Typhus, also called typhus fever, is a name for a group of infectious diseases. These include epidemic typhus, scrub typhus, and murine typhus. People usually start feeling sick one to two weeks after they are exposed. Common symptoms are a fever, a headache, and a rash.

These diseases are caused by specific types of bacterial infection. Epidemic typhus comes from Rickettsia prowazekii bacteria, spread by body lice. Scrub typhus is caused by Orientia tsutsugamushi bacteria, spread by tiny mites called chiggers. Murine typhus is caused by Rickettsia typhi bacteria, spread by fleas.

Scientists have worked on vaccines, but none are widely available for sale. You can prevent typhus by staying away from the small creatures that spread the disease. Doctors treat typhus with an antibiotic medicine called doxycycline. Epidemic typhus often happens in outbreaks where many people live close together and hygiene is poor. It used to be common but is now rare. Scrub typhus is found in places like Southeast Asia, Japan, and northern Australia. Murine typhus occurs in warm, tropical and subtropical parts of the world.

People have known about typhus since at least the year 1528. The name comes from an old Greek word, tûphos. This word meant 'hazy' or 'smoky' and described the confused state of mind of sick people. It is important to know that typhus and typhoid fever are different diseases. They are caused by different bacteria.

Signs and Symptoms of Typhus

The symptoms of typhus can vary depending on the type. Here are some common signs:

Epidemic Typhus Symptoms

Symptoms for epidemic typhus usually start suddenly. This happens about one to two weeks after a person gets infected. They include a high fever and other flu-like feelings. About five to nine days later, a rash often appears on the body. It then spreads to the arms and legs, but usually not the face, palms, or soles of the feet.

As the rash appears, some people might develop problems affecting the brain. These can include being sensitive to light (photophobia) or feeling confused (delirium). In serious cases, a person might even fall into a deep sleep (coma). If not treated, this type of typhus can be very serious.

Scrub Typhus Symptoms

Signs of scrub typhus usually begin one to two weeks after infection. These symptoms include fever, headaches, chills, and swollen lymph nodes. People might also feel sick to their stomach or throw up. A dark, scab-like sore called an eschar can appear where the mite bit them. More severe cases can harm the lungs, brain, kidneys, and heart.

What Causes Typhus?

Several diseases are called "typhus." They are caused by different bacteria and spread by different small creatures.

How Doctors Diagnose Typhus

Doctors find out if someone has typhus mainly through lab tests. The most common test is called an indirect immunofluorescence antibody (IFA) test. This test looks for special proteins called antibodies in a blood sample. Antibodies are made by your body to fight off infections.

Other tests like immunohistochemistry (IHC) or polymerase chain reaction (PCR) can also be used for some types of typhus. However, for scrub typhus, doctors use the IFA test and another test called indirect immunoperoxidase (IIP) assays. These tests help doctors identify the specific bacteria causing the illness.

How to Prevent Typhus

As of 2026, there is no widely available vaccine for typhus. Preventing the disease means avoiding the creatures that spread it.

Preventing Scrub Typhus

Scrub typhus is spread by mites. To avoid it, try not to spend time outdoors in areas where mites are common. You can also treat your clothes with a special bug repellent called permethrin. Using insect repellent on your skin helps keep mites away. It's also a good idea to dress children and babies in clothes that cover their arms and legs. You can also put a mosquito net over strollers for babies.

Preventing Epidemic Typhus

Epidemic typhus is spread by body lice. Lice thrive in crowded places with poor hygiene. If possible, try to avoid very crowded areas. It is important to keep yourself and your clothes clean regularly to kill lice. This also applies to bedding and towels. Do not share any fabric items with anyone who might have lice or typhus. Treating clothing with permethrin can also help kill lice.

Preventing Murine Typhus

Murine typhus is caused by flea bites. To avoid these, make sure your pets do not have fleas. If they do, they should be treated by a vet. Try to avoid contact with wild animals. Use insect repellent to keep fleas away. Wear gloves if you need to handle sick or dead animals. It's also a good idea to take steps to keep rodents and other wildlife out of your home.

Treatment for Typhus

Doctors usually start treating typhus based on symptoms, even before lab tests confirm the diagnosis. This is because early treatment is very important. Without treatment, epidemic typhus can be very serious, especially for older people.

Today, with antibiotics like doxycycline, it is rare for people to die from typhus. Studies have shown that when people with epidemic typhus are given doxycycline, they usually recover well. Another antibiotic, chloramphenicol, has also been used successfully.

Where Typhus is Found Today

According to the World Health Organization, in 2010, very few people died from typhus each year. It was about one death for every 5 million people.

Today, epidemic typhus is rare in most parts of the world. Since the late 1900s, cases have been reported in countries like Burundi, Rwanda, Ethiopia, and Algeria. Some cases have also occurred in parts of South and Central America.

In the United States, most cases of epidemic typhus have happened east of the Mississippi River. A group of cases in Pennsylvania was linked to flying squirrels. This type of typhus, spread from wild animals, is still uncommon in the US. The Centers for Disease Control and Prevention recorded only 47 cases between 1976 and 2010. In October 2018, an outbreak of flea-borne murine typhus was found in downtown Los Angeles, California.

A Brief History of Typhus

Typhus has affected people for many centuries, often during times of war or poor living conditions.

Typhus in Earlier Times

The first clear description of typhus was in 1489 AD. This was during a Spanish battle in Baza. Records from that time describe fever, red spots, confusion, and serious illness. During that battle, 3,000 soldiers died from fighting, but 17,000 more died from typhus.

In old English prisons, a disease called "jail fever" was common. Experts now believe this was typhus. It spread easily when prisoners were crowded into dirty rooms where lice lived. Being sent to prison could often mean a death sentence because of this disease. Sometimes, prisoners even infected people in the courtrooms. In 1759, it was estimated that a quarter of prisoners died from jail fever each year.

Typhus in Modern History

Typhus epidemics happened often across Europe from the 1500s to the 1800s. It was a big problem during wars like the English Civil War and the Napoleonic Wars. During the Thirty Years' War (1618-1648), typhus may have killed more than 10% of the German population.

When Napoleon's army retreated from Moscow in 1812, more French soldiers died from typhus than from battles.

A large typhus outbreak happened in Ireland between 1816 and 1819, during a time of famine. About 100,000 people died. Another major outbreak occurred during the Great Irish Famine from 1846 to 1849. This outbreak, along with typhoid fever, caused about 400,000 deaths. The Irish typhus spread to England, where it was called "Irish fever." It affected people from all walks of life because lice were everywhere.

In the United States, a typhus epidemic happened in Philadelphia in 1837. It also caused deaths in other cities like Baltimore and Memphis between 1865 and 1873. Typhus was a serious killer during the US Civil War. However, typhoid fever was an even more common cause of illness in army camps.

In Canada, the typhus epidemic of 1847 killed over 20,000 people. These were mainly Irish immigrants who had caught the disease on crowded ships while fleeing the Great Irish Famine.

Typhus in the 20th Century

Typhus was common in Poland and nearby countries before World War I (1914–1918). It became a widespread epidemic during the war. While delousing stations helped soldiers on the Western Front, typhus severely affected armies on the Eastern Front. Over 150,000 people died in Serbia alone.

In 1922, a typhus epidemic in Russia reached its peak, with millions of cases. During the Russian Civil War, epidemic typhus killed 2–3 million people, many of whom were civilians.

During World War II, typhus epidemics killed many people. This included German prisoners of war after the Battle of Stalingrad. It also affected those in crowded, unhygienic places like POW camps, ghettos, and Nazi concentration camps. For example, Anne Frank, age 15, and her sister Margot, age 19, died from typhus in the Bergen-Belsen concentration camp.

The first typhus vaccine was created by the Polish scientist Rudolf Weigl. This vaccine did not stop the disease completely but made it less deadly.

Typhus in the 21st Century

In 2018, a murine typhus outbreak spread through Los Angeles County, mainly affecting people experiencing homelessness. In 2019, a city attorney in Los Angeles City Hall was infected with typhus from a flea bite. Pasadena also saw an increase in typhus cases, with 22 in 2018. Over the past decade, murine typhus cases have been rising, with 171 cases in 2022 being the highest number.
