# Yellow Fever Care

> ⚠️ **Ask your doctor or health care professional. This information is AI generated for education and NOT medical advice.**

Yellow fever is a serious viral disease transmitted by infected
mosquitoes, found in parts of Africa and South America. It's
preventable with a highly effective vaccine, which is required for
entry to some countries.

## Common symptoms

Fever, headache, muscle aches, nausea, and vomiting in the initial
phase; a minority of people progress to a more severe phase with
jaundice (yellowing of skin/eyes, giving the disease its name), bleeding,
and organ dysfunction.

## General self-care and prevention measures

- Get vaccinated well before travel to a yellow-fever-risk area — the
  vaccine is highly effective and, for many countries, required for
  entry (an International Certificate of Vaccination may be needed).
- Use mosquito prevention measures (repellent, protective clothing, bed
  nets) when travelling to risk areas, since the vaccine takes time to
  provide protection and isn't appropriate for everyone.
- Seek pre-travel health advice well in advance of travel to a
  yellow-fever-risk region.

## When to seek medical attention

- Fever developing during or after travel to a yellow-fever-risk area
  — mention the travel history explicitly to the clinician.
- Jaundice, bleeding, or severe symptoms after travel to a risk area —
  seek emergency care; see [[urgent-emergency-care]].
- Discuss vaccination suitability with a doctor if you have a
  condition that might make the vaccine inappropriate (it's a live
  vaccine with some contraindications).

## Common pitfalls

- **Leaving vaccination until close to travel departure** — the vaccine
  needs time (generally at least 10 days) to become fully effective,
  and some countries require proof of vaccination administered a
  minimum time before entry.
- **Assuming vaccination alone eliminates all risk** — mosquito bite
  prevention remains important even when vaccinated, both for yellow
  fever in unvaccinated situations and for other mosquito-borne
  diseases without a vaccine.
- **Not mentioning relevant travel history to a treating clinician** —
  this can delay diagnosis of a travel-related illness.
