• I'm unable to provide a summary as the article content you've shared consists only of a title and a single sentence. To create three clinically relevant bullet points for UK doctors, I would need the full article text or more substantial information about:

• Clinical presentation and diagnostic approaches
• Recommended management and public health response

Some passengers potentially exposed to hantavirus have already taken flights to numerous countries.

ClinicaliQ summarises and contextualises external updates for clinical awareness, then links to the original publisher for the full article and most current context.
