Sydney, April 17: A person has died and 12 others have been infected after contracting Legionnaires’ disease in an outbreak linked to central Sydney, the Department of Health in the Australian state of New South Wales said on Thursday.

There are now 12 confirmed cases of Legionnaires’ disease in people who spent time in central Sydney between March 13 and April 5, up from the six cases that had been diagnosed as of April 10, the department said.

It said that one of the confirmed cases died in the hospital. Of the 12 reported cases, 11 have been hospitalised for treatment.

NSW Health on Thursday urged anyone who spent time in central Sydney and surrounding areas in late March or early April to be aware of symptoms of Legionnaires’ disease, including fever, chills, a cough and shortness of breath.

Legionnaires’ disease is a form of pneumonia caused by infection with Legionella bacteria, which is found naturally in fresh water. NSW Health said that symptoms can develop up to 10 days after exposure, Xinhua news agency reported.

“Outbreaks sometimes occur when bacteria from environmental sources such as cooling towers atop large buildings become contaminated,” Vicky Sheppeard, director of the southeast Sydney local public health unit, said in a statement.

“NSW Health continues to work closely with the City of Sydney to identify, inspect and sample any cooling towers in the CBD potentially implicated in the outbreak. To date, over 165 cooling towers have been inspected and tested,” she said.

According to the World Health Organisation, the Legionnaires’ disease mortality rate can be as high as 80 per cent in untreated immunosuppressed patients.

Most people catch Legionnaires’ disease by inhaling the bacteria from water or soil. Older adults, smokers, and people with weakened immune systems are particularly susceptible to Legionnaires’ disease.

Although Legionnaires’ disease primarily affects the lungs, it occasionally can cause infections in wounds and in other parts of the body, including the heart.

A mild form of Legionnaires’ disease — known as Pontiac fever — can produce fever, chills, headache and muscle aches. Pontiac fever doesn’t infect your lungs, and symptoms usually clear within two to five days.

London, April 17: The number of days each year that the world’s oceans experience extreme surface heat has tripled over the past 80 years due to global warming, a new study has found.

Researchers found that, on average, the global sea surface saw about 15 days of extreme heat annually in the 1940s, Xinhua news agency reported.

Today that figure has soared to nearly 50 days per year, revealed the study published in the journal Proceedings of the National Academy of Sciences.

Global warming is responsible for almost half of the occurrence of marine heatwaves — periods when sea surface temperatures rise well above normal for an extended time.

The study, produced by a team of scientists from the Mediterranean Institute for Advanced Studies, the University of Reading, the International Space Science Institute, and the University of the Balearic Islands, also found that rising global temperatures are making extreme ocean heat events last longer and become more intense.

“Marine heatwaves can devastate underwater ecosystems. Extended periods of unusually warm water can kill coral reefs, destroy kelp forests, and harm seagrass meadows,” said Xiangbo Feng, a co-author of the study at the National Centre for Atmospheric Science at the University of Reading.

The impacts of marine heat waves extend beyond the ocean. The researcher warns that increased marine heatwaves could, in return, cause our atmosphere less stable leading to more frequent and powerful tropical storms in some regions.

“As global temperatures continue to rise, marine heatwaves will become even more common and severe, putting increasing pressure on already stressed ocean ecosystems. These increased marine heatwaves could, in return, cause our atmosphere less stable leading to more frequent and powerful tropical storms in some regions,” Feng said

Noting that human activities are fundamentally changing oceans, the study called for urgent climate action to protect marine environments.

Beijing, April 17: A Chinese foreign ministry spokesperson said on Thursday that the United States’ 245 per cent tariff on certain products from China no longer makes economic sense.

It the US continues to play the “tariff numbers game”, it will pay no attention to it, according to the spokesperson, Xinhua news agency reported.

The statement came in the wake of White House’s statement that China faces tariffs of up to 245 per cent due to its retaliatory action.

China now faces up to 245 per cent tariffs on imports to the US as a result of its retaliatory tariffs, according to the White House Fact sheet.

This came after Beijing ordered its airlines not to take any further deliveries of Boeing jets in response to the earlier US decision to impose 145 per cent tariffs on Chinese goods.

According to the White House, the US President is open to making a trade deal with China, but Beijing should make the first move.

“More than 75 countries have already reached out to discuss new trade deals. As a result, the individualised higher tariffs are currently paused amid these discussions, except for China, which retaliated,” it said.

The White House also accused Beijing of banning exports to the US of gallium, germanium, antimony, and other key high-tech materials with potential military applications.

There are no winners in a trade conflict and the tussle between China and the US raises the risk of economic and geopolitical fallout, a report by S&P Global Ratings said this week.

Home to sizable manufacturing activities, Asia-Pacific is highly dependent on exports to the U.S. and China for growth. At the same time, Asia-Pacific depends on the US mostly for security.

The region could find itself pushed to take sides or walk a delicate line between the two large economies, the report stated.

To counteract tariffs, Asia-Pacific governments are exploring the formation of regional trade blocs or bilateral trade agreements. These efforts could accelerate, expediting the need to relocate supply sources and production.

China’s economic growth is seeing rising downside risk amid rising trade tensions with the US as its export engine falters from weaker global demand. The country’s domestic growth engine remains subdued, given the lingering real estate crisis, which is dragging down confidence.
