Modelling study estimates impact of physical distancing measures on progression of COVID-19 epidemic in Wuhan

New modelling research, published in The Lancet Public Health journal, suggests that school and workplace closures in Wuhan, China have reduced the number of COVID-19 cases and substantially delayed the epidemic peak — giving the health system the time and opportunity to expand and respond.advertisement Using mathematical modelling to simulate the impact of either extending or relaxing […]

Misinformation on vaccines readily available online

Parents researching childhood vaccinations online are likely to encounter significant levels of negative information, researchers at the University of Otago, Wellington, have found.advertisement Lead researcher Dr Lucy Elkin says negative information about vaccines remains readily available on Google, Facebook and YouTube, despite attempts by the internet platforms to better control access to misinformation through algorithm […]
