjiang. At least six transplant institutions are tipped to open in the next five years, which campaigners say is hugely disproportionate to Xinjiang's low organ donation rate. Xinjiang is understood to have an organ donation rate of just 0.69 per cent per million people - significantly below the national average of 4.66 per cent. It has raised questions among experts who fear it could be part of a sickening plot to use detained Uyghurs as a living organ "donation" bank. Ughur detainees have reported forced blood tests, ultrasounds and organ-focused medical scans while in custody. Insiders say such procedures are consistent with chilling organ compatibility testing. Wendy Rogers, Chair of the International Advisory Board of the International Coalition to End Transplant Abuse in China (ETAC), told the Sun: "The guise is that all the organs will come from voluntary donations. "But this is implausible given the reported rate of just 0.69 donors per million people in Xinjiang. "This massive expansion in Xinjiang - a region already under scrutiny for systematic repression - raises deeply troubling questions about where the organs will come from. 'There is simply no justification for such growth in transplant capacity given the region's official organ donation rate, which is far below the national average.' 'Plot to kill survivor' by Katie Davis, Chief Foreign Reporter (Digital) THE first known survivor of China's brutal organ harvesting scheme says the regime is plotting to kill him and stage his death as suicide. Cheng Peiming told how Xi Jinping 's communist party is on a mission to silence him after he helped expose its organ harvesting plot. He revealed how he was tortured and had parts of his liver and lung removed by Xi's stooges after being imprisoned for practicing the Falun Gong religion. Leaked insider information reveals China's security services and high-level Chinese Communist Party (CCP) leaders have taken notice - and have unleashed a plot to try and discredit, or even kill, Cheng. The CCP has said to "kill him directly and make it look like a suicide" if needed, according to bombshell information from an internal source. Cheng has faced several suspicious threats to his physical safety, including an early hours break-in of his home in New York in November. The intruder forced open the bolt on the garage door, left two doors open and left deep tyre marks in his backyard. Cheng believes the break-in was an attempt to intimidate and silence him after a series of other attacks. Up to 100,000 organ transplants are estimated to be carried out in China every year - with huge swathes harvested without consent. New facilities - which will triple the number in the region from three to nine - will offer heart, lung, liver, kidney and pancreas/ small intestine transplants. The Chinese government claimed back in 2015 that it had stopped using organs from executed prisoners - but no legal reforms were coupled with the announcement. Experts say sourcing organs from prisoners was never explicitly banned either. Rogers, who is a professor of Clinical Ethics, added: "We know that China is expanding its transplant capacity in Xinjiang, despite the relatively small population, low voluntary organ donation rates and existing capacity. "This doesn't make sense unless the hospitals involved are confident that there will be a steady supply of organs for transplantation. "In the absence of any other organ source, we believe that the organs will come from Uyghur and other minorities who are incarcerated in camps Xinjiang, and killed for their organs. "Organ transplantation generates a lot of income, so the motive may be financial." It comes after The Sun reported how China's government uses cash bribes and death threats in a warped intimidation crusade against critics. Leaked documents exposed a shocking escalation of attacks on whistleblowers and victims of a forced organ harvesting campaign orchestrated by the regime. Whistleblowers who attended a secret Chinese Communist Party (CCP) meeting have revealed information from inside Xi Jinping 's government. This and a dossier of evidence laid bare a multi-pronged scheme spearheaded by Xi to silence members of Falun Gong and other groups vocal about China's severe persecution. 4 4
