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neighbouring cities had ordered travellers from Foshan to undergo a 14-day home quarantine, but that has since been withdrawn.Some people have compared these measures to those imposed during the pandemic, and questioned their necessity.A user on Weibo wrote, "These feel so familiar...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.

China reports 7,000 cases of chikungunya virus
More than 7,000 cases of a mosquito-borne virus have been reported across China's Guangdong province since July, prompting measures similar to those taken during the Covid-19 pandemic. In Foshan city, which has been hit the hardest, chikungunya patients must stay in hospital, where their beds will protected with mosquito nets. They can only be discharged after they test negative or at the end of a week-long stay. Spread through the bite of an infected mosquito, the virus causes fever and severe joint pain, which sometimes can last for years. Although rare in China, chikungunya outbreaks are common in South and South East Asia and parts of Africa. How widespread are the infections in China?

Global outbreak fears surge as virus in China prompts quarantines and thousands of new cases are reported
Chinese officials announced Covid-like quarantines in some cities as cases of chikungunya virus continue to increase. Over 7,000 cases of the mosquito-borne virus have been reported across the southern city of Foshan in the Guangdong province of the country. Patients in the city are forced to stay in hospitals where their beds are covered with mosquito nets for a week or until they test negative, if sooner. No deaths have yet been reported. At least 12 other cities in Guangdong have reported infections, with about 3,000 cases being reported over the past week, bringing the total to over 10,000 in the country. Those experiencing fevers, joint pain or rashes are being asked to visit the nearest hospital so they can be tested for the virus in the country. Additionally, officials had ordered travelers from Foshan to undergo a 14-day home quarantine, similar to Covid restrictions, but that has since been withdrawn. Hong Kong also reported its first chikungunya case this week involving a 12-year-old boy who developed a fever, rash and joint pain after traveling to Foshan in July. The chikungunya virus is primarily spread by the Aedes mosquito species, and nearly half a million became infected between 2004 and 2005, leading to a worldwide epidemic. Diana Rojas Alvarez, a medical officer at the WHO, said of the new cases: 'We are seeing history repeating itself,' referencing the 2004-2005 outbreak. Chikungunya infections are most common in Asia, Africa and South America, though more recently cases have also emerged across Europe and the US. The virus can cause symptoms like fever, joint pain and life-threatening complications related to the heart and brain. The infection does not spread from person to person through bodily contact or saliva and can only be transmitted through a bite from an infected mosquito. Given the sudden increase in cases in China, the CDC has issued a travel advisory for Americans traveling to the country, urging them to exercise 'increased caution' following the outbreak. The federal agency is also asking Americans to ensure they have received both vaccinations against chikungunya. In late 2023, the FDA approved a vaccine for chikungunya for people over the age of 18 who are at increased risk of exposure to the virus called IXCHIQ. Similarly, another vaccine that mimics the effects of chikungunya in the body to build immunity, called VIMKUNYA, was also licensed in February 2025 for use in those aged 12 and above. These are not routine vaccines and are recommended to those traveling to areas with outbreaks or elevated risk and laboratory workers with potential exposure to the chikungunya virus. Experts are also asking people to regularly use insect repellents and wear long-sleeve clothing to prevent mosquito bites this summer. The current global surge began in early 2025, with major outbreaks in the Indian Ocean islands of La Reunion, Mayotte and Mauritius. According to the European Center for Disease Prevention and Control, there have been about 240,000 Chikungunya virus cases and 90 related deaths in 16 countries since the beginning of 2025 as of August 4. The virus has also spread to Madagascar, Somalia, Kenya and India and is making its way to Europe. Case counts have also been increasing in Samoa, Tonga, French Polynesia, Fiji and Kiribati. As of August 5, the CDC reports there have been 46 cases of chikungunya infections in the US that were contracted while traveling to high-risk areas. No deaths have yet been reported. While it remains unclear where patients contracted the virus, the federal agency has issued an elevated risk of exposure notice for Brazil, Colombia, India, Mexico, Nigeria, Pakistan, Philippines and Thailand and now China. Approximately 200 cases of the virus were reported in 2024 in the US. There are no reports on deaths. According to the CDC, chikungunya was rarely identified in American travelers before 2006. However, between 2006 and 2013, nearly 30 people tested positive for the infection every year in the US. All were travelers visiting or returning to the US from affected areas in Asia, Africa, or the Indian Ocean. In 2014, 2,799 cases, out of which 12 were locally acquired, were reported in various US states, including Florida, Texas, Puerto Rico, and the Virgin Islands, marking the year as the highest ever. Though not fatal, chikungunya can cause a range of effects, which are primarily marked by a sudden onset of fever and severe joint pain, while other common symptoms include muscle pain, headache, nausea, fatigue and rashes. While the acute phase of the illness usually resolves within a week or two, the joint pain can persist for weeks, months or even years in some individuals. However, in some cases, infections can progress to severe dengue, which can cause potentially life-threatening complications such as internal bleeding and organ damage, and death. In extreme cases, eye, heart and neurological complications have also been reported in people suffering from a chikungunya infection. Newborns, adults aged 65 and older and people with certain health conditions are also at risk of developing Type 2 diabetes, heart disease and high blood pressure due to an infection. While the virus cannot be transmitted directly from person to person, people can become infected with chikungunya when mosquitoes feed on an infected person and then bite them. If a pregnant woman is infected around the time of delivery, the baby can also be infected at birth, which often results in severe disease in the baby. While there is no medication to treat a chikungunya infection, its symptoms can be managed by taking acetaminophen for pain and drinking lots of fluids.

What to know about Legionnaires' disease, which has sickened dozens in New York City
An outbreak of Legionnaires' disease in New York City has killed two people and sickened 58 since late July. City health officials link the Central Harlem outbreak to cooling towers, structures containing water and a fan that are used to cool buildings. They said 11 of these towers initially tested positive for a type of bacteria that causes Legionnaires' disease, but the problem has been remedied. They urged people in the area with flu-like symptoms to contact a health care provider as soon as possible, especially if they are 50 or older, smoke or have chronic lung conditions. Here's what to know. What is Legionnaires' disease? It's a type of pneumonia caused by Legionella bacteria, which grow in warm water and spread in building water systems. They can be found in places such as showerheads, hot tubs and cooling towers. People often get the disease by inhaling aerosols from contaminated water. Hospital patients can also contract it through contaminated water or ice, and babies can be exposed during water births, health officials said. People don't get it from each other. Symptoms usually develop two days to two weeks after exposure and include cough, fever, headaches, muscle aches and shortness of breath, according to the U.S. Centers for Disease Control and Prevention. How does Legionnaires' disease hurt you and how can you treat it? It's important to be diagnosed quickly and treated with the appropriate antibiotics, health officials said. If untreated, the disease usually worsens during the first week, the World Health Organization said. Complications can include respiratory failure, shock and kidney or multi-organ failure. How can Legionnaires' disease be prevented? People responsible for the safety of buildings and water systems can reduce the threat by taking steps to minimize the growth of the bacteria, the WHO said. For example, they should regularly clean and disinfect cooling towers, maintain an adequate level of chlorine in spa pools and flush unused taps in buildings weekly. There are also steps people can take to reduce the risk of Legionnaires ' disease at home. New York state health officials suggest draining garden hoses; following manufacturers' instructions for cleaning and replacing water filters; checking chlorine levels in pools and hot tubs regularly and flushing hot water heaters twice a year. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education and the Robert Wood Johnson Foundation.
