Protesters in Ivory Coast’s commercial capital, Abidjan, have destroyed a coronavirus centre that was being built in the district of Yopougon. Residents said it was being built in a crowded residential area, too close to their homes.

Videos on social media show people tearing apart the centre with their bare hands, smashing construction materials on the ground. Some appeared to be hurling metal poles into a truck. The health ministry said the building was never intended as a treatment centre, only as a testing facility.

Although, like many African countries, Ivory Coast has had relatively few confirmed coronavirus cases, it has imposed a lockdown in Abidjan and a nationwide curfew. On Saturday, health officials urged people to wear masks to try to slow the spread of the virus.The hostile response towards the testing centres is reminiscent of attitudes during Ebola outbreaks in West and Central Africa when some people attacked health workers, suspicious that they were bringing the disease to their communities, rather than offering crucial medical care.(BBC)…[+]

Data from atomic bomb tests conducted during the Cold War have helped scientists accurately age the world’s biggest fish. Whale sharks are large, slow moving and docile creatures that mainly inhabit tropical waters. They are long-lived but scientists have struggled to work out the exact ages of these endangered creatures.

But using the world’s radioactive legacy they now have a workable method that can help the species survival.

• Neanderthals ate sharks and dolphins
• Great whites ‘live for 70 years’
• Climate change clips the nightingale’s wings

Whale sharks are both the biggest fish and the biggest sharks in existence. Growing up to 18m in length, and weighing on average of about 20 tonnes, their distinctive white spotted colouration makes them easily recognisable.(BBC)…[+]

A four-year-old female Malayan tiger at the Bronx Zoo has tested positive for the coronavirus. The tiger, named Nadia, is believed to be the first known case of an animal infected with Covid-19 in the US. The Bronx Zoo, in New York City, says the test result was confirmed by the National Veterinary Services Laboratory in Iowa.

Nadia, along with six other big cats, is thought to have been infected by an asymptomatic zoo keeper. The cats started showing symptoms, including a dry cough, late last month after exposure to the employee, who has not been identified. “This is the first time that any of us know of anywhere in the world that a person infected the animal and the animal got sick,” Paul Calle, the chief veterinarian at the zoo, told Reuters news agency on Sunday. There have been isolated instances of pets testing positive for the coronavirus elsewhere in the world, but experts have stressed there is no evidence they can become sick or spread the disease. Mr Calle said he intends to share the findings with other zoos and institutions researching the transmission of Covid-19.(BBC)…[+]
