Fever Q
"""Q fever: what is it and what causes it?

A contagious illness known as Q fever (Query fever) can be contracted by humans from animals. Coxiella burnetii is the bacterium responsible for Q fever. This microorganism can live in dirt or dust for months or perhaps years. The Q fever bacteria can be found in tissues involved in childbirth, including the uterus, placenta, and birth fluids, in animals including cattle, sheep, and goats. The microorganism is also released in milk and feces from infected animals. Infected dusts and aerosols produced by animals or animal products are inhaled by humans to become infected. Numerous infections have no symptoms (asymptomatic). Common symptoms include a high temperature, chills, and excessive perspiration, mimicking a severe attack of the flu. People can occasionally suffer liver and cardiac issues. Some people may acquire a significant chronic Q fever that, if untreated, can be fatal.

How is the Q fever spread?

Typically, the Q fever bacterium is inhaled by a person to cause Q fever. It spreads quickly. An infection can begin with as little as 10 Q fever bacteria. Q fever can also be contracted by skin contact and milk consumption, however the majority of illnesses are transmitted through the air. Rarely, if ever, does transmission happen from person to person.

What signs or symptoms indicate Q fever?

People may be unaware they have Q fever or think it is a minor case of the flu. Without performing laboratory testing, it is frequently impossible to determine if the sickness is Q fever. Numerous employees at the same workplace may occasionally become suddenly ill with Q fever. Common indications and symptoms mirror a severe flu infection: quick onset of weariness, muscle ache, and a high temperature chills and a headache with perspiration widespread apprehension of being ill and appetite loss ineffective cough slim down abdominal pain a chest ache Some people experience a mild, dry cough as a result of pneumonitis, a lung inflammation. Most symptoms go away within 7 to 10 days. However, affected individuals may experience generalized illness and appetite loss for several weeks. A small minority of individuals experience liver disease, such as hepatitis, as well as jaundice, which is characterized by a yellowing of the skin and a darkening of the urine. Endocarditis, an inflammation of the lining of the heart cavity, is one of the described rare clinical disorders. The condition may manifest differently depending on where you live. Although the reason is unclear, animal studies indicate that various strains might play a role.

What Q fever tests are available?

Antibodies that circulate in the blood are measured during laboratory tests for Q fever. The body manufactures antibodies as a defensive mechanism against infectious illnesses. Patients with these antibodies appearing in their blood after a period of unexplained feverish sickness can be diagnosed with Q fever.

What is the Q fever treatment?

Patients with acute Q fever typically recover without the need for antibiotics. Tetracycline (doxycycline), an antibiotic, is frequently used to treat acute Q fever when necessary. Patients typically make a full recovery when treatment is initiated right away. Both hydroxychloroquine and doxycycline may be administered for several months to treat chronic Q fever. Rarely is q fever deadly. Chronic Q fever, particularly in people with pre-existing heart problems, can be lethal if left untreated.

Is Q fever a problem for the workplace?

Workers who come into touch with animals, animal products, or animal feces may be at risk for developing Q fever. Workers who have cardiac issues or immune systems that are weakened are more vulnerable. Several distinct types of animals can transmit Q fever to workers: Wild creatures farm animals, particularly cattle, sheep, and goats animals used in laboratories, particularly sheep, and family pets, particularly cats Ticks that feed on human blood hardly ever convey the Q fever bacterium to wild animals. However, farm animals, lab animals, and pets can contract Q fever directly from diseased animals or contaminated environments. Q fever poses a particular risk to pregnant animals, particularly during the time when they give birth or experience an abortion as a result of the illness. The Q fever bacterium multiplies astronomically in some tissues and fluids of pregnant animals. These consist of the uterus, also known as the womb, the placenta, which covers the developing fetus in the womb, the mammary glands, sometimes known as the udders, birth fluids, and milk. These microbes become airborne in tiny droplets of mists or aerosols and spread to workers: when animals give birth,during processing of infected tissues from slaughtered animals, at milking or during the processing of milk, or during animal surgery. Animals typically consume their placenta and other postpartum tissues after giving birth. The Q fever germs are able to survive digestion when this occurs. They pass along the animal's intestine and become discharged with the manure. This discharge allows Q fever to spread widely throughout the environment. The Q fever microbe easily becomes airborne with dust from infected animal tissues, manure, or soil. As a result, workers can become exposed to Q fever by contacting various infected materials such as dust from animals, bedding, or manure,soil near animal pens, animal hides, wool, and furs, and clothes from workers who were exposed to infected animals or materials.

What occupations are at increased risk for Q fever?

Q fever spreads easily throughout agricultural regions affecting anyone who works outdoors in contact with infected soil or dust. Airborne particles containing the Q fever microbe may be carried downwind for a considerable distance--one-half mile or more. Q fever also spreads easily within buildings from room to room. Workers in research facilities can catch Q fever even if they only visit a contaminated room or hallway once or twice. General medical staff do not normally get Q fever from infected patients. Some of the occupations at increased risk for Q fever include the following: farmers, ranchers, and farm workers in contact with cattle, sheep, and goats,stockyard workers, truck drivers, personnel who service the trucks, and visitors to animal auctions, meat packers, rendering plant workers, hide and wool handlers, hunters and trappers, laboratory animal researchers and support staff, workers who care for pets and livestock--veterinary personnel, pet shop workers and zoo attendants, and certain groups of medical and health care personnel who have contact with blood, sputum or tissue from infected patients.

How can we prevent Q fever in the workplace?

For most effective prevention, the Q fever microbe should be eliminated from animals. Eradications programs, however, are not yet available because Q fever spreads so effectively among animals. Workers who have even remote contact with animals, animal products, and animal waste should be informed about the disease, its characteristics, and the nature of the risk. Workers who start jobs with increased risk of Q fever should be offered blood tests to determine if they have resistance to Q fever. The possibility of Q fever should be investigated in high risk workers who develop an unexplained feverish illness, especially if lung infections develop. Q fever is a reportable disease in most Canadian jurisdictions. The risk of infection from the workplace can be reduced by: vaccination of workers where available,personal precautions, and workplace hygiene. Vaccination of workers While there is a vaccine available, it is not readily available in Canada. The use of this vaccine should be limited to those at high risk of exposure whose blood tests for resistance to Q fever are negative. Before vaccination, workers must have tests to determine if they are already immune to Q fever, otherwise they may have a severe reaction. If not already immune, the person must also have a test to determine if they are allergic to components in the vaccine. Personal precautions Personal precautions can reduce exposure to the Q fever microbe and possibly prevent it from spreading within the workplace: Access to workplaces with increased risk of Q fever should be restricted to workers required to be there. Animal tissue should be handled with care, especially tissue involved in birth. Protective clothing should be worn by workers exposed to animal tissue, especially when animals give birth. Wear disposable gloves and sleeves. Contaminated clothing should be labelled with a biohazard warning and washed using laundry procedures for disinfection. No eating, drinking, smoking, or nail biting should be allowed in animal holding facilities. Hands should be washed frequently. Wash animal manure, urine, milk and other body fluids from equipment and disinfect where possible. Keep all “barn clothing” or protective equipment in the barn, not worn in the house. Wash separately in hot water. Production and exposure to aerosols from animal tissues should be minimized. Steps may include to: bury and compost afterbirth or stillborns (or according to local regulations), compost manure for at least 90 days, not spread manure on windy days, and restrict access to barns where there are infected animals (particularly children, pregnant women, elderly, and those with compromised immune systems). Respiratory protection devices such as a fit-tested N-95 (or comparable) respirator suitable for preventing aerosol inhalation should be used by workers at increased risk of inhaling contaminated droplets. When using respirators, be aware of respirator fit, selection and care, and always use as part of a personal protection program. Acceptable laboratory techniques as outlined in Canadian Biosafety Standard, 2nd edition, and the Canadian Biosafety Handbook, 2nd edition should be used in research or diagnostic laboratories that process blood and tissue from animals or patients with Q fever. Do not drink non-pasteurized milk and milk products. Workplace hygiene Procedures should be developed to prevent the release and spread of the Q fever microbe within the workplace. Each workplace should have procedures to disinfect or sterilize areas that may be contaminated with the Q fever microbe. In medical research laboratories associated with hospitals, animals should be kept in separate facilities to reduce the possibility of the Q fever microbe spreading to staff and patients. Use of common elevators and loading docks should be avoided. Pregnant ewes should not be used in research laboratories unless they have negative antibody tests for Q fever. Biosafety containment equipment and facilities should be used in laboratories as recommended in Canadian Biosafety Standard, 2nd edition, and the Canadian Biosafety Handbook, 2nd edition. When livestock gives birth, they should be confined and closely observed. The placenta and other birth tissues should be collected before the animals eat them and disposed of safely. If possible, have birthing occur in an indoor space that can be cleaned and disinfected. Infectious waste should be packaged in puncture-proof, leakproof containers that are clearly labelled and sterilized before disposal according to procedures developed for biological hazards. Surfaces, floors, and walls contaminated with fluids or dust from animals should be disinfected using procedures established for infection control."""
