<s>[INST] What is Q Fever? [/INST] Q Fever is a disease that can be spread to humans mainly from cattle, sheep and goats. The germ is spread in the urine, faeces and milk, but birth fluids, the foetus and the placenta are the most dangerous sources. When infected fluids dry out, the germ can remain alive in the dust for years.

People can become infected by begin splashed with infected fluids, or by breathing in infected dust.

When infected some people experience no signs, while others just feel a little 'off colour' for a few days. Most people, however, feel like they have a bad case of the 'flu, with fever and sweating, nausea, vomiting and diarrhoea for 7 to 10 days. For most people, these signs pass and there are no more problems. If you already have heart problems, you may get infection of the heart valves and severe illness as a result.

It is very rare for anybody to die of Q Fever, although some people may get other problems months or years after the first signs of disease have passed. These take the form of extreme tiredness and weakness, even after minor exercise, muscle pains, headaches, fever, and depression. This form of the disease, Post Q Fever Fatigue Syndrome, often lasts for years, and may make work, and many other aspects of normal life, impossible.

While the early disease can be very unpleasant, preventing this long lasting disease is the main aim of Q Fever vaccination. Source: Q FEVER . Link: https://www.qfever.org/faqs. Field: Infectious Disease. Disease: Fever </s>
