01 · Know
What is Q fever?
Q fever is a bacterial infection caused by Coxiella burnetii, most often spread to humans from farm animals such as cattle, sheep, and goats, particularly through contact with birth fluids, unpasteurised milk, or contaminated dust.
Many infections cause mild, flu-like symptoms or none at all, but some people develop a more significant illness with fever, severe headache, and fatigue. Rarely, it can become a long-term (chronic) infection affecting the heart or other organs.

03 · Act
When to see a doctor
- 1You develop a fever, severe headache, and fatigue, particularly after contact with farm animals
- 2Symptoms don't improve after a week or worsen over time
- 3You have a pre-existing heart valve problem and are concerned about exposure
- 4You develop chest pain, breathlessness, or other new symptoms during recovery
- 5You work with livestock and want advice on reducing your risk
04 · Prevent & manage
Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Rest and stay hydrated.Supporting your body while it fights the infection is an important part of recovery.
- 2Take prescribed antibiotics fully.If antibiotics are prescribed, completing the full course helps clear the infection and reduce the risk of it becoming chronic.
- 3Practise good hygiene around livestock.Wearing protective equipment and washing hands thoroughly after contact with animals, especially during birthing, reduces risk.
- 4Avoid unpasteurised dairy products.These can be a source of Q fever infection.
- 5Attend follow-up if you have heart valve problems.People with pre-existing heart valve disease may need closer monitoring after Q fever infection.

BarnMD Bottom Line
Most Q fever infections are mild or cause flu-like symptoms that resolve with rest and, if needed, antibiotics.
People who work closely with livestock can reduce their risk through good hygiene practices and appropriate protective equipment.
