What kind of doctor treats Typhus?
An infectious disease doctor, a doctor who treats illnesses caused by germs, usually treats typhus. A primary care doctor can start the care, and a hospital team helps when the illness is severe. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is typhus?
Typhus is a group of illnesses caused by bacteria, which are tiny germs. The bacteria spread to people through fleas, lice, and chiggers. Chiggers are the young form of tiny mites.
There are three main types. Flea-borne typhus is also called murine typhus or endemic typhus. Epidemic typhus is also called louse-borne typhus. Scrub typhus is also called bush typhus.
Brill-Zinsser disease is a mild form of epidemic typhus. It happens when the bacteria become active again in a person who was infected before. It is more common in older adults.
Symptoms
The most common symptoms are fever, headaches, and sometimes a rash. Murine typhus may also cause:
- Belly pain and backache.
- A dull red rash that starts on the middle of the body and spreads.
- A dry cough.
- Joint and muscle pain.
- Nausea and vomiting.
The fever can be extremely high and can last up to 2 weeks.
Epidemic typhus may cause high fever, chills, cough, and severe muscle and joint pain. It can also cause a severe headache, low blood pressure, and eyes that hurt in bright light. Some people become confused, less alert, or delirious. Delirium is a state of serious confusion.
In epidemic typhus, the rash starts on the chest and spreads to the rest of the body, but not the palms or soles. The early rash is light rose and fades when you press on it. Later it becomes dull and red and does not fade. People with severe typhus may also get small areas of bleeding into the skin.
Typhus can lead to kidney problems, pneumonia (a lung infection), and damage to the central nervous system, which is the brain and spinal cord.
Causes and who gets it
Murine typhus is caused by bacteria called Rickettsia typhi. People catch it through contact with infected fleas. The bacteria are usually spread from rats to fleas to people.
Murine typhus occurs in the southern United States, including California and Texas. It is often seen in summer and fall. You are more likely to get it if you are around rat feces or fleas, or animals such as cats, possums, raccoons, and skunks.
Epidemic typhus is caused by Rickettsia prowazekii and is spread by body lice. Scrub typhus is caused by Orientia tsutsugamushi and is spread by the bites of infected chiggers.
How doctors diagnose it
Diagnosis is often based on a physical exam and detailed information about your symptoms. You may be asked if you remember being bitten by fleas. If a provider suspects typhus, medicines are started right away. Blood tests are then ordered to confirm the diagnosis.
Treatment
Doctors treat murine and epidemic typhus with antibiotics, which are medicines that kill bacteria. These include doxycycline and tetracycline. Chloramphenicol is much less common. This treatment information covers murine and epidemic typhus only, not scrub typhus.
Tetracycline taken by mouth can permanently stain teeth that are still forming. It is usually not prescribed for children until all of their permanent teeth have grown, or for pregnant women.
People with epidemic typhus may need oxygen and IV fluids, which are fluids given through a vein.
People with epidemic typhus who get treatment quickly should recover completely. Without treatment, death can occur, and people over age 60 have the highest risk. Prompt antibiotic treatment will cure nearly all people with murine typhus.
When to see a doctor
Contact your provider if you develop symptoms of typhus. This serious illness can require emergency care.
Call 911 or go to the emergency room if a person with typhus has a change in mental status (such as new confusion), is hard to wake up, has trouble breathing, or faints. For a child, also get emergency help for fever followed by a change in mental status or a stiff neck or back.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either kind of doctor can review your symptoms and any flea, lice, or travel exposure. They can order first tests and send you to an infectious disease specialist or the hospital when needed.
Common questions
How is typhus spread?
Typhus is spread by fleas, lice, and chiggers. Fleas spread flea-borne typhus, body lice spread epidemic typhus, and chiggers spread scrub typhus. In murine typhus, the bacteria are usually spread from rats to fleas to people.
Can antibiotics treat typhus?
Yes, antibiotics are the treatment for murine and epidemic typhus. Doctors use doxycycline or tetracycline, and chloramphenicol is much less common. Prompt antibiotic treatment will cure nearly all people with murine typhus.
Is typhus deadly?
It can be, depending on the type and on how fast treatment starts. Without treatment, epidemic typhus can cause death, and people over age 60 have the highest risk. Murine typhus is rarely deadly.
Where does murine typhus occur in the United States?
Murine typhus occurs in the southern United States, including California and Texas. It is often seen during the summer and fall. You are more likely to get it around rat feces, fleas, or animals such as cats, possums, raccoons, and skunks.
