Rocky Mountain Spotted Fever – Symptoms, Treatment, and Diagnosis
Symptoms, Treatment, and Diagnosis. Rocky Mountain Spotted Fever is caused by a virus that is transmitted to humans by mosquitoes. It is a disease that can be serious if left untreated. It can cause life-threatening complications and even death.
Symptoms
Among the most common symptoms of Rocky Mountain Spotted Fever are a high fever, muscle aches, and vomiting. The disease is caused by bacteria and is spread to humans through the bite of an infected tick. It affects both children and adults and is not fatal if treated promptly. However, it can cause serious damage to internal organs and even death.
The disease is often mistaken for other illnesses such as the flu or cold. The rash that develops is also characteristic of Rocky Mountain spotted fever and can appear on the wrists, ankles, and arms. Some RMSF rashes look like pinpointed dots on the skin. The rash may or may not have red spots.
The best way to prevent Rocky Mountain spotted fever is to avoid ticks. You can spray a repellent on your clothing and on exposed skin. These products have to be labeled and approved by the Environmental Protection Agency. They are designed to keep ticks from attaching to the body and should be used in accordance with the instructions.
The CDC recommends treating Rocky Mountain spotted fever with antibiotics. The recommended drugs are doxycycline and chloramphenicol. These drugs are effective for adults and children.
Treatment should start as soon as possible. A primary care physician may prescribe the drug. In severe cases, critical-care specialists may be needed. In addition, an MRI or lumbar puncture may be necessary. Other tests may include CBC, platelet counts, and liver function tests.
The first sign of RMSF is a sudden high fever, which can range from 102 to 103 oF. This is followed by abdominal pain, nausea, and vomiting. If left untreated, the disease can lead to kidney failure, kidney damage, and even death.
The rash that develops in patients with Rocky Mountain spotted fever is called the petechial rash. In about 35 percent to 60 percent of infected individuals, this rash is visible. Other people do not develop the rash.
The rash that is present in Rocky Mountain spotted fever patients can be painful and itchy. The rash tends to spread to the palms and soles of the feet. It can also be found on the arms, legs, and torso.
Diagnosis
Getting the diagnosis of Rocky Mountain Spotted Fever (RMSF) is important because it is a disease that can be fatal if left untreated. It is a tick-borne disease that is spread by the bite of infected American dog ticks. It affects people who live in areas where ticks are common, such as the south and west.
Symptoms of Rocky Mountain spotted fever begin within 3 to 12 days after the tick bite. They can be vague and difficult to distinguish from other illnesses. If your healthcare provider suspects you are infected, they will test your blood for antibodies to the bacteria that cause RMSF. If you test positive for the bacteria, they will prescribe antibiotics.
Although it can be difficult to diagnose, the disease is curable and should be treated immediately. The most common treatment for Rocky Mountain spotted fever is doxycycline, which is usually prescribed for adults, but is effective in treating children as well. Taking the drug as soon as possible will prevent serious complications.
The symptoms of RMSF include a rash that starts on the wrists, ankles, and soles. Patients may also experience abdominal pain, muscle aches, diarrhea, and headaches.
Rocky Mountain spotted fever is a very rare disease that is not common in Minnesota. However, there have been isolated cases in various parts of the state. It should be considered in anyone with a compatible clinical presentation.
There are no vaccines for Rocky Mountain spotted fever. Using a combination of antibiotics, mechanical ventilation, and blood transfusion can be used to treat the disease. The most common drugs used are doxycycline, chloramphenicol, and tetracycline. These drugs are usually given by mouth but can be given intravenously if the infection becomes severe.
If you’re bitten by an infected tick, you should visit your doctor as soon as possible. This will ensure that you get the proper diagnosis of Rocky Mountain spotted fever and that you can start treatment promptly. It is not uncommon for the first few days of the illness to go undiagnosed. A blood test will help confirm the diagnosis and can be performed 7 to 10 days after the initial onset of symptoms.
Treatment
RMSF, or Rocky Mountain Spotted Fever, is a disease caused by Rickettsia rickettsii. It is transmitted by the bite of infected ticks. The infection leads to vasculitis or damage to the blood vessels. The most common symptoms of RMSF are high fever, muscle pain, and rash.
The goal of treatment for RMSF is to start treatment within five days of the onset of the illness. Failure to treat the infection early can lead to severe complications and even death.
The first line of treatment for RMSF is doxycycline. Doxycycline is a broad-spectrum antibiotic that can be prescribed to patients of all ages. This drug is a preferred choice because it does not cause tooth staining. A second choice is tetracycline. This drug is prescribed at 22 mg/kg of body weight, three times a day.
In addition to doxycycline, chloramphenicol is also used to treat RMSF. However, this drug has been associated with a higher mortality rate in people.
The diagnosis of Rocky Mountain Spotted Fever can be difficult. The clinical manifestations of the disease can be vague and similar to other viral illnesses. For this reason, clinicians need to have an index of suspicion to make a diagnosis.
There are blood tests that can be performed to help diagnose RMSF. These tests test for bacteria that cause the disease. The most sensitive test is the Indirect Immunofluorescent Assay (IFA), which requires two blood samples. If the IFA is positive, then the patient has RMSF. If the IFA is negative, then the patient may not have RMSF. Other tests are less sensitive and do not provide a definitive diagnosis.
If the blood test is positive, then the doctor may perform further diagnostic tests. This includes a PCR test of circulating blood. This test can be useful in RMSF because it may be detectable at an early stage of infection.
If the test is negative, then the person should be referred to an infectious disease specialist. Depending on the diagnosis, treatment may include blood transfusions, mechanical ventilation, or a combination of these treatments.
If the infection is not treated, the person may develop a serious skin rash. This rash can spread rapidly to the trunk and soles. It may begin as early as the first day of illness and may last for several weeks.
Life-threatening complications
Several life-threatening complications of Rocky Mountain Spotted Fever (RMSF) can be developed if the disease is not treated quickly. These complications include microcirculatory vasculitis and myocarditis. In addition, untreated RMSF can result in hearing loss and vision loss.
Rickettsia rickettsii is a bacteria that is transmitted to humans by the bite of infected ticks. There are two primary vectors: the American dog tick and the Rocky Mountain wood tick.
The infection is most common during the spring and summer. The first symptoms usually appear after a few days. Typically, these symptoms are fever, headache, nausea, and loss of appetite.
During treatment, the patient is given antibiotics. The antibiotics can be taken by mouth or intravenously. For children, the preferred drug is doxycycline.
Oftentimes, a patient will not remember the tick bite. This complicates the diagnosis of the disease. The goal of treatment is to begin therapy within five days of being infected.
In the case of a severe infection, patients may require extended hospitalization. In addition to the symptoms of RMSF, the disease can also affect the heart, renal system, respiratory system, central nervous system, and muscles. RMSF can also cause gangrene, which can lead to amputations.
Most Rocky Mountain spotted fever cases occur in people who spend a lot of time outdoors. This is because the bacteria can spread through the bloodstream and lymphatic vessels. This can also lead to other infections if the person is not properly treated.
The disease can be fatal. Although the death rate has decreased, a significant number of Rocky Mountain spotted fever deaths still occur. The most common causes of death are delayed diagnosis and failure to treat with antibiotics.
RMSF is the most lethal form of tick-vectored illness in the United States. If not treated, the patient can suffer from complications that can include vision loss, hearing loss, and nerve damage.
The first step in diagnosing RMSF is to perform a clinical exam. In addition, a skin or blood test may be performed. RMSF is usually not diagnosed until seven to ten days after the onset of the disease.
