HONG KONG (AP) — Pet cats and dogs cannot pass the new coronavirus on to humans, but they can test positive for low levels of the pathogen if they catch it from their owners. That's the conclusion of Hong Kong's Agriculture, Fisheries and Conservation Department after a dog in quarantine tested weakly positive for the virus Feb. 27, Feb. 28 and March 2, using the canine's nasal and oral cavity samples. A unidentified spokesman for the department was quoted in a news release as saying. "There is currently no evidence that pet animals can be a source of infection of COVID-19 or that they become sick." Scientists suspect the virus known as SARS-CoV-2 that causes the disease originated in bats before passing it on to another species, possibly a small wild mammal, that passed it on to humans. However, experts from the School of Public Health of The University of Hong Kong, the College of Veterinary Medicine and Life Sciences of the City University of Hong Kong and the World Organisation for Animal Health (OIE) have unanimously agreed that the dog has a low-level of infection and it is "likely to be a case of human-to-animal transmission." The dog, and another also in quarantine which has tested negative for the virus, will be tested again before being released. The department suggested any pets, including dogs and cats, from households where someone has tested positive for the virus should be put into quarantine. In general, pet owners should maintain good hygiene, including washing hands before and after handling animals, their food and supplies and no kissing them. People who are sick should avoid contact with pets and a veterinarian's advice should be sought if changes in a pet's health conditions are detected. "Apart from maintaining good hygiene practices, pet owners need not be overly concerned and under no circumstances should they abandon their pets," the spokesman said. 1919

Former US diplomat Joe Wilson, who challenged the Bush administration on the reasons to go to war with Iraq, has died of organ failure.Wilson's death was confirmed by his former wife, ex-CIA officer Valerie Plame.Wilson was the last American government official to meet with Saddam Hussein.In July 2003, Wilson wrote in a New York Times op-ed that in the months before the Iraq war "some of the intelligence related to Iraq's nuclear weapons program was twisted to exaggerate the Iraqi threat." Plame's work for the CIA was reported in the media not long afterward.Plame is now running for Congress in New Mexico. 625

Federal officials on Wednesday banned electrical shock devices used to discourage aggressive, self-harming behavior in patients with mental disabilities.The announcement from the Food and Drug Administration follows years of pressure from disability rights groups and mental health experts who have called the treatment outdated, ineffective and unethical. The agency first announced its intent to ban the devices in 2016.For years, the shock devices have been used by only one place in the U.S., the Judge Rotenberg Educational Center of Canton, Massachusetts, a residential school for people with autism and other psychiatric, developmental or mental disabilities. The FDA said Wednesday it estimates 45 to 50 people at the school are currently being treated with the device.School administrators have called the shocks a last resort to prevent dangerous behaviors, such as head-banging, throwing furniture or attacking teachers or classmates. The center has continued to use the shock devices under a decades-old legal settlement with the state of Massachusetts, but needs court approval before beginning use on each resident.School officials said in a statement they plan to challenge the government ban in court. A parents’ group also defended the practice and said it would fight the ban.“FDA made a decision based on politics, not facts, to deny this life saving, court-approved treatment,” the school said. Electric shocks and other painful or unpleasant treatments known as “aversive conditioning” were more widely accepted decades ago. But mainstream psychiatry now relies on behavioral modification, prescription drugs and other therapies that have proven more effective.“Through advancements in medical science, there are now more treatment options available to reduce or stop self-injurious or aggressive behavior,” said Dr. William Maisel, a director in the FDA’s device center, in a statement.The Rotenberg school has used shock devices carried in students’ backpacks, which were attached to their arms and legs via electrodes. School staffers could trigger a two-second shock to a patient’s skin by using a remote controller.Some patients from the Rotenberg center have compared the shocks to a bee sting or worse. The school has faced several lawsuits brought by families who said their children were traumatized by the shocks.Other parents say that the technique is the only thing that prevents violent, sometimes life-threatening behavior in their children.“We will continue to fight to keep our loved ones safe and alive and to retain access to this treatment of last resort which has allowed them to live a productive life,” said members of the Rotenberg’s parents association, in a statement. “There is simply no alternative.” The FDA, echoing psychiatric experts, said that the shock therapy can exacerbate dangerous behaviors and lead to depression, anxiety and post-traumatic stress disorder. Patients have also suffered burns and tissue damage due to the device, the agency said.Regulators said patients should instead receive treatments that focus on eliminating factors that trigger the behaviors or teaching patients coping skills to deal with them. The FDA has only banned two other products in more than 40 years of regulating medical devices -- powdered surgical gloves, which can cause allergic reactions, and fake hair implants, which caused infections and didn’t work. Typically, the FDA addresses safety issues by adding new warning labels or modifying instructions for devices. But the agency concluded that the problems with the shock devices could only be addressed by banning them.___Follow Matthew Perrone on Twitter: @AP_FDAwriter___The Associated Press receives 3717
