Chikungunya virus: China reports 7,000 cases
How widespread are the infections in China?
Aside from Foshan, at least 12 other cities in the southern Guangdong province have reported infections. Nearly 3,000 cases were reported in the last week alone.On Monday, Hong Kong reported its first case - a 12-year-old boy who developed fever, rash and joint pain after traveling to Foshan in July.The virus is not contagious, and only spreads when an infected person is bitten by a mosquito that then goes on to bite others. Officials say all the reported cases have been mild so far, with 95% of the patients were discharged within seven days.Still, the cases have led to some panic, given the virus is not widely known in the country."This is scary. The prolonged consequences sound very painful," one user wrote on Chinese social media platform Weibo.The US has urged travellers to China to exercise "increased caution" following the outbreak.
What else is China doing to curb infections?
Authorities across Guangdong province have vowed to take "decisive and forceful measures" to stop the spread of the disease.Those with symptoms, such as fever, joint pain or rashes, are being urged to visit the nearest hospital so they can be tested for the virus.Authorities have instructed residents to remove stagnant water in their homes, such as in flowerpots, coffee machines or spare bottles - and warned of fines up to 10,000 yuan ($1,400) if they don't do this. They are also releasing giant "elephant mosquitoes" that can devour smaller, chikungunya-spreading bugs; and an army of mosquito-eating fish. Last week, officials in Foshan released 5,000 of these larvae-eating fish into the city's lakes. In parts of the city, they are even flying drones to detect sources of stagnant water.Some neighbouring cities had ordered travellers from Foshan to undergo a 14-day home quarantine, but that has since been withdrawn.Some people have compared these measures to those imposed during the pandemic, and questioned their necessity.A user on Weibo wrote, "These feel so familiar... But are they really necessary?" Another wrote: "What's the point of the quarantine? It's not as though an infected patient will then go around biting other people?" China implemented severe restrictions during the pandemic, including forcing people into quarantine camps and sealing residential buildings and whole neighbourhoods on short notice for days or even weeks.
What is chikungunya?
Most people bitten by an infected mosquito will develop symptoms of chikungunya within three to seven days.Apart from fever and joint pain, other symptoms include rash, headache, muscle pain and swollen joints. In most cases, patients will feel better within a week. In severe cases however, the joint pain can last for months or even years. Those at risk for more severe disease include newborns, the elderly, and people with underlying medical conditions, such as heart disease or diabetes.There is no cure, but deaths from chikungunya are rare.The virus was first identified in Tanzania in 1952. It then spread to other countries in sub-Saharan Africa and South East Asia. To date, it has been reported in more than 110 countries. The best way to prevent the virus from spreading is to reduce pools of stagnant water that allow the mosquitoes to breed, according to the World Health Organization.

Officials record first case in 30 YEARS of locally acquired mosquito-borne disease
New Jersey health officials reported what could be the first locally acquired case of a deadly mosquito-borne illness in the state in 34 years. Authorities are working to confirm if a malaria case in a Morris County resident, who has not traveled internationally, was contracted in the US. The concern surrounding the New Jersey case stems from the fear that the conditions for local transmission, an infected person, a local mosquito capable of carrying the parasite, and a susceptible public, may be converging to pose a potentially serious public health problem. Malaria is caused by a parasite endemic to tropical and subtropical regions globally, including parts of Africa, South Asia, and South America, and is transmitted through bites from Anopheles mosquitoes. Transmission from mosquitoes to people is a greater public health threat in those regions with warm, humid climates. However, rising temperatures across the US are creating more suitable environments for mosquitoes to thrive, increasing the potential for disease transmission. The New Jersey case indicates that infected mosquitoes are circulating locally. While the overall risk remains low, it is no longer zero. Public health officials are containing the threat, but personal precautions such as bug spray are increasingly necessary. A local malaria outbreak requires a specific sequence of events where a mosquito serves as the bridge between an infected traveler and a new, local person. The traveler likely recently arrived in New Jersey from a country where the parasite is endemic, carrying it into the US, where they were bitten by a local anopheles mosquito that then bit a Morris County resident. Each year, the US records roughly 2,000 travel-related malaria cases, resulting in five to 10 deaths. In New Jersey, about 100 such cases are diagnosed annually from returning travelers who were bitten by a mosquito that carried the parasite. If caught early, malaria can be cured with medication, but it can turn deadly very quickly if left untreated with antimalarial drugs. A 24-hour delay can increase the risk of death by one to five times. The unnamed Morris County, New Jersey resident had not traveled recently, but could have been bitten by a local Anopheles mosquito that picked up the malaria-causing parasite. Malaria spreads exclusively through the bite of an infected Anopheles mosquito. It is impossible to catch it from another person through everyday contact, such as touching or sharing food. Acting New Jersey Health Commissioner Jeff Brown said: 'While risk to the general public is low, it's important to take the necessary precautions to prevent locally acquired malaria in New Jersey. 'The most effective ways are to prevent mosquito bites in the first place and to ensure early diagnosis and treatment of malaria in returning travelers.' Locally acquired malaria is exceedingly rare. In 2024, Florida officials confirmed seven cases of malaria in Sarasota, the first in 20 years, most likely due to the presence of Anopheles mosquitoes and the reintroduction of the disease by travelers. And in 2023, a Texas resident who worked outdoors in Cameron County was diagnosed with malaria, the first locally acquired case there since 1994. That same year, a case of malaria was confirmed in Arkansas, and it was the first locally acquired case in the state in at least 40 years. Malaria causes flu-like symptoms such as fever, chills, and fatigue, appearing seven to 30 days after exposure. While curable with prescription drugs, it is fatal without prompt diagnosis and treatment. Even with treatment, mortality rates remain high, between 15 percent and 20 percent. It is a potentially fatal illness, especially for high-risk individuals, including young children, pregnant women, older adults, and those with a weakened immune system or no spleen. Caused primarily by the Plasmodium falciparum parasite, most common in Africa, malaria can lead to severe complications within hours of the first symptoms. Malaria causes severe illness by destroying red blood cells, a process that can rapidly deplete their numbers and lead to life-threatening anemia. A critical lack of oxygen-carrying cells prevents the body's muscles and organs from functioning properly, resulting in feelings of intense drowsiness, weakness, and faintness. A major killer of children under five in places where malaria is endemic is severe malarial anemia, which frequently demands blood transfusions. The complication drove an estimated 627,000 worldwide malaria deaths in 2020, primarily affecting young children in West Africa. Malaria can also cause severe neurological problems, most commonly cerebral malaria, as a result of infected red blood cells becoming sticky and clogging tiny blood vessels in the brain, blocking oxygen delivery. At the same time, the body's intense immune response damages the protective blood-brain barrier, causing it to leak fluid and leading to brain swelling. Beyond cerebral malaria, the illness can also trigger a range of other neurological complications, even after the initial infection has cleared, including Guillain-Barré syndrome, cerebellar ataxia, and a post-malaria neurological syndrome that can involve confusion, seizures, or psychosis. The CDC has dubbed the mosquito the world's deadliest animal. They spread an array of deadly diseases in addition to malaria, including dengue, West Nile, yellow fever, Zika, chikungunya and lymphatic filariasis, a parasitic infection in which adult worms live and reproduce in the lymphatic system. Their capacity to transmit a wide array of devastating illnesses, such as malaria, dengue, West Nile virus, yellow fever, Zika, and chikungunya, results in millions of global deaths every year.

Cholera epidemic sweeps Sudan killing 40 in just a week
Sudan is battling its worst cholera outbreak in years as hundreds of thousands of people fleeing violence crowd into unsanitary displacement camps. The outbreak, which is centred on Darfur in western Sudan, began last year but is now spreading at an unprecedented rate, said Adam Rojal, spokesperson of the General Coordination of Darfur Displaced People and Refugees organisation. Doctors Without Borders (MSF) said its teams in Darfur had resorted to treating people on the floors of its medical centres and had seen over 2,300 cholera patients in the last week alone. At least 40 people died, it added. Water shortages across Darfur have made it impossible to follow essential hygiene measures, such as washing dishes and food, said MSF. Most of the cases have been reported in Tawila, north Darfur, where hundreds of thousands of people are living in cramped displacement camps with little access to sanitation or clean water. In Tawila, people have to make do with an average of three litres of water a day for all their drinking, cooking and hygiene – less than half the emergency minimum of 7.5 litres recommended by the World Health Organisation (WHO), MSF said. Najla Adam Ahmed, a displaced person who is currently living in the Daba Nair camp in Tawila, told The Telegraph that people often have no choice but to drink from contaminated water sources. 'The water supply is very limited in some places and non-existent in others…with so many people, there is bound to be dirt everywhere,' she said. Sylvain Penicaud, an MSF project coordinator in Tawila, said: 'Just two weeks ago, a body was found in a well inside one of the camps. It was removed, but within two days, people were forced to drink from that same water again' Hawa Muhammad Mousa, 60, caught cholera and suffered diarrhoea, vomiting and a fever for six days. He said he feared he would die when he 'lost consciousness from the severity of the pain,' before he received treatment at a local health centre. 'The conditions are critical and very difficult,' said Mr Mousa, adding that the camp he's living in in Tawila has no toilets or sewage system. Cholera is caused by ingesting food or water contaminated by the bacterium Vibrio cholerae, which infects the intestines and makes them produce large quantities of fluid, leading to severe diarrhoea and vomiting. Death can come rapidly without treatment but it can be treated by replacing lost fluids and electrolytes with a mixture of sugars and salts dissolved in water, or intravenous fluids. There is also an effective vaccine. Photographs shared with The Telegraph from a camp in Jebel Marra, about 18 miles southwest of Tawila, show multiple cholera patients per bed, with others sprawled on metal benches. Sudan's civil war has been raging since April 2023, when violence erupted between Sudanese army chief General Abdel Farrah al-Burhan and his former deputy Mohamed Hamdan, the warlord better known as Hemedti, who leads the Rapid Support Forces (RSF) paramilitary group. In addition to the four million people who have now fled Sudan, a record 11.6 million people have been displaced within the country, about half of whom are in the Darfur region. The recent surge in cholera cases in Darfur has been driven by a fresh wave of internal displacement that came after the RSF launched a major attack on the Zamzam displacement camp, where famine was officially declared a year ago, and laid siege to the nearby city of El Fasher. Earlier this month Unicef estimated that the fighting in North Darfur had put over 640,000 children under the age of five at risk of hunger, violence and disease. More than 380,000 people who fled the violence have arrived in Tawila in recent months, straining already stretched healthcare in the camps there to breaking point. Sultanah Ismail Habib, 25, said she fled Zamzam camp 'at night in complete secrecy' with her five children when she heard 'the sound of intense gunfire in all directions'. She said she witnessed at least 20 people being killed by the RSF and many more dying of hunger and thirst on the 46-mile trek to Tawila. 'It was very difficult, and I had no means of transportation,' she told The Telegraph. Adam Omar Hussein Abdullah, 38, said he couldn't sleep for three days after the RSF attacked and only reached Tawila with 'great effort and humiliation'. RSF fighters beat him and stole all his belongings on the journey. 'I've lost everything in this war,' he said. Haja Youssef Saeed, 35, was trapped in El Fasher for six months before the 'abundance of disease and famine' pushed her to travel to Tawila with her children by donkey and on foot. Ms Saeed said she saw many people dying from starvation in El Fasher, which is the Sudanese Army's last stronghold in the region, adding that people had resorted to eating animal feed to stay alive. 'We wash it with water and eat it when we feel hungry,' she said. 'There is no such thing as feeling full in El Fasher.' The situation is not much better in Tawila, and she said she and her three children hadn't eaten since she arrived in the town three days earlier. In Tawila, heavy rains are deepening the crisis by destroying what little sewage infrastructure there is, leading to further contamination of the water supply. Tuna Turkmen, MSF's head of mission in Sudan, said the situation was 'beyond urgent,' with cases now 'spreading well beyond displacement camps' and across Darfur and the rest of the country. Sudan has reported nearly 100,000 suspected cases of cholera and more than 2,400 deaths since the outbreak was first declared more than a year ago. Experts have warned that the epidemic has already spread into neighbouring countries. In bordering Chad, 16 deaths and 288 cases were reported in the second week of August and South Sudan is also grappling with the 'worst and longest' cholera outbreak in its history. Mr Turkman called on the Ministry of Health, Unicef and the WHO to launch an emergency international response 'at a pace that matches the urgency this catastrophic situation requires.' 'Every day of delays costs lives…Survivors of war must not be left to die from a preventable disease,' he said.
