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 Trump administration plans to raise pending tariffs on 0 billion in Chinese goods to 25% from 10%, a source familiar with discussions confirmed to CNN.The news was first reported by Bloomberg.The move, which is not finalized and could change, according to the source, comes as the United States and China remain locked in a trade war. Talks between US and Chinese officials have done little to ease tensions.The United States has already imposed 25% tariffs on Chinese goods worth billion. China immediately responded with its own tariffs on US goods worth billion.A second round of tariffs on products worth billion could take effect as soon as this week.US Trade Representative Robert Lighthizer earlier this month ratcheted up tensions when he released a list of thousands of additional Chinese exports worth 0 billion that could face 10% tariffs after a public comment period. It included fruit and vegetables, handbags, refrigerators, rain jackets and baseball gloves.Those tariffs, which might now be steeper, could go into effect as soon as September. 1108

The World Health Organization is preparing for the "worst case scenario" as it continues to respond to the Ebola outbreak in the Democratic Republic of Congo.Peter Salama, deputy director-general of emergency preparedness and response at the WHO, said in Geneva, Switzerland, on Friday that it's "going to be tough and it's going to be costly to stamp out this outbreak."As of Wednesday, 32 people are suspected to have been infected with Ebola viral disease, including three health care workers. Eighteen of those have died, including one of the health care workers.Of the suspected cases, two have been confirmed as Ebola using laboratory tests, and 10 samples are awaiting results."The number of suspected, probable and confirmed cases is significant, so we are very concerned, and we are planning for all scenarios, including the worst-case scenario," Salama said.Ebola virus disease, which most commonly affects people and nonhuman primates such as monkeys, gorillas and chimpanzees, is caused by one of five Ebola viruses. On average, about 50% of people who become ill with Ebola die.The disease is endemic to the Democratic Republic of Congo, and this is the nation's ninth outbreak since the discovery of the virus in the country in 1976.The latest outbreak is occurring in the Bikoro health zone, 400 kilometers (about 250 miles) from Mbandaka, the capital of Equateur province.Bikoro health zone has a population of about 163,000, with three hospitals and 19 health centers, most with limited functionality, according to WHO.Given the remote location of the outbreak, Salama said, response efforts will be extremely challenging. "It is a dire scene in terms of infrastructure," he said."To give you a sense, we are talking about an area that is 280 kilometers even from the provincial capital of Equateur," he said.The WHO is working with authorities in Congo and is in discussions with the World Food Programme to arrange airlifting supplies to the affected areas. UNICEF is also making doctors available as well as sanitation and hygiene specialists to help contain the outbreak.The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission, either through direct contact with bodily fluids such as blood or secretions or contact with materials that are contaminated with these liquids.Personal protective equipment has been sent to the affected region, and the WHO is planning to have mobile laboratories running by the weekend, after receiving approval from the country's Ministry of Health.Initial control efforts are focusing on tools such as surveillance and monitoring, safe burials and case management.Vaccines along with doctors and epidemiologists are on standby in case they are needed, according to the UN.If they are needed, "WHO is in discussions with the government and, if pertinent, will seek approval from the national regulatory authority and the Ethics Review committee to use vaccines against Ebola as part of the response," spokesman Tarik Jasarevik said.The current vaccine against Ebola is experimental and not a licensed product. Salama pointed out that its use also comes with many challenges, as the vaccine needs to be stored long-term at temperatures between minus 60 to minus 80 degrees Celsius (minus 76 to minus 112 Fahrenheit)."This is not a simple logistical effort; it's not like doing a polio campaign with oral polio vaccines, where we get it immediately out to the field. This is a highly complex sophisticated operation in one of the most difficult terrains on Earth," Salama said.Nine neighboring countries are on high alert, Salama said, but the WHO says the current risk of disease spreading to them is low.West Africa experienced the largest recorded outbreak of Ebola over a two-year period beginning in March 2014; a total of 28,616 confirmed, probable and suspected cases were reported in Guinea, Liberia and Sierra Leone, with 11,310 deaths, according to the WHO.  3999

The US will respond to the Assad regime's alleged chemical attack against Syrian civilians, US Ambassador Nikki Haley told the United Nations as she excoriated Russia, saying its hands are "covered in the blood of Syrian children.""Chemical weapons have once again been used on Syrian men, women and children," Haley said at a special meeting of the United Nations Security Council to discuss what appeared to be a chemical attack on Douma, the last rebel-held town in Syria, on Saturday that left 49 people dead and scores injured."History will record this as the moment when the Security Council either discharged its duty or demonstrated its utter and complete failure to protect the people of Syria," Haley said. "Either way, the United States will respond."Images of gasping children struggling to breathe shocked the world and galvanized President Donald Trump, who condemned the attack as "sick" and upbraided Russian President Vladimir Putin and Iran for supporting Syrian President Bashar al-Assad.Trump threatened that there would be "a big price to pay" for the attack.On Monday, Haley made clear that Russia could "pay" as well, as tensions between Washington and Moscow were laid bare in the Security Council. Russia's ambassador accused the US of plotting against Moscow and Syria, threatening international security, stoking global tensions and operating outside the confines of international law.Haley described at length and in detail blue-skinned Syrian toddlers lying dead in their parents' arms after the suspected chemical attack and made clear that the US sees Moscow as responsible. Russia, she implied, is not even a civilized nation."The monster who was responsible for these attacks has no conscience to be shocked by pictures of dead children," Haley said, explaining that she wouldn't show photos of the victims as she had after a chemical attack in April 2017 that led to US strikes on Syria."The Russian regime, whose hands are also covered in the blood of Syrian children, cannot be shamed by pictures of its victims," she said. "We've tried that before.""Russia could stop this senseless slaughter, if it wanted," she said. "But it stands with the Assad regime and supports it without hesitation. What's the point of trying to shame such people? After all, no civilized government would have anything to do with Assad's murderous regime.""Russia's obstructionism will not continue to hold us hostage when we are confronted with an attack like this one," she added.Russia pushed back hard. "Nobody has invested you with the authority to act as gendarmes, policemen of the world ... we call on you to return to the legal fold," Ambassador Vassily Nebenzia said. Earlier, Russian Foreign Minister Sergey Lavrov had argued that there is no evidence chemical weapons were used, a claim Nebenzia echoed."The use of sarin and chlorine is not confirmed," Nebenzia echoed in the Monday meeting. He went on to say that the US, along with the UK and France, is acting "without any justifications, and without considering the consequences have engaged in a confrontational policy toward Russia and Syria."In extended, rambling remarks, Nebenzia accused the US of plotting a strike against Damascus and planting the "fake news" of the Douma attack Saturday as justification. He then veered off onto the subject of an alleged nerve agent attack on a former Russian spy in the UK, attempting to link all the events."Is it not clear to all? Syria, Russia, Salisbury," Nebenzia said, referring to the British city where the spy was poisoned.The UN's special envoy for Syria, Staffan di Mistura, noted that some states have publicly raised their suspicions that Syria was behind the attack. Other states, he said, "have strongly questioned the credibility of these allegations.""What reason more, then, for a thorough, independent investigation," he concluded, as he denounced the use of chemical weapons as "abhorrent" and called for a thorough investigation.Nongovernmental organizations on the ground had documented "hundreds of cases of civilians with symptoms consistent with exposure to chemical weapons," he said.Between August 2013 and February 2018 there have been at least 85 confirmed chemical attacks in Syria, with the Syrian government responsible for at least 50 of them, according to Human Rights Watch.Even before Nebenzia's accusations, Mistura warned about the hostilities in Syria spiraling out of control to threaten international stability. "I have reached a point in which I am expressing a concern about international security," he told the council.Telling the gathered officials that recent developments carry more danger than ever, he said that "different fault lines that are completely crossing each other and are interconnected" and escalation could "have absolutely devastating consequences that is difficult for us to even imagine.""The council cannot allow a situation of uncontrollable escalation in Syria on any front," he said.Haley and other speakers stressed that a dangerous precedent is being set."We are on the edge of a dangerous precipice," Haley said. "The great evil of chemical weapons use that once unified the world in opposition is on the verge of becoming the new normal. The international community must not let this happen." 5312

The recount effort underway in Georgia has uncovered roughly 2,600 ballots that hadn’t originally been included in the tally.State officials say county election officials in Floyd County didn’t upload in-person early votes from a memory card into a ballot scanning machine, according to the Atlanta Journal Constitution newspaper.Floyd County is located in northwest Georgia.In the uncounted votes, there were 1,643 new votes for President Donald Trump and 865 votes for President-elect Joe Biden. County officials say these ballots rectify their discrepancy between the number of people who checked-in to vote and the number of ballots counted in Floyd County.President Trump's campaign issued a statement Tuesday afternoon in response to reports of the previously unaccounted ballots."Recent revelations from Georgia's ongoing statewide recount have shown that President Trump was absolutely correct to raise concerns about widespread voting irregularities that have favored the Biden-Harris ticket," the statement reads. "The State of Georgia must not certify its results until the recount is done accurately and the results are correct."“It’s not an equipment issue. It’s a person not executing their job properly,” said Gabriel Sterling, the state’s voting system manager. “This is the kind of situation that requires a change at the top of their management side."The head of the Republican Party in Floyd County said the issue was concerning, but “doesn’t appear to be a widespread issue,” and he was glad the ballot audit revealed it.Georgia’s audit of the nearly 5 million ballots cast is set to be finalized Friday. 1632
