If you have severe breathing difficulty, significant coughing of blood, or another medical emergency, seek emergency medical care.

Tuberculosis treatment, insurance regulations, costs, and public-health recommendations can change. Readers should verify current information with Swiss healthcare providers, insurers, and official Swiss health authorities.

Introduction

Tuberculosis (TB) is an infectious disease caused by bacteria belonging to the Mycobacterium tuberculosis complex. Although Switzerland has a relatively low tuberculosis incidence compared with many countries around the world, TB continues to occur every year.

According to Switzerland's Federal Office of Public Health (FOPH), the country recorded 522 tuberculosis cases in 2025, corresponding to an incidence of approximately 5.74 cases per 100,000 inhabitants. The FOPH infectious-disease dashboard shows that this represented an increase compared with 2024.

The FOPH also reported in September 2026 that the number of TB cases recorded in Switzerland in 2025 was the highest since 2018. The agency noted that tuberculosis particularly affects people of foreign origin, highlighting the importance of prevention, early detection, diagnosis, and treatment.

This does not mean that tuberculosis is widespread throughout Switzerland. Rather, it remains an important infectious disease that requires continued surveillance and appropriate medical management.

For residents, immigrants, international students, workers, refugees, travelers, and other people living in Switzerland, understanding TB symptoms, testing, treatment, prevention, and health insurance coverage can help with early medical care.

This guide explains tuberculosis cases in Switzerland, how TB spreads, symptoms, diagnosis, treatment, costs, insurance coverage, risk factors, prevention, and recovery.

How Many Tuberculosis Cases Are There in Switzerland?

Switzerland has historically had a relatively low rate of tuberculosis compared with countries where TB transmission is more common.

The FOPH currently describes Switzerland as seeing around several hundred tuberculosis cases each year. Its general tuberculosis information page states that Switzerland has approximately 550 cases annually, although the precise number varies from year to year.

For 2025, the FOPH dashboard reports:

These figures describe reported tuberculosis cases and should not be interpreted as meaning that every person in Switzerland has the same risk.

The distribution of TB is affected by factors such as country of origin, previous exposure, immune status, living conditions, age, and other epidemiological circumstances.

The FOPH states that most tuberculosis cases in Switzerland occur among people who originated from countries where TB remains more common.

Is Tuberculosis Common in Switzerland?

Tuberculosis is not considered highly prevalent in Switzerland, but it has not been eliminated.

The Swiss incidence remains relatively low by international standards. The World Health Organization reported an estimated TB incidence of approximately 5.4 cases per 100,000 population for Switzerland in 2023.

European surveillance data also demonstrate Switzerland's comparatively low notification rate. The European Centre for Disease Prevention and Control reported 434 notified TB cases in Switzerland in 2023, corresponding to a notification rate of 4.9 per 100,000 population.

Differences between surveillance datasets can occur because of reporting definitions, publication dates, revisions, and differences between estimates and nationally reported notifications.

The important point is that TB remains present and requires continued public-health surveillance.

Why Does Tuberculosis Still Occur in Switzerland?

Several factors can contribute to TB cases occurring in Switzerland.

These include:

Previous exposure to TB in countries with higher transmission

Migration from countries with higher TB incidence

Reactivation of a previous latent infection

Close contact with someone who has infectious TB

Weakened immune systems

Certain medical treatments that suppress immunity

Crowded living conditions

Healthcare or laboratory occupational exposure

Long-term exposure in environments where TB transmission occurs

Switzerland's FOPH specifically notes that most cases occur among people originating from countries where TB is still widespread, including countries in Africa and Asia.

This information should not be interpreted as meaning that nationality itself causes tuberculosis. TB infection depends on exposure and individual risk factors.

What Is Tuberculosis?

Tuberculosis is an infectious disease caused mainly by Mycobacterium tuberculosis.

The lungs are the most commonly affected organs. The FOPH states that approximately 80% of TB cases affect the lungs, although tuberculosis can also occur elsewhere in the body.

TB can affect:

Lungs

Lymph nodes

Kidneys

Bones

Spine

Brain

Liver

Digestive organs

Other tissues

Pulmonary tuberculosis is particularly important from a public-health perspective because people with infectious pulmonary or laryngeal TB can transmit bacteria through the air.

How Does Tuberculosis Spread?

Tuberculosis is primarily transmitted through the air.

When a person with infectious pulmonary or laryngeal tuberculosis coughs, bacteria-containing particles can enter the surrounding air.

A person nearby may inhale these particles.

However, TB transmission is not the same as catching a common cold from a brief encounter.

The FOPH explains that people involved in transmission usually need to remain in the same room for several hours for infection to occur.

Risk depends on factors such as:

Whether the infected person has infectious pulmonary TB

How long people remain together

Ventilation

Amount of bacteria released

Treatment status

Environmental conditions

The exposed person's immune system

People with latent TB infection do not normally transmit tuberculosis to others.

Active Tuberculosis vs Latent TB Infection

Understanding the difference between active TB disease and latent TB infection is important.

Active Tuberculosis

Active TB occurs when tuberculosis bacteria are multiplying and causing disease.

Possible symptoms include:

Persistent cough

Fever

Night sweats

Weight loss

Fatigue

Reduced appetite

Chest pain

Coughing up blood in some cases

People with infectious pulmonary TB may transmit the disease to others.

Latent Tuberculosis Infection

Latent TB infection means that a person has been infected with TB bacteria but does not have active TB disease.

People with latent infection generally:

Have no TB symptoms

Do not normally spread TB

May later develop active TB disease

The FOPH explains that only approximately 5–10% of newly infected people develop TB disease, usually within two years, although disease can develop later.

Certain people, particularly those with weakened immune systems, have a higher risk of progressing from infection to active disease.

Symptoms of Tuberculosis

TB symptoms can develop gradually.

Common symptoms of pulmonary tuberculosis include:

Persistent cough

A cough that continues for several weeks should be medically evaluated, especially when accompanied by other symptoms.

Fever

Some people with active TB develop recurring or persistent fever.

Night sweats

Night sweating can occur with tuberculosis but is not specific to TB.

Unexplained weight loss

Unexpected weight loss may occur because of prolonged infection and reduced appetite.

Fatigue

People with active TB can experience significant tiredness and weakness.

Chest pain

Chest discomfort may occur, particularly when the lungs or surrounding tissues are affected.

Coughing blood

Coughing blood can occur in pulmonary TB and requires prompt medical assessment.

The presence of one of these symptoms does not automatically mean a person has tuberculosis. Many other illnesses can cause similar symptoms.

Tuberculosis Outside the Lungs

TB can also affect organs outside the respiratory system.

This is called extrapulmonary tuberculosis.

Examples include:

TB of the lymph nodes

Bone TB

Spinal TB

Kidney TB

TB meningitis

Abdominal TB

Symptoms depend on the affected organ.

For example, spinal TB may cause persistent back pain, while TB meningitis can cause neurological symptoms.

Because extrapulmonary TB can resemble other medical conditions, diagnosis may require specialized testing.

Who Has a Higher Risk of Tuberculosis?

TB can affect anyone who becomes infected, but certain groups have greater risk of infection or progression to active disease.

Higher-risk groups can include:

People who have lived in countries with high TB incidence

Close contacts of people with infectious TB

People with weakened immune systems

People living with HIV

Organ transplant recipients

People taking certain immunosuppressive medicines

Some healthcare workers

Laboratory workers

People living in crowded conditions

People with previous TB infection

Risk assessment should be individualized by a healthcare professional.

How Is Tuberculosis Diagnosed in Switzerland?

Diagnosis depends on whether doctors suspect active TB, latent TB infection, or extrapulmonary disease.

Medical History

A healthcare professional may ask about:

Symptoms

Previous TB exposure

Travel

Country of origin

Previous TB treatment

Medical history

Immune-system conditions

Medication

Contact with someone diagnosed with TB

Chest X-Ray

A chest X-ray may be used when pulmonary tuberculosis is suspected.

It can identify abnormalities that require further investigation.

However, an abnormal X-ray does not by itself prove that someone has tuberculosis.

Sputum Testing

People suspected of having pulmonary TB may be asked to provide sputum samples.

Laboratories can use different methods to:

Detect TB bacteria

Culture the organism

Identify drug resistance

Support confirmation of active disease

Molecular Testing

Modern molecular tests can help detect Mycobacterium tuberculosis and, in appropriate circumstances, identify resistance to certain medications.

Blood Testing

Blood-based tests can be used in some circumstances to assess TB infection, particularly latent TB infection.

Further Testing

Depending on symptoms, doctors may order:

CT scans

Bronchoscopy

Tissue sampling

Cerebrospinal fluid testing

Urine testing

Other specialized laboratory investigations

The exact diagnostic pathway depends on the suspected form of tuberculosis.

Tuberculosis Treatment in Switzerland

Tuberculosis is generally treatable with appropriate antibiotics.

The FOPH states that TB is usually well treatable with a course of several months of specialized antibiotics. Drug-resistant disease can require longer and more complex treatment.

Treatment depends on:

Whether TB is active or latent

The location of disease

Drug susceptibility

Previous treatment

Other medical conditions

Age

Medication interactions

Treatment response

Standard Treatment for Drug-Susceptible TB

For many forms of drug-susceptible pulmonary TB, treatment uses a combination of several medicines.

Common first-line drugs include:

Isoniazid

Rifampicin

Pyrazinamide

Ethambutol

Treatment is commonly divided into an initial phase followed by a continuation phase.

A standard course for uncomplicated drug-susceptible pulmonary TB is often around six months, although treatment can differ depending on the patient's circumstances.

Some patients require longer treatment.

Patients should never stop TB medication simply because they begin to feel better.

Stopping treatment prematurely can contribute to treatment failure, relapse, and drug resistance.

Drug-Resistant Tuberculosis

Drug-resistant TB occurs when tuberculosis bacteria are resistant to one or more medications.

This can make treatment substantially more complicated.

Doctors may perform drug-susceptibility testing to determine which medicines are likely to work.

Treatment for drug-resistant TB can involve:

Specialized antibiotic combinations

Longer treatment

More frequent monitoring

Specialist infectious-disease care

Monitoring for medication side effects

Drug-resistant TB should be managed by experienced healthcare professionals.

Patients should not attempt to modify or discontinue treatment without medical supervision.

Is Tuberculosis Treatment Covered by Swiss Health Insurance?

For people enrolled in Switzerland's mandatory basic health insurance system, medically necessary healthcare for tuberculosis is generally covered according to the applicable rules of the Swiss health insurance system.

Depending on the circumstances, care can include:

Medical consultations

Diagnostic examinations

Laboratory testing

Imaging

Specialist consultations

Prescription medicines

Hospital treatment

Follow-up care

However, covered does not necessarily mean completely free.

Patients can still have financial responsibilities through the applicable deductible and cost-sharing system.

Swiss Health Insurance and TB Costs

Switzerland's compulsory basic health insurance system is governed by the Federal Health Insurance Act, commonly referred to as LAMal in French or KVG in German.

Patients can generally have several forms of cost-sharing.

Franchise

The franchise is the annual deductible that the insured person generally pays before the insurer begins reimbursing covered healthcare expenses.

Adult deductible options include different levels, with CHF 300 being the standard ordinary franchise and higher voluntary franchises also available.

Co-Payment

After the applicable franchise has been reached, insured persons generally pay a percentage of covered costs as a co-payment, subject to the applicable annual limit.

Hospital Contribution

A daily contribution can also apply to inpatient hospital stays under certain circumstances.

Therefore, a person diagnosed with TB should not assume that the entire cost of treatment will be paid directly by the insurer without any patient contribution.

How Much Does TB Treatment Cost in Switzerland?

There is no single price for tuberculosis treatment.

The total cost can vary considerably.

Factors include:

Number of consultations

Diagnostic testing

Imaging

Laboratory investigations

Medication

Hospitalization

Disease severity

Drug resistance

Treatment duration

Complications

Specialist involvement

A straightforward outpatient case can have very different costs from a complicated drug-resistant TB case requiring hospitalization.

For this reason, online cost estimates should be treated as illustrations rather than guaranteed prices.

Does TB Require Hospitalization?

Not every person with tuberculosis needs to stay in a hospital.

Hospital treatment may be considered when:

The patient is seriously ill

There are significant respiratory problems

Complications develop

Drug-resistant TB requires specialized management

Intensive monitoring is needed

Infection-control measures require inpatient care

The patient's overall medical condition makes hospitalization necessary

Some patients can receive treatment as outpatients.

The decision is made by healthcare professionals according to the individual's medical condition and public-health circumstances.

Tuberculosis Treatment for International Students

International students living in Switzerland should pay particular attention to their health insurance arrangements.

Depending on their legal status and circumstances, students may be required to have Swiss basic insurance or may qualify for an exemption based on an equivalent recognized insurance arrangement.

A student who develops suspected TB should seek medical evaluation rather than delaying treatment because of concerns about cost.

Potentially covered services can include medically necessary:

Doctor visits

Diagnostic testing

Laboratory examinations

Prescription medicines

Hospital care

Specialist treatment

Students should confirm their individual insurance status and coverage with their insurer or relevant Swiss authority.

TB Treatment for Expats and Foreign Workers

Foreign workers who are residents and subject to Switzerland's compulsory health insurance system generally receive medically necessary healthcare under the same basic insurance framework.

This can include tuberculosis diagnosis and treatment.

The important issue is not nationality alone but whether the person is subject to the Swiss mandatory insurance system and whether the particular medical service is covered under the applicable rules.

People moving to Switzerland should arrange required health insurance promptly and verify their specific obligations.

Tuberculosis and Occupational Exposure

Some occupations can involve increased exposure to TB.

Examples may include:

Healthcare workers

Laboratory workers

Certain hospital employees

Workers involved in TB diagnosis or treatment

Where tuberculosis is associated with occupational exposure, other insurance or occupational-health rules may become relevant depending on the circumstances.

A healthcare professional or employer's occupational-health service can provide guidance about exposure assessment and appropriate testing.

What Happens After a TB Diagnosis?

After diagnosis, treatment is only one part of TB management.

Healthcare professionals may also consider:

Infectiousness

Contact investigation

Follow-up testing

Treatment adherence

Medication side effects

Drug resistance

Underlying medical conditions

Recovery progress

Close contacts may be assessed where appropriate.

This helps identify people who may have been infected and may benefit from testing or preventive treatment.

Can Tuberculosis Be Cured?

Yes, tuberculosis can often be successfully treated and cured when the appropriate treatment is completed.

The outcome depends on:

Type of TB

Drug susceptibility

Stage of disease

Location of infection

Overall health

Immune status

Medication adherence

Timely diagnosis

Drug-resistant TB can be considerably more difficult to treat.

Completing the prescribed treatment is one of the most important factors in preventing treatment failure and recurrence.

Recovery After Tuberculosis

Recovery can continue after the bacteria have been successfully treated.

Some patients recover without lasting problems, while others may experience longer-term effects depending on the severity and location of their disease.

Possible issues include:

Fatigue

Reduced exercise tolerance

Lung damage

Persistent respiratory symptoms

Weight loss

Psychological stress

Follow-up appointments allow healthcare professionals to assess recovery and identify complications.

How Can Tuberculosis Be Prevented in Switzerland?

TB prevention involves several strategies.

Early Diagnosis

Detecting active TB early can reduce the opportunity for transmission.

Completing Treatment

Patients should take medications exactly as prescribed.

Contact Investigation

People who have been significantly exposed to infectious TB may be assessed by healthcare professionals.

Good Ventilation

Adequate ventilation can reduce the concentration of airborne infectious particles in enclosed environments.

Screening

People at increased risk may be offered TB testing depending on their circumstances.

Infection Control

Healthcare facilities use appropriate infection-control measures when infectious TB is suspected or confirmed.

Is There a TB Vaccine in Switzerland?

The FOPH states that tuberculosis vaccination is not routinely available in Switzerland.

The
