Q: Paragraph: The airline had earlier said only cabin crew operating mainland China flights could wear masks, in response to the airline’s flight attendants calling for permission to wear masks on all flights globally as cases have also been confirmed in the United States, Thailand, South Korea, Japan and Taiwan. “Due to the evolving information from health authorities, we will allow crew members and frontline airport employees to wear surgical face masks when on duty at their discretion,” Cathay said in a statement. The coronavirus outbreak, which began in the central Chinese city of Wuhan, struck as millions of Chinese prepared to travel for the Lunar New Year, heightening contagion risks. Wuhan’s local government said it would close all urban transport networks and suspend outgoing flights from the city as of 10 a.m. on Thursday (0200 GMT), state media reported, adding that the government said citizens should not leave the city unless there were special circumstances. The Cathay Pacific Airways Flight Attendants Union said on Tuesday it had received a “tremendous” amount of emails and messages from members concerned over catching the virus given they are exposed to over 300 passengers from numerous places on a single flight. On Wednesday evening, Cathay said on its website that rebooking, rerouting and refund charges would be waived for all tickets booked on or before Jan. 21, arriving to or departing from Wuhan through March 31, an extension from the Feb. 15 date listed the prior evening. Deaths from China’s new flu-like virus rose to 17 on Wednesday, with more than 540 cases confirmed. The virus has already spread beyond Wuhan to population centers including Beijing, Shanghai, Macau and Hong Kong. Cathay said that as required by the Hong Kong health authorities, it was distributing health declaration forms and will be making face masks and antiseptic wipes available at the boarding gate to passengers traveling from Wuhan to Hong Kong. “Our frontline staff are reminded to maintain good personal and environmental hygiene, and to remain alert and vigilant while being on the lookout for passengers presenting with infectious disease symptoms,” the airline said. Cathay has already been hit by plummeting demand as a result of anti-government protests in Hong Kong, leading it to cut capacity and defer the delivery of four planes. Shares in Cathay have fallen by 10% since the start of January as the virus spread. Jefferies analysts said shares in Cathay and mainland Chinese carriers could remain under pressure for some time if the coronavirus situation paralleled the 2003 SARS outbreak and cases continued to increase. That coronavirus outbreak killed nearly 800 people. Claim: Cathay to let crew wear masks on all flights due to new coronavirus.

A: Hong Kong’s Cathay Pacific Airways Ltd (0293.HK) will allow all crew members and frontline employees to wear surgical masks due to concerns over a new coronavirus, and said passengers to and from Wuhan, China, could change or cancel flights for free through March 31.

Q: Paragraph: In the interview, Bolsonaro also stuck to the government’s assertion that a Greek freighter caused the oil spill scattered across beaches along 1,300 miles (2,100 kilometers) of coastline even after the shipowner’s denial of any leakage from its vessel. “All signs point to this Greek cargo ship. All of them,” he told Record TV, adding that the leak, “by all accounts looks like it was criminal.” Brazil’s government has been striving to investigate the cause of the spill that has hit 321 beaches along the northeast coast since early September, hurting fishing and tourism. Authorities have described the spill as one of the country’s worst environmental disasters. The crude’s density renders it invisible from above, making it hard to track its origin or to have a clear picture of the amount of oil yet to reach Brazil’s coast. Some 4,000 tons of oil has been collected from northeastern beaches thus far, according to a statement Sunday from the Navy, Brazil’s environmental regulator, and the national petroleum agency. “To say how much oil there still is very difficult to say,” Commander Leonardo Puntel of the Brazilian Navy said at a press conference on Monday. “Since the oil is underwater, we don’t know if there’s still a lot or a little. There is effectively no correct and accurate way to monitor these oil spots,” he said, adding that they have seen a decrease in oil arriving onto beaches in recent days. He called the disaster “unprecedented.” “There is no case in the world of a large-scale oil spill where the origins are totally unknown. This case has no parallel, we don’t know who polluter is,” Puntel said. Brazil’s defense minister, Gen. Fernando Azevedo e Silva, also stressed how challenging it is to calculate the spill’s scope. “It is not detectable by satellite. ... It is imperceptible. We do not know how much will still come,” he said. David Zee, an oceanographer at the State University of Rio de Janeiro, said that the 4,000 tons of collected oil is “just the tip of the iceberg,” both because the cleanup effort is mostly limited to sandy beaches in populated areas and also because a large portion of spilled oil is likely spread deep beneath the ocean’s surface. Furthermore, when currents bring oil to sandy shores, it is relatively easy to collect, while is nearly impossible to remove from corals and mangrove forests, which make up part of the affected area, Zee said. Brazilian prosecutors have named Greek shipping company Delta Tankers Ltd as a suspect of the leak’s origins. The company issued a statement earlier saying it found no evidence of leakage after reviewing the ship’s cameras and sensors. “This material will be willingly shared with Brazilian authorities, should they contact the company regarding this investigation. So far, no such contact has been made,” the statement said. Federal Police officer Franco Perazzoni said at Monday’s press conference that the company will be officially notified via Interpol. Brazilian prosecutors said previously that Delta’s oil tanker, named Bouboulina, was navigating through Brazilian waters at the time and location of the spill. The ship was carrying oil from Venezuela to Malaysia. In a search order seen Friday by The Associated Press, Brazilian prosecutors said “there is no indication of another boat” that could have discharged the Venezuelan crude into the sea. Brazilian armed forces along with environmental protection agencies and petroleum authorities are leading an operation to clean, monitor and investigate the oil spill. Several public universities are conducting research about the spill’s origins and impact. Television footage has also shown volunteers flocking to beaches to help with the cleanup, often without government supervision. Of particular concern at the moment is the Abrolhos national marine park, home to Brazil’s largest coral reefs. Authorities said Sunday night that they had removed the fragments of oil that had appeared in the park and so far no new traces had been found. “A very small amount of oil arrived on November 2, on November 3 only a few fragments remained, today there’s none,” Puntel said in the Monday press conference. “Will more oil fragments come? Maybe.” Claim: Brazil reckons with new oil spill mystery: When will it end?.

A: Brazilian authorities said on Monday that they have no way of knowing how much more oil will wash ashore the country’s northeastern coast, despite President Jair Bolsonaro’s ominous warning during a Sunday night TV interview that “the worst is yet to come.”
