Have you ever heard of this disease called Q Fever? Probably not, right? Because this is not a disease that is seen very often in our country. But, especially if you are someone who works with animals, farm animals, or lives in such an environment, it is very important to be a little aware of this. In this article today, we will talk about what this Q fever is, how it develops, what are the symptoms, and how we can protect ourselves from it.
What is Q Fever? Simply put...
Q fever is a disease that we get by breathing in dust particles containing a bacterium called `Coxiella burnetii` or by consuming products from infected animals. This bacterium is mainly found in the bodies of animals such as sheep, goats, and cattle. The bacteria can accumulate in the soil where these animals live. It can then be transmitted to humans through dust particles released from that soil, or through the milk, feces, and especially the fluids released during childbirth.
Why is it called Q fever? What does the name mean?
This is also a bit of a strange story. The letter 'Q' in Q fever stands for 'Query' . 'Query' means 'question' or 'inquiry'. In the past, in Australia in the 1930s and then in America in the 1940s, when people started getting this strange fever, doctors initially couldn't figure out what was causing it. So they had a lot of 'questions' about this fever. That's why it was called 'Query Fever' or Q fever. Very simple, right?
What is chronic Q fever? Is it dangerous?
Yes, this is a bit of a concern. The word 'chronic' means long-term . So, chronic Q fever is a more serious, long-term form of Q fever. It can affect your heart, blood vessels, bones , and other vital organs. This chronic condition occurs in a very small percentage of people infected with the C. burnetii bacteria, between 1% and 5% .
One problem with this is that this chronic condition can develop months or even years after the initial Q fever symptoms have resolved. Some people may not show any symptoms during the initial infection but later develop chronic Q fever. The most common complication of chronic Q fever is an infection of the lining of the heart. Doctors call it ``endocarditis''. This is a potentially life-threatening complication.
Q What happens when you get a fever?
Q fever can cause a variety of symptoms. However, the most common symptoms are those of a common cold, such as fever and body aches . The bacteria `C. burnetii` can infect your lungs, heart, brain, bones, or other parts of your body. Symptoms vary accordingly. Some people experience severe fatigue.and other symptoms can last for months, even years. As mentioned earlier, chronic Q fever can be life-threatening.
Who is most likely to get Q fever?
Q flu mostly affects people who live on farms or who have close contact with farm animals . For example, if you are a veterinarian, a person who helps with the birth of calves, a person who works on a farm, a ranch, or a slaughterhouse, you are at higher risk of contracting the disease. This is because these people are often in contact with infected animals and the environment they live in.
Q Who is at higher risk of becoming seriously ill from the flu?
Some people are more likely to develop serious conditions from Q fever, especially:
- Pregnant women are at increased risk of complications during pregnancy and miscarriage.
- You are at higher risk of developing chronic Q fever if you have the following conditions:
- If you have previously had `(Endocarditis)` (inflammation of the inner lining of the heart).
- If there are problems with the heart valves.
- If you have aneurysms (weakening and bulging of blood vessel walls) in your blood vessels.
- If kidney function is poor (Renal insufficiency).
- If you have a permanently implanted device (vascular prosthesis) to strengthen blood vessels and improve blood flow.
- If your immune system is weak (for example, those infected with HIV, cancer patients, those taking immunosuppressive drugs).
Q How common is the flu?
Q fever is actually a very rare disease . For example, even in a country like America, only about 200 cases are reported per year. It is not reported very often in Sri Lanka either. However, it is important for those in risk groups to be aware.
Q What are the symptoms of a fever?
The symptoms of Q fever vary depending on the initial (acute) stage and other conditions that may occur later.
Symptoms of Acute Q fever
These symptoms usually begin to appear between 3 and 30 days after the bacteria enter the body. They are often similar to those of a cold or flu.
- High fever
- Extreme tiredness and fatigue
- Chills
- Sweating
- Body aches, muscle pain
- Sensitivity to light, blue eyes (Photophobia)
- Very severe headache
- Nausea and vomiting
- Diarrhea
- Cough
- Chest pain
- Stomach pain
- Red spots under the skin (Purpura)
- Difficulty breathing (Dyspnea)
Sometimes, this severe Q fever can cause conditions such as lung infections (Pneumonia), inflammation of the brain or the membranes covering the brain (Encephalitis or Meningitis), or inflammation of the liver (Hepatitis).
Symptoms of Q fever fatigue syndrome (QFS)
About 20% of people who get Q fever may develop fatigue and other symptoms that last for months, sometimes years, after the initial infection. This is called Q fever fatigue syndrome.
- Very tired
- Headache
- Sweating
- Joint pain
- Muscle pain
Symptoms of Chronic Q fever
Chronic Q fever begins months, or even years, after an initial infection with the C. burnetii bacteria. It can develop even if you have no symptoms during the initial infection. It most commonly affects the heart, heart valves, and blood vessels, but symptoms can vary depending on the part of the body affected.
- Low-grade fever
- Night sweats
- Weight loss
- Fatigue
- Difficulty breathing
- Swelling of the legs or feet
Q What causes fever?
The main cause of Q fever is the bacterium Coxiella burnetii . This bacterium can live in animals, especially cattle, sheep, and goats, without showing any symptoms. The body fluids of infected animals (such as urine, feces, milk, and amniotic fluid) can contaminate the soil they live in. People become infected with this bacterium mainly by breathing in dust particles or water vapor from contaminated soil.
Q How is the flu transmitted?
The main way that Q fever is spread is by breathing in dust or water vapor contaminated with the `C. burnetii` bacteria . This can happen if you live or work in an area where animals live, especially farm animals. Because the `C. burnetii` bacteria can travel some distance through the air, you don't have to be in direct contact with animals to get it.
Other, but less common, ways that Q fever can be transmitted are:
- Eating or drinking unpasteurized dairy products (e.g. milk, cheese, ice cream).
- Bite from an infected tick .
- From a pregnant mother to her child during pregnancy or childbirth .
- Through a blood transfusion (this is very rare).
Important: Q fever is not usually transmitted from person to person . There have been rare reports of transmission from a pregnant mother to her baby.
Q How is fever diagnosed?
Your doctor will diagnose Q fever by asking about your symptoms , reviewing your medical history , and testing a blood sample . They may also ask if you live or work with animals.
Test results for C. burnetii can take several weeks to come back, so if your doctor suspects you have Q fever, they may start treatment without waiting for the test results.
Q What tests are done for fever?
To test for Q fever, your doctor will take a sample of your blood using a small needle. This sample will be sent to a lab to look for signs (antibodies) of a C. burnetii infection. They may also try to culture the C. burnetii bacteria from your sample.
You may need to give blood samples several times over a period of time to get a definitive diagnosis.
Q How is fever treated?
Acute Q fever is treated with antibiotics . Chronic Q fever is often treated with a combination of antibiotics and anti-inflammatory medications, but it can be more difficult to treat. Your doctor will develop a specific treatment plan based on your condition.
If you are diagnosed with Q fever and have pre-existing heart valve or blood vessel conditions, talk to your doctor about early treatment to reduce your risk of chronic Q fever.
What medications/treatments are used?
The doctor may prescribe the following medications:
- `( Doxycycline ( Doxycycline) ) `
- `(Hydroxychloroquine)`
- `(Trimethoprim-sulfamethoxazole (TMP-SMX))`
- `(Rifampin)`
- `(Fluoroquinolones)` (e.g. `(Ciprofloxacin)`, `(Ofloxacin)`)
- `(Clarithromycin)`
Q Can fever be completely cured?
Yes, most people can recover completely from acute Q fever with antibiotics. However, even in the small number of people who develop acute Q fever, symptoms can persist for months or even years, even if treated. Chronic Q fever is a little more difficult to treat.
How can I reduce my risk of Q fever?
There are several things you can do to reduce your risk of Q fever:
- Wear a mask and gloves when handling animal bodily fluids, especially those released during childbirth .
- Avoid eating or drinking unpasteurized dairy products .
- Some studies suggest that screening and treating heart valve problems in people diagnosed with Q fever can prevent chronic Q fever.
- If you work in a high-risk job and live in an area where a vaccine for Q fever is available (currently only available in Australia), ask your doctor about getting vaccinated.
If you live or work around farm animals, and you are at increased risk for complications from Q fever (e.g., people with heart valve or blood vessel problems, pregnant women, people with weakened immune systems), talk to your doctor about how to prevent Q fever.
What should I expect if I have Q fever?
Symptoms of Q fever can last for a long time , from 10 to 90 days . However, most people recover completely . If you are prescribed antibiotics, you will need to take them for at least two weeks. About 1 in 5 people (20%) may develop a feeling of fatigue (`(Q fever fatigue syndrome)`) that lasts for months or years.
A very small number of people (between 1% and 5%), especially those with other underlying medical conditions, can develop chronic Q fever. If you have chronic Q fever, you may need to be treated for 18 months or longer .
Q What are the complications of fever?
Complications can occur with both acute Q fever and chronic Q fever. However, these are more common and usually more serious in chronic Q fever. Complications include:
- A weakened, bulging artery (Aneurysm)
- Arterial fistula, a condition in which blood flows incorrectly
- Endocarditis
- Scarring of the lungs (Fibrosis)
- Acute respiratory distress syndrome (ARDS)
- Heart failure
- Bone Infection (Osteomyelitis)
- Miscarriage
- Low birth weight
Q What is the outlook for the flu?
The prognosis for acute Q fever is generally good if treated with antibiotics. The mortality rate for acute Q fever is between 0.5% and 1.5% . People who develop chronic Q fever are at higher risk of complications and death. The mortality rate for chronic Q fever is between 12% and 25% .
How do I take care of myself?
If you are diagnosed with Q fever, it is very important to take all prescribed medications on time . Ask your doctor how to manage your symptoms and whether there are ways to reduce the risk of long-term symptoms or chronic Q fever.
When should I see a doctor?
If you work or live with cattle, goats, or sheep, and you develop symptoms of Q fever, see a doctor immediately . If you have symptoms of chronic Q fever, and you think you may have been exposed to the `C. burnetii` bacteria in the past (even if it has been a while), tell your doctor.
What questions should I ask my doctor?
- Should I take medication in advance to reduce the risk of chronic Q fever?
- Should I get tested for heart and blood vessel problems?
- How do I take this medicine?
- When should I come see you again?
- What can I do to manage my symptoms?
Finally, things to remember (Take-Home Message)
Although Q fever is a rare disease, it's important to be aware of it and take protective measures if you work or live in a high-risk environment. Simple things like wearing a mask, gloves, and avoiding unpasteurized dairy products can make a big difference, especially when working with farm animals .
Although chronic Q fever only affects a small number of people, it can cause life-threatening complications. So, if you think you may have Q fever, or if you have any concerns about it, don't hesitate to seek medical advice . Telling your doctor about your health history and work history will help them understand your risk factors and provide the best treatment.
👩🏽⚕️ Additional questions (FAQs)
💬 Is 'Q Fever' a disease transmitted by cattle?
Not just from cows! This is a fever caused by a dangerous bacteria called Coxiella burnetii. This bacteria is mostly found in the bodies of cows, sheep, and goats. These germs are found in the placentas and fluids that these animals shed when they give birth. We get sick when they dry up and enter our lungs as dust when we breathe them in.
💬 Do you stay in bed when you have this fever?
Surprisingly, 50% of people who contract the virus do not develop any symptoms. However, others may develop a high fever, headache, fatigue, muscle aches, and a severe, disabling lung infection (pneumonia) a few days later.
💬 Will this disease never get better?
Most people recover completely in a few weeks with antibiotics (Doxycycline). But the most dangerous thing is that in about 5% of cases, this bacteria can hide in the heart valves and, years later, cause Chronic Q fever (heart infection - Endocarditis) and kill the patient.
