South Africa has reported the most coronavirus cases in sub-Saharan Africa, and public health experts are worried that the virus could overwhelm the health system if infection rates rise steeply. President Cyril Ramaphosa has been praised for ordering some of the toughest measures on the continent to try to halt the spread of the virus, including a 21-day lockdown from midnight on Thursday, deploying the army to support police and ordering underground mines to suspend operations. Public Works Minister Patricia de Lille told a news conference that her ministry had identified more than 16,000 beds in potential quarantine facilities, including government buildings, hotels, holiday properties and hospitals. De Lille's spokeswoman and a Health Ministry spokesman were not able to say who would be placed in the quarantine sites. Health Minister Zweli Mkhize said in an interview with state broadcaster SABC that it was still "early days" in terms of the number of infections. "We are expecting that there is still going to be quite an increase in the number of cases, and we are also expecting that a lot of work needs to be done by South Africans to contain this infection," Mkhize said. Businesses of all sizes are bracing for a big impact from the lockdown, with Airlink becoming the latest local airline to suspend flights from midnight on Thursday and state power utility Eskom applying for its critical staff to be exempt so that electricity supplies can continue uninterrupted. South African National Parks said it would close all its tourism facilities to the public from Wednesday. Mining Minister Gwede Mantashe said production of gold, chrome, manganese and other minerals would be scaled down but that the processing of platinum group metals would continue. The South African Reserve Bank (SARB) launched a bond-buying programme, giving into public and political pressure to intervene more directly in providing stimulus. Government bonds including the 2030 issue rallied on the SARB intervention.

The story does include a discussion of price, reporting that a fluoride varnish treatment can cost $23 to $55, while a filling can cost $86 to $606. That's enough to be rated Satisfactory. However, the story also should have stated that those numbers aren't a head-to-head comparison, since the varnish treatment must be repeated many times over many yearswhich would add up. In fact,a cost-effectiveness analysis done by one of the quoted experts concluded the "Caries Management System" he advocates costs almost $1,800 for every cavity or lost tooth prevented. While the story includes links to some studies that report specific results, the only number reported in the story is a reduction in adult tooth fillings of 30 to 50 percent. But without any absolute numbers, this number isn't useful. Is it a cavity a year? A cavity a decade? The story refers to people at "high risk" for cavities, but does not define what that term means. Without some anchoring in absolute numbers, all readers are left with is a vague sense that preventive treatment is "better" for some people, without pinning down how much better or for whom. Fluoride for dental health has been extensively studied for decades and is considered safe, so we'll file this rating as not applicable to the story. But, as some dentists might point out, there is an argument to be made for discussing one knownthough minorrisk: Some people living in areas with naturally high levels of fluoride in their water may experience tooth discoloration or other issues if they are given additional fluoride treatment. The story portrays the evidence for fluoridetreatments as clear and convincing, when there are actually just a few studies, and a lot of expert opinion. That's not to say the experts quoted in the story are wrong, but the story elevates beliefs to the level of evidence-based conclusions. Cavities in adults can cause serious health problems if left untreated, and any new effective treatment or trends in this area is worthy of press coverage. However, the studiesdiscussedin the story focused on a relatively small group of people with unusually high risk of tooth decayand so these results may not apply to the adult population at large, which this piece implies. The story quotes a number of sources discussing this trend in dentistry, instead of just relying on one dentist. But the piece would be more balanced had it included at least one source pointing out that some of the techniques advocated in the story could be overkill or wasteful for many people who are at just average risk for tooth decay. As the piece was written, all the sources are very rosy about more aggressive preventive dental care. We also found via an internet search that sourceJohn Featherstonehas accepted consultation fees from dental companies that make products for these purposes. However, since he wasn't specifically endorsing one of these productsin this story,we'llgive this a pass. The story does not quantify the benefits of these new preventive treatments, or similar approaches, so it fails to give readers a useful comparison with standard dental care or advice for most adultssuch asfluoride toothpastes, community water fluoridation, flossing, and mouthwashes. It is clear that the treatments mentioned in the story are widely available, and we were pleased to see the story went a step further and let us know how insurance impacts availability. The story reports that the concepts are not new, and that fluoride varnishes have normally been the purview of pediatric dentistry, but are now catching on among adult dentists. However, it never really explains why practice would be changing nowdid research spur this change? There is a reference to "more effective preventive techniques," but it's not clear what that means, and how a reader might act on that. This piece doesn't appear to rely on a news release; the reporter interviewed a number of experts and referred to several publications.

The WHO's Kate O'Brien put the blame on weak health systems and misinformation about vaccines, and called on social media outlets and communities to make sure information about preventing the highly contagious disease was accurate. "We are backsliding, we are on the wrong track," O'Brien, director of WHO's department of immunization, vaccines and biologicals, told a news briefing. "We have a worrying trend that all regions are experiencing an increase in measles except for the region of the Americas, which has seen a small decline." Nearly three times as many cases were reported from January to July this year than in the same period in 2018, the WHO said. Nearly 365,000 cases have been reported globally this year, the highest figure since 2006, it said, noting that they represent only a fraction of the 6.7 million suspected cases. Measles caused an estimated 109,000 deaths in 2017, its most recent figures show. The biggest outbreaks are raging in the Democratic Republic of Congo (155,460 cases), Madagascar (127,454) and Ukraine (54,246), it said. Europe has also lost ground, with four countries stripped of their "measles-free" status in 2018 - Albania, Czech Republic, Greece and Britain, it said. The WHO figures did not include a specific breakdown of numbers for the Americas region. The United States has recorded 1,215 measles cases across 30 states in its worst outbreak since 1992, federal health officials said on Monday. Health experts say the virus has spread among school-age children whose parents declined to give them the measles-mumps-rubella vaccine, which confers immunity to the disease. Trust in vaccines - among the world's most effective and widely used medical products - is highest in poorer countries but weaker in wealthier ones where scepticism has allowed outbreaks of diseases such as measles to persist, a global study found in June. "We do see misinformation as an increasing threat," O'Brien said. "We are calling on social media providers, communities, leaders, people who speak out, to be sure you are communicating accurate, valid, scientifically credible information." In the 53 countries of Europe, 90,000 measles cases were recorded in the first half of this year, already more than that for all of 2018, said Siddhartha Datta, from the WHO's regional office for Europe. Ukraine, which accounts for more than half of the cases, is implementing a robust response, he said. "The ministry of health is doing targeted immunization campaigns ... They are also doing school-based vaccination, high-risk vaccination of military recruits and health care workers." (This story was refiled to fix typo in first paragraph.)
