Q&A: The sound of your voice could help fight Covid-19

A recording of a cough, the noise of a person’s breathing or even the sound of their voice could be used to help diagnose patients with Covid-19 in the future, according to Professor Cecilia Mascolo, an expert in mobile health at data analysis at the University of Cambridge, UK.

Coronavirus lockdowns have caused air pollution to drop. Science is probing whether air pollution worsens the effects of coronavirus, with recent studies including in Italy suggesting there’s a link between polluted areas and higher fatality risk.

Q&A: China and Europe likely to see different effect of coronavirus-related air pollution drop

In March, a study revealed that between 50,000 and 100,000 deaths could be avoided this year in China if air pollution stayed at the same level as during the coronavirus lockdown. While other parts of the world have also seen improvements in air quality, the impact in Europe is likely to be less dramatic than for China, according to Dr Kristin Aunan from the Centre for International Climate Research (CICERO) in Norway, who conducted the study.

‘I don’t see any other way out’: Diagnostic testing and smartphone contact tracing to beat pandemic

What makes the Covid-19 pandemic so difficult to contain? Silent transmission by asymptomatic patients is partly responsible, but research emerging from Germany suggests the SARS-CoV-2 virus has developed a second impressive strategy for ensuring its success: the ability to establish two separate communities within a host – the first in the throat, the second in the lungs. Early colonisation of the throat is responsible for the dangerous lag between a person being infectious and the onset of symptoms.

The dangers of misinformation and neglecting linguistic minorities during a pandemic

The rapidly changing coronavirus pandemic means governments and health authorities need to act fast. But medical advice — and pleas for help — are being hindered by language barriers and misinformation online. Improving communication for vulnerable communities in particular has become a race against time.

Repurposing drugs and networks can help find outbreak treatments against the clock

A vaccine is likely to take at least a year. A new drug could be a decade away. Even with the world’s resources focused, treatments against a new disease are difficult to create from scratch. However, repurposing existing drugs for other conditions could provide a much-needed shortcut.

Studying animal coronavirus defences is opening route to human treatments

A team that has spent the last five years developing a pipeline of technologies that can churn out a remedy for almost any newly emerging virus may have treatments ready for safety trials on Covid-19 patients by the end of the year.

Q&A: We have to rethink disease detection to get ahead of the outbreak after coronavirus

We know that outbreaks like coronavirus will become more common in the future and tackling them is the Apollo programme of our time, according to Professor Marion Koopmans, head of the viroscience department at Erasmus University Medical Centre in Rotterdam, the Netherlands. 

According to Prof. Bekeredjian-Ding, an approved mRNA coronavirus vaccine would be easier and faster to produce and thus deploy worldwide than a conventional vaccine. Image credit - Unsplash/Liliya Lisa

Five things you need to know about: mRNA vaccines

The race for a vaccine against the novel coronavirus, or SARS-CoV-2, is on, with 54 different vaccines under development, two of which are already being tested in humans, according to the World Health Organization. And among the different candidates is a new player on the scene – mRNA vaccines.

Covid-19: How unprecedented data sharing has led to faster-than-ever outbreak research

Advances in gene sequencing have allowed scientists to trace and monitor the COVID-19 pandemic faster than any previous outbreak. However, gaps in our knowledge of how coronaviruses work has made it difficult to understand what makes the new coronavirus special.

Covid-19: Social distancing will help health authorities deal with coronavirus, says epidemiologist

Social distancing policies, such as cancelling high-density gatherings, discouraging handshakes and asking people to increase their distance from each other will delay a coronavirus pandemic and help health authorities plan resources, according to epidemiologist Dr Vittoria Colizza who is modelling the spread of Covid-19 and the effectiveness of interventions.
