A virology expert answers key questions on COVID-19

  1. Mutations in viruses — including the coronavirus causing the COVID-19 pandemic — are neither new nor unexpected. Bollinger explains: All RNA viruses mutate over time, some more than others. For example, flu viruses change often, which is why doctors recommend that you get a new flu vaccine every year
  2. With the World Health Organization (WHO) saying the world should do more to prepare for a potential coronavirus pandemic, it's important to remain realistic but alert to the risk posed by COVID-19. In the UK, our actions as individuals will go a long way in preventing, detecting and isolating potential cases of this new virus
  3. The legal group goes on to explain that 'covid-19' has not been subjected to the 130 year established legal, medical, and scientific procedure that recognises if it is actually a disease or virus or not, which is known as the Koch Postulates. This involves purifying and isolating the 'disease' or 'virus' and proving that it actually causes the illness that it is claimed that it does

By that point, the SARS-CoV-2 virus, which causes Covid-19, had been identified using electron microscopy; there was no need to use metagenomic sequencing to find a mystery agent Here are 10 ways you can help others during the pandemic. 1) Mobilise for morale: join a mutual aid group.
