They found several creams caused skin cancer in the specially bred mice, which had been pre-treated with ultraviolet radiation. The cancers are not melanoma, the deadliest kind of skin cancer, they stressed in their report in the Journal of Investigative Dermatology, but another type called squamous cell carcinoma. Such tumours are slow growing, highly treatable and only fatal if patients fail to have them removed. Allan Conney and colleagues at Rutgers University in New Jersey said they discovered the risk while testing a theory that caffeine could prevent skin cancer. “We sort of got into this by accident,” Conney said in a telephone interview. “We wanted a safe cream that we could put the caffeine into.”   They were testing specially bred albino mice, which are prone to develop skin cancer. The mice are pre-treated with ultraviolet radiation to simulate the effects of a human who has had heavy sun exposure in the past but then stopped — something that may be happening in the population as people realize the risks of getting a tan. Conney’s team decided to test the creams first and found that all four they tested caused tumours to grow on the mice. He said he does not know why, but suspects two ingredients — mineral oil and sodium laurel sulphate. “We’d like to understand the mechanism. What is most important is to see whether these moisturizing creams are tumorigenic in people,” Conney said. He said his lab is not equipped to do this but someone should. But he added, “I don’t think that people should be scared because this is a mouse study and we don’t know whether or not it applies to humans.”   Other experts were sceptical about the study. “This is a pretty artificial situation with the mouse skin primed by a lot of UV light to develop cancer,” Karol Sikora, Medical Director of Cancer Partners U.K. in Britain, said in a statement. Dr. Jonathan Rees, an expert in dermatology at the University of Edinburgh in Scotland, said squamous cell carcinoma was not a big health worry. “Non-melanoma skin cancer in man is very, very common and is almost 100 percent curable with an operation usually simpler than a tooth filling,” Rees said in a statement. Conney said the mouse was a commonly used model in skin cancer but said he agreed that it does not perfectly replicate human skin and human behaviour. He said his team approached Johnson & Johnson to create a cream without the suspect products and they developed one using other readily available ingredients. “They are things that are commonly used in many moisturizing creams,” he said. This cream did not cause the tumours in the mice, they said. He said Rutgers and Johnson & Johnson had patented the new cream jointly but did not know whether it would be commercially developed. A spokesman at the company was not immediately available for comment.

So far, Somalia has reported only three cases. But if the disease is unleashed, it could spread like wildfire through camps housing malnourished families who huddle under makeshift domes built from sticks and rags. Many of the 2.4 million Somalis displaced by conflict and other disasters live in such camps. Out of a total population of 15 million, around six million Somalis may not have enough to eat this year, the United Nations says, weakening their immune systems and ability to survive the pandemic. Islamist al Shabaab insurgents also hold parts of southern Somalia, making it hard for health workers to visit and impossible to do testing there. “I have witnessed wars, cholera, dysentery,” Ahmed, tall and bespectacled, told Reuters. “A doctor who fears for his life cannot save people. I have learned to forget worrying and instead help rescue people.”  A decade ago, al Shabaab seized him as he was trying to stem a cholera epidemic in territory they held. They had seen a cross inside his ambulance and - wrongly assuming it meant he was a foreign spy - arrested him and his team. A phone call from a high-level contact saved their lives, he said. Right now, Somalia only has about 25 intensive care beds, 110 quarantine beds and 100 treatment beds available, Ahmed said. More are being built. In the capital, patients at the old Italian-built maternity Martini Hospital have been moved out to make way for a new coronavirus ward. The sound of hammering echoes through its wide, tree-lined compound as construction workers rush to finish repairs. The health ministry and prime minister’s office have allocated about $11 million for coronavirus preparation, Ahmed said. Expenses are high - all medical equipment is imported and coronavirus tests are sent to Kenya for processing. The World Health Organisation (WHO) has trained 500 health workers in Somalia since January, said Dr. Mamunur Rahman Malik, the organization’s country representative. The WHO also brought in personal protective equipment to handle the first 300 or 400 cases, Malik added. Ahmed’s biggest worry is that the disease may spread very fast. Somalia has a tradition of physical greetings, and even wealthy people are reluctant to quarantine away from family. Many, like Faduma Abdikadir, simply have nowhere to isolate themselves. The 38-year-old mother is sleeping under a tree in a makeshift camp in the capital Mogadishu with her eight children, having fled fighting in the countryside. “Most of the time we use ashes and sand to wash hands. We are hungry. We beg people to buy water to drink and wash our hands,” she said.

WHY WEAR A MASK? Health experts say face coverings help prevent the spread of COVID-19. Cloth coverings cannot block the virus itself. However, they can provide some protection from droplets from breath and saliva that can carry the disease. Some people don’t realize they are infected because they have no symptoms. If they wear a mask, it limits the possibility of them unwittingly spreading the disease. HOW IS THE LOS ANGELES MASK REQUIREMENT DIFFERENT? The city of Los Angeles has the strictest requirement of any major city in the state. Mayor Eric Garcetti issued an order this week saying: “All individuals engaging in outdoor activities, except for water activities, must wear a cloth face covering.” That includes everything from walking around the block to skateboarding. The order exempts children under 2 and people with certain disabilities. Even in surrounding Los Angeles County it’s a little less stringent. Health Director Dr. Barbara Ferrer say masks aren’t needed for solitary walks or jogs. DO I HAVE TO WEAR IT IN THE CAR? Garcetti says no. But he emphasized wearing it other places when away from home and applying social distancing are foundational elements to continuing the progress Los Angeles has made against the virus. ABOUT THE VIRUS As of Friday, 1,755 people have died due to COVID-19 in Los Angeles County, which has a quarter of the state’s nearly 40 million residents but more than half the deaths. Slight decreases in hospitalizations have occurred over the last week and a half and “we are encouraged,” Ferrer said. For the most people, the virus causes mild or moderate symptoms for up to three weeks. The vast majority recover. Some older adults and people with existing health problems can experience severe illness including pneumonia and death.

Things to Know: Face covering rules vary by jurisdiction.
