Our advice for clinicians on the coronavirus is here.
If you are a member of the public looking for health advice, go to the NHS website. And if you are looking for the latest travel information, and advice about the government response to the outbreak, go to the gov.uk website.
Public Health England (PHE) scientists issue advice for parts of England and Wales.
In the last few days a combination of local emissions, light winds, pollution from the continent and dust blown over from the Sahara caused a spike in the UK Air Quality Index compiled by the Department for Environment, Food and Rural Affairs (Defra).
And those higher than usual levels of pollution may bring on health effects in some.
See the Public Health England (PHE) website for further details on the advice issued.
