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.

E. coli outbreak in Florida linked to raw milk
Public health officials are warning of an outbreak of Campylobacter and E. coli-related complications linked to the consumption of raw milk from a Florida farm. The raw milk outbreak has impacted 21 people, including six children under the age of 10, causing seven hospitalizations, according to the Florida Department of Health. Two people have faced 'severe complications,' the department added. 'Sanitation practices in this farm are of particular concern due to the number of cases,' the department said in an announcement on Monday, though it did not name the particular facility. The Independent has contacted the department for more information. Raw milk can only be sold for non-human consumption in the state though some skirt the rule and buy milk meant for pets or animal feeds for their personal use. Florida officials warned that poor 'sanitation practices' at a dairy farm in the state were raising concerns after raw milk from the facility was tied to 21 cases of health impacts (Getty) The Department of Agriculture has banned the sale of raw milk for human consumption across state lines since 1987 and federal public health officials warn that consuming the unpasteurized milk puts people at risk of exposure to germs including Campylobacter, Cryptosporidium, E. coli, Listeria, Brucella, and Salmonella. The risk is especially high for children, the elderly, pregnant people, and those with compromised immune systems. 'Pasteurized milk offers the same nutritional benefits without the risks of raw milk consumption,' according to the CDC. 'Since the early 1900s, pasteurization has greatly reduced milk-borne illnesses.' 'While the perceived nutritional and health benefits of raw milk consumption have not been scientifically substantiated, the health risks are clear,' the FDA notes on its website. 'Since 1987, there have been 143 reported outbreaks of illness – some involving miscarriages, still births, kidney failure and deaths – associated with consumption of raw milk and raw milk products that were contaminated with pathogenic bacteria such as Listeria, Campylobacter, Salmonella, and E. coli.' Last year, California regulators recalled batches of raw milk from a Fresno farm after bird flu was detected in samples. HHS Secretary Robert F. Kennedy Jr. drinks raw milk and has called for expanding access, despite warnings, including from federal health officials, that unpasteurized dairy can carry dangerous bacteria (REUTERS) Despite the scientific consensus on the risks of unpasteurized milks recent years have seen raw milk take on a countercultural status and become popular among some conservatives and independents. Health and Human Services Secretary Robert F. Kennedy Jr. has said he only drinks raw milk, and raw milk backers within his Make American Healthy Again push were initially encouraged as Kennedy put raw milk on a wish list of foods and health-related topics he hoped to tackle in office. Since taking office, Kennedy's FDA temporarily halted a quality control program for testing milk amid Trump administration staffing cuts at the health department, but the secretary hasn't delivered the kind of changes to federal milk regulation they were hoping. Mark McAfee of Raw Farm, a California dairy that counted Kennedy as a customer, has said he was initially encourage by Kennedy and his allies to assist federal officials with changing raw milk rules, but was later rebuffed when he sought a meeting with regulators. 'That's a bait and switch and that is really quite sad,' he told the Fresno Bee last month.

Warning over skin cleansing wipes not marked as ‘sterile' after three brands spark outbreak of life-threatening bacteria
HEALTH chiefs are warning Brits to urgently dispose of three types of skin cleansing wipes after they were linked to outbreaks of life-threatening bacteria. An investigation by the UK Health Security Agency (UKHSA) found three brands of non-sterile wipes to be contaminated with Burkholderia stabilis bacteria. 3 Fifty-one people were confirmed to have been affected by the outbreak in the UK between 2018 and 2025. Though it hasn't caused any deaths, "there have been some serious infections which have required hospital treatment", the UKHSA said. Officials now suspect the cases were linked to specific skin wipe brands. UKHSA advised people who've bought affected wipes for 'skin cleansing' and wound cleaning purposes to stop using them and bin them immediately to avoid contamination. Bacteria was found in the following products: ValueAid Alcohol Free Cleansing Wipes Microsafe Moist Wipe Alcohol Free Steroplast Sterowipe Alcohol Free Cleansing Wipes The wipes are alcohol-free and not marked as 'sterile' - meaning they aren't completely free of germs. Testing also revealed contamination of Reliwipe Alcohol Free Cleansing Wipes, although not with the Burkholderia strain linked to the outbreak. Packs of the wipes have been pulled from shelves and are no longer for sale. The UKHSA also issued a safety alert to health professionals about recent infections potentially being linked to contaminated wipes to help keep patients safe. But UKHSA warned that wipes may also have been included in first aid kits. It urged customers to look through first aid kits and check packs they already have in their homes. Burkholderia stabilis is a bacteria found in natural environments and rarely causes infection in healthy people. The bug poses only a low risk to the general population, the UKHSA said. But people with weakened immune systems and cystic fibrosis, or those who use intravenous lines at home, are at higher risk of infection. Dr James Elston, consultant in epidemiology and public health at UKHSA, said: "While the overall risk to the public remains very low, a number of non-sterile alcohol-free wipe products have been linked to an outbreak of Burkholderia stabilis. "It is important these types of wipes are not used for the treatment of injuries, wounds, or broken skin, and that they are not used to clean intravenous lines." If you have used non-sterile wipes, you don't have to get medical help unless you have symptoms of: A wound infection, which can include redness, swelling, increased pain, warmth around the wound and pus An intravenous line infection, which can include signs such as redness, swelling, or pain around the insertion site and or fever and chills The health watchdog stressed that other non-sterile, alcohol-free wipes not included in the alert shouldn't be used for treating injuries, wounds or on broken skin anyway, as "their safety cannot be guaranteed". How to clean wounds, cuts and grazes You can treat a cut or graze yourself by stopping any bleeding, cleaning the wound, and covering it with a plaster or dressing. This will help stop it getting infected. What to do if the wound is bleeding a lot Check the wound and make sure there's nothing stuck in it. If there's nothing in the wound, put pressure on it using a bandage or a clean, folded cloth (such as a tea towel) for 10 minutes. If there's something stuck in the wound, do not try to take it out. Make sure not to press down on the object. Press firmly either side of it to push the edges of the wound together. If the wound is on your hand or arm, raise it above your head. If the wound is on your lower limb, lie down and raise it above the level of your heart. This will help reduce the blood flow. When the bleeding has stopped, firmly wrap a new bandage over the first cloth or bandage. If the wound keeps bleeding, leave the first bandage in place and add another one. Keep pressing firmly on the wound for another 10 minutes. How to clean and dress a cut or graze If the bleeding has stopped, you can clean a small wound and then put a plaster or dressing over it. Wash your hands thoroughly and dry them. Put on disposable gloves if you have some. Clean the wound by rinsing it with bottled or tap water, or by using sterile wipes. Clean the skin around the wound using soap and water or antiseptic – but try not to get antiseptic into the wound. Pat the area dry using a gauze swab or a clean tea towel. Put on a sterile dressing or a plaster. Keep the dressing clean by changing it as often as you need. You can take it off after a few days, once the wound has closed. Source: NHS Dr Alison Cave, the Medicines and Healthcare products Regulatory Agency's (MHRA) chief safety officer, said: "We consider wipes which are intended for a medical purpose to be medicines. "These products do not have a medicines authorisation. "Anyone who has used alcohol-free wipes and has concerns about potential infection is advised to speak with a healthcare professional." UKHSA stressed that you should only use wipes marked as 'sterile' on broken skin such as wounds, scratches, or where you can see blood, to reduce the chances of germ entering the body and causing infections
