Clinical signs of brucellosis in cattle

Brucellosis is an infection that can spread among cattle and may pass to people through contact with birth fluids, placentas, aborted tissues, milk, or other contaminated material. In a herd, repeated reproductive problems may raise concern, but these signs can have other causes. People exposed to infected cattle may develop fever, tiredness, joint pain, muscle aches, or night sweats; the condition presents with these symptoms rather than the symptoms proving its cause.

Do not handle an aborted fetus, placenta, or soiled bedding with bare hands. Separate potentially affected animals according to veterinary advice, keep records of reproductive events, and contact a veterinarian or animal-health authority for testing and herd control. Anyone who handled these materials should wash thoroughly and tell a clinician about the animal contact. A blood test may help assess a person with compatible symptoms; treatment decisions belong to a clinician.

Seek medical advice promptly after relevant cattle exposure if fever, marked weakness, joint pain, muscle aches, or night sweats develop, especially when symptoms continue or return. Urgent care is appropriate for confusion, breathing difficulty, fainting, severe dehydration, or rapidly worsening illness. Avoid unpasteurised milk and do not start antibiotic treatment without professional guidance.

Tell the clinician which animals or materials you handled, whether protective equipment was used, when the exposure occurred, and whether unpasteurised dairy products were consumed. Ask whether testing is appropriate, what symptoms should trigger review, and how prescribed treatment should be taken.
