How to treat sandfly bites in Nha Trang and when should you seek medical care?

If you notice the bite straight away, use a strong alcohol-based antiseptic on the spot to help limit the local reaction. Prompt treatment is especially useful for sandfly bites, which can otherwise itch and stay irritated for around two weeks or longer.

Sandfly bites may go unnoticed at first: itching can start in the evening, the next morning, or when salt water touches the skin. Check your skin after the beach and treat suspected bites without scratching them.

For marked swelling, itching, or an allergic-type reaction, a topical ointment plus an antihistamine may help. If symptoms worsen, swelling spreads, or concerning symptoms appear, contact your travel insurer and go to a hospital.
