Flu cases are climbing across Hawaii, and health officials are urging shots and basic precautions — bad news for anyone heading into crowded indoor spaces, but the fixes are simple.

• One in five respiratory tests in the state came back positive for flu last week, up from the week before.
• Health officials want everyone 6 months and older to get a yearly flu shot.
• The updated COVID shot is recommended for higher-risk groups: babies, people 65 and older, and anyone 2 to 64 with health risks.
• Anyone who feels sick should stay home, cover their cough, and wear a mask if they have to be around others — especially healthcare workers.
• Flu-like symptoms are worth a test, since treatment works better when started early.

Outlook: Respiratory illness is likely to keep rising through the season, so expect more pressure on clinics in the coming weeks.
