A new study by researchers at Queen Mary University of London, University of Oxford, Institute for Advanced Studies, Vienna, and the Medical University of Graz, has found that lateral flow tests detect Covid-19 with similar accuracy to laboratory-based PCR tests, providing they are used at the onset of infection and soon after symptoms start.
Lateral flow tests are cheaper and produce a result in just 30 minutes - much faster than the time it takes to receive a PCR test result, which can take 1-3 days. The finding could be pivotal to national strategies looking to tackle the next phase of the pandemic, especially as timely and rapid testing becomes even more important once the current restrictions lift in England.

E-cigarettes are more effective than nicotine replacement treatments in achieving long term smoking reduction and cessation, according to the results of a clinical trial by Queen Mary University of London.
Some 80 per cent of smokers receiving intensive treatment continue to smoke after a year. Smokers could benefit from approaches that reduce the harm from smoking without ceasing nicotine use, with an option to stop nicotine later on. Nicotine replacement treatments (NRT), such as nicotine patches, chewing gum, nasal/mouth spray and inhalators, have been licenced to do this for over 30 years. They work, especially if behavioural support is also provided, but the results are modest.
