Urgent warning for Australians to get vaccinated against mysterious ‘Q fever’ as cases of the rare and potentially deadly bacterial disease double

  • Queensland Wide Bay Region residents warned to vaccinate against Q fever
  • The bacterial disease is spread by animal particles and survives in dirt and dust 
  • Q fever can cause a range of symptoms with 20 per cent suffering chronically 
  • People in regional areas should wear a mask when gardening or around animals

A disease that is spread from animal particles to people has doubled its usual transmission with people urged to vaccinate and wear a mask while mowing.

Queensland Health has encouraged residents in the Wide Bay Region north of Brisbane to get vaccinated against Q fever.

The rare bacterial disease causes fever, chills, ‘drenching’ sweat, severe headaches that are often most painful behind the eyes, muscle pain, weakness, fatigue and significant weight loss.

Wide Bay Region residents have been warned to vaccinate against Q fever as confirmed cases are higher than any time in the past five years

Authorities have confirmed 11 cases of Q fever this year, double the average transmission for this time period in the last five years. 

Wide Bay Health and Hospital Service spokesman Chris McLoughlin said the disease is carried by several animals including kangaroos, cattle, sheep and goats.

‘People become infected by breathing in droplets of the bacteria or dust contaminated by birth fluids, faeces, or urine from infected animals,’ he told Courier Mail

It’s believed the disease is spreading at a quicker pace because more people are moving to live outside of major cities.

Abattoir and butcher workers are at the highest risk of infection but people with pets or that live in areas close to wildlife should also consider vaccination.

Residents are advised to wear a P2 face mask when doing activities that could stir disease particles, like mowing and gardening.

‘It can persist in the general environment in dust and soil, which can lead to infection and disease,’ public health physician Dr Josette Chor said said. 

‘Dry and windy conditions can increase the risk of transmission to humans.’ 

Person to person transmission of Q fever is rare but it is possible pets can carry the disease.

Q fever can be treated with a course of antibiotics but up to 20 per cent of people can suffer from chronic symptoms up to 12 months after infection.

Q FEVER QUICK FACTS

WHAT IS Q FEVER?

Q fever is a disease caused by the bacterium Coxiella burnetii. 

It is spread to humans from cattle, sheep and goats and a range of other domestic and wild animals. 

Even people who do not have contact with animals may be infected.

WHAT ARE THE SYMPTOMS?

Many infected people have no or few symptoms. 

People who do become sick often have a severe flu-like illness. 

Symptoms begin about 2-3 weeks after coming into contact with the bacteria and typically include:

  • high fevers and chills
  • severe ‘drenching’ sweats 
  • severe headaches, often behind the eyes
  • muscle and joint pains
  • extreme fatigue (tiredness)

Patients may also develop hepatitis (inflammation of the liver) or pneumonia (infection of the lungs). 

Without treatment, symptoms can last from 2-6 weeks.  

About 10% of patients who are sick with acute Q fever go on to suffer from a chronic-fatigue-like illness which can be very debilitating for years.

HOW IS IT SPREAD?

People usually get infected by breathing in the Q fever bacteria that is in the air or dust. 

Cattle, sheep and goats are the main sources of infection, however a wide range of animals including domestic and feral dogs and cats, feral pigs, horses, rabbits, rodents, foxes, and Australian native wildlife can also spread the bacteria to humans. Infected animals often have no symptoms. 

The bacteria can be found in the placenta and birth fluids (in very high numbers), urine, faeces, blood or milk of animals who are infected with or carry the bacteria. 

The bacteria can survive in the soil and dust for many years and be spread over several kilometres by the wind.

You can get infected with Q fever by:

  • breathing in the bacteria that is in the air or dust
  • direct contact with infected animal tissue or fluids on broken skin (e.g. cuts or needlestick injuries when working with infected animals)
  • drinking unpasteurised milk from infected cows, sheep and goats.

WHO IS AT RISK? 

Workers in the following occupations are at high risk of Q fever:

  • abattoir and meat workers
  • livestock and dairy farmers and farm workers
  • shearers, wool classers/sorters, pelt and hide processors
  • stockyard/feedlot workers and transporters of animals, animal products and waste
  • veterinarians, veterinary nurses/assistants/students and others working with veterinary specimens
  • wildlife workers working with high-risk animals (including Australian native wildlife)
  • agriculture college staff and students (working with high-risk animals)
  • laboratory workers (working with the bacteria or with high-risk veterinary specimens)
  • animal shooters/hunters
  • dog/cat breeders, and anyone regularly exposed to animals who are due to give birth
  • people whose work involves regular mowing in areas frequented by livestock or wild animals (e.g. council employees, golf course workers or staff of mowing businesses in regional and rural areas).

Other people at increased risk of Q fever include:

  • family members of those in high-risk occupations (from contaminated clothes, boots or equipment)
  • people living on or near a high-risk industry (e.g. neighbouring livestock farms, stockyards housing cattle/sheep/goats, meatworks, land being fertilised with untreated animal manure)
  • visitors to at-risk environments (e.g. farms, abattoirs, animal saleyards and agricultural shows)
  • horticulturists or gardeners in environments where dust, potentially contaminated by animal urine, faeces or birth products, is aerosolised (e.g. lawn mowing).

HOW IS IT PREVENTED?

  • Vaccinate against the disease using Q-VAX
  • wash hands and arms thoroughly in soapy water after any contact with animals
  • wear a properly fitted P2 mask and gloves and cover wounds with waterproof dressings when handling or disposing of animal products
  • wear a properly fitted P2 mask when mowing or gardening in areas where there are livestock or native animals
  • wash animal urine, faeces, blood and other body fluids from equipment and surfaces where possible
  • remove and wash dirty clothing, coveralls and boots worn during high-risk activities in outdoor wash areas.
