The World Health Organization updated its guidelines on mask-wearing Tuesday, recommending that anyone over the age of 12 wear a mask indoor and outdoor and inside your home if it's ventilated poorly.The updated guidelines come as COVID-19 cases continue to sore in America. On Wednesday, 180,083 new cases were reported, according to data from Johns Hopkins University.According to the guidelines, in areas where COVID is spreading, WHO recommends that anyone over the age of 12 wear masks in shops, shared workplaces, and schools if they can't maintain a distance of more than 3-feet between others.They also recommend masks be worn when people visit your home if there's not adequate ventilation, or you can't be more than 3-feet or more from each other.The WHO said on top of wearing a mask, other precautions such as washing hands, avoiding touching your face, having adequate ventilation if indoors, testing, contact tracing, quarantine, and isolation should also be taken."Together, these measures are critical to prevent human-to-human transmission of COVID-19," WHO said.In areas of COVID-19 spread, the organization said healthcare workers should take part in "universal masking" in health care facilities, meaning they should wear an N95 respirator mask throughout their entire shift, including when caring for other patients.The advice applied to visitors, outpatients, and common areas such as cafeterias and staff rooms, but added administrative staff does not need to wear a mask if they are not exposed to patients.The organization also recommended that people who do vigorous physical activity should not wear masks, citing some associated risks, particularly asthma.For children, the WHO recommends children up to 5-years-old should not wear masks for source control. They added that children between the ages of 6 to 11-years-old should only wear masks if "a risk-based approach is applied.""Factors to be considered in the risk-based approach include intensity of COVID-19 transmission, child’s capacity to comply with the appropriate use of masks and availability of appropriate adult supervision, local social and cultural environment, and specific settings such as households with elderly relatives, or schools," the organization added in its guidelines. 2285

The wrongful death lawsuit filed by the family of Rebecca Zahau focused Thursday on the thoroughness of the investigation, with the lead Sheriff's detective on the case taking the stand. Zahau's death was ruled a suicide by four different investigative agencies but the Zahau family believes Rebecca was murdered by her boyfriend's brother, Adam Shacknai. The questioning by David Elsberg, attorney for Adam Shacknai, was aimed at showing investigators left no stone unturned. Elsberg's initial focus was on dispelling the scream that a neighbor reported may have come from the Coronado mansion around the time of Rebecca's death.  As Adam Shacknai's attorney pointed at areas of an overhead projection screen of the Coronado mansion, Detective Tsuida said the reported scream actually came from an area northwest of the property, toward the beach, and not from the balcony area where Rebecca Zahau was found dead. The attorney also showed a series of photos of footprints on the balcony, including bare prints that would support Rebecca standing on the balcony and near the balcony's edge. The questioning by Elsberg went on to the collection of potential DNA evidence and the intricate detail work involved.  Detective Tsuida testified that none of Adam Shacknai's DNA was found on the rope or knife, or several other items that might suggest he had anything to do with her death. 1480

The Senate on Wednesday will hold a hearing regarding the safety of vaccines, which will feature appearances by Surgeon General Dr. Jerome Adams and National Institutes of Health Director Dr. Francis Collins.The hearing, hosted by the Senate HELP Committee, will discuss the role of vaccines in preventing infectious disease outbreaks and protecting public health.Wednesday's hearing will also include information on a potential COVID-19 vaccine.Top U.S. health experts like Dr. Anthony Fauci say they are cautiously optimistic that there will be enough evidence to grant Emergency Use Authorization to top vaccine candidates by the end of 2020. However, recent polls indicate that some Americans remain skeptical about vaccines.A recent CBS News poll indicates that just 21% of American voters would receive a COVID-19 if one were made available at no cost. That's down from about 30% earlier this year. Two-thirds of those polled say they feel a vaccine would be "rushed" if a vaccine were made available this year.Fauci has said that if a potential vaccine is 75% effective against the virus, it still may not be effective in promoting inoculation levels necessary for "herd immunity" in the U.S. due to Americans' ongoing skepticism about vaccines.Nine vaccine makers banded together to sign a pledge on Tuesday to say that they will not seek Emergency Use Authorization for their vaccine candidates until scientific methods prove they are safe for widespread use. 1476
