A prestigious scientific panel told the White House Wednesday night that research shows coronavirus can be spread not just by sneezes or coughs, but also just by talking, or possibly even just breathing.

Fineberg told CNN that he will wear start wearing a mask when he goes to the grocery store.

"I'm not going to wear a surgical mask, because clinicians need those," said Fineberg, former dean of the Harvard School of Public Health. "But I have a nice western-style bandana I might wear. Or I have a balaclava. I have some pretty nice options."

• Authorities advise people to stay 1-2 metres apart, but researchers found that a bus passenger infected fellow travellers sitting 4.5 metres away
• The scientists behind the research said their investigation also highlighted the importance of wearing face masks because of the length of time it can linger

At the peak of the Chinese Spring Festival, the outbreak of the newly discovered coronavirus (2019-nCoV) epidemic threatened millions, with the World Health Organization, Centers for Disease Control, and numerous other international health agencies issuing official warnings.

In response to the deadly outbreak, the Chinese National Health Commission held a conference on January 22, 2020, to assess the public health crisis posed by this new virus.

Intellectual Quotient (IQ) is an imperfect predictor of many outcomes, such as academic performance and lifetime earning potential. But researchers continue to find a correlation between air quality and children’s performance on IQ tests.

The accuracy of IQ test scores as direct indicators of future academic and financial success is controversial. Indeed, IQ tests vary in competency and don’t always accurately portray the intelligence of an individual. However, many experts still find it be a valuable measurement tool.

Results chime with earlier review indicating almost every cell in the body may be affected by dirty air.

The number of health problems linked to air pollution could be far higher than previously thought, according to research suggesting hospital admissions for conditions ranging from heart failure to urinary tract infections increase as air becomes dirtier.

Air quality in Hanoi has deteriorated over the last three days and is unlikely to get better in the coming days, experts say.

The capital's Air Quality Index (AQI) was recorded at 136 on Tuesday evening by 11 air monitoring stations scattered throughout the city.

Areas with worst air quality had 27% increase in bipolar disorder analysis found.

People who grow up in areas with poor air quality are more likely to develop depression and bipolar disorder in later life, a new study has suggested.

Analysis of health data from millions of patients found a “significant link” between mental health disorders and exposure to air pollution, especially in childhood.

The lung development of children could be stunted by the release of microplastics from car tyres, according to an investigation.

Toxic particles emitted from all vehicles including exhaust fumes, metallised rubber and brake dust, are contributing to poor air quality in cities, a study for Channel 4's Dispatches has discovered.

The findings came from an experiment conducted by the programme and scientists from King's College London (KCL).

With so many different air “purifiers” available for a vast range of prices, it may be difficult to decipher what is worthwhile and what is, well, worthless. It can be tempting to settle for an inexpensive air purifier, especially when it is promoted with jargon and promises.
