The New Covid Pandemic is starting
One of the impacts of the Sars-Cov-2 pandemic is the increased surveillance capacity in most countries. When we look more carefully, we see more things. This is a good thing, People are properly diagnosed, and better treatments delivered. Every pandemic leaves its mark on medicine. if we count from 1918 flu; the impact from that was the idea of PPE and distancing. The 1920s saw the start of a 40 year polio pandemic. The iron lung came about because of that, but disappeared because of the success of thr polio vaccine. But the lasting legacy of polio was Intensive Care Medicine, invented in Denmark as a response. And now we can't think of medicine without it Another benefit of polio; the FDA. Prior to Salk's polio vaccine, there was no FDA. There were no clinical trials. Salk developed a polio vaccine, which reduced Eisenhower to tears. His approach was to use inactivated polio vaccine. Key was using formaldehyde to kill the virus. Contracts to make millions of batches went to 3 companies. One of these companies didn't know how to make formaldehyde, with the result 200,000 kids were infected. The FDA was formed as a result, to provide regulatory oversight to the companies making medicines. End of the 50; China or Mao flu; 20 years earlier, Australia developed the first flu vaccine (remarkable, as the flu virus was only discovered in the 1930s). The vaccine had only limited utlity unless you knew the serotype of the virus in circulation. In 1957, a lab in Singapore, with Walter Reed in US, for the first time identified the serotype of a circulating flu virus, allowing vaccine to be manufactured in response. This stopped the 1968 Hong Kong flue from becoming a pandemic, thanks to production of an The work really initiated the whole area of molecular diagnostics, and transformed the role of the path lab. We know from improved diagnostics that the measles vaccine is not as effective as previously though. It does not prevent infections. In a population of vaccinated kids, PCR will show the virus circulating. But the burden is reduced such that the kids won't develop measles. Time tell what the lasting legacy is from COVID. Initially I thought it might be increased diagnostics capacity; before covid, not all countries could carry out PCR at large scale.. During COVID, there were massive investments into labs, which in theory should have left a skilled workforce, setting the scene for better cancer diagnostics. But that capacity was quickly stood down. -

Trump Moves Forward with Tariffs on Canada and Mexico, Citing Trade Deficit and Border Issue
A lot of US refineries are only set up to process heavier crude that comes from Canada and Venezuela, You can change a refinery to process different oil if you have several years and billions of dollars to do so. US oil is mostly of the lighter grade, some of that is refined in the US for their own use but they rely on our heavy crude as it's bought at a discount because it requires more processing A lot goes for export.Some of it back to Canada The oil and gas industry in North America is setup to transfer product back and forth Heavy crude is exported from Vancouver to Washington state and gasoline is sent back to the lower mainland The oil business lives on exporting and importing, Even Saudi imports refined products -

FAA’s Diversity Policies Under Fire After Deadly Air Collision
Apologies MicroB. Nothing I’ve written was meant to hit that nerve. My answers have all been looking at front line air traffic staff as that’s what many AN posters and the media have been blaming for this horrendous crash. My general points about ‘best person for the job’ still apply to cleaners and many other non-front line jobs. And, of course, a Down’s person, or someone with another special need, is totally capable of doing so many important roles in any workplace, and indeed can be the best person for that role. But, of course, not every role. I have my doubts about some other AN posters of course, their needs are too far along that ‘special’ spectrum. 😆 Again, apologies, for causing this upset.
