What is Tuberculosis?

Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. In 2022, 10.6 million people fell ill with TB, and 1.3 million died from the disease. One-quarter of the world's population is estimated to be infected with TB bacteria, though most have latent TB (not sick or contagious). TB is curable and preventable, yet it continues to claim lives, particularly in low and middle-income countries.

Symptoms

  • Persistent cough lasting 3+ weeks
  • Coughing up blood or mucus
  • Chest pain when breathing or coughing
  • Unintentional weight loss
  • Fatigue and weakness
  • Fever and night sweats
  • Chills and loss of appetite

Transmission

TB spreads through airborne particles when a person with active pulmonary TB coughs, sneezes, speaks, or sings. Prolonged, close contact with an infected person increases transmission risk. TB is not spread by touching, sharing food, or brief contact. Poor ventilation increases transmission risk.

Contagious Period: People with active pulmonary TB can be contagious until treated for 2-3 weeks; latent TB is not contagious

Prevention

  • Early diagnosis and treatment of active TB cases
  • Treatment of latent TB infection to prevent progression
  • BCG vaccination in high-burden countries (protects children)
  • Good ventilation in indoor spaces
  • Respiratory hygiene (covering mouth when coughing)
  • Isolation of infectious TB patients until no longer contagious
  • Regular screening for high-risk populations
  • UV light or air filtration in healthcare settings

Tuberculosis (TB) is the leading cause of death from a single infectious agent, yet the deaths that underlie this statistic focus solely on those related to the acute disease episode. An emerging body of evidence now recognizes TB as a chronic condition, with consequences extending well beyond treatment completion. This research has primarily examined the long-term disability caused by TB. Physical, psychological and economic seque

Emergency response in jeopardy: The ambulance crisis in South Africa's rural areas

South Africa 2026-04-28
Active

The Rural Health Advocacy Project (RHAP) has revealed that the shortage of ambulances in rural regions compromises patient care. Limited ambulance availability, coupled with vehicles being busy elsewhere, compromises patient care in rural areas. This is according to the Rural Health Advocacy Project (RHAP) in its latest policy brief on Tuberculosis (TB) in rural areas. The report revealed that while patients in rural areas face significant barriers to reaching clinics due to poor road conditions, the problem is worsened by the scarcity of suitable ambulances. In the Eastern Cape, there has been a shortage of 32% of ambulances, while other provinces, such as the North West, face an even greater shortage of 85%. The advocacy organisation stated that while the national standard for ambulance ...

Civil society declares war on diabetes in South Africa

South Africa 2026-04-21
Active

Amanda Mashego was diagnosed with Type 1 diabetes six years ago. Today, she is a diabetes advocate with a significant social media following, and she still describes managing her condition as a 24-hour job she never applied for and cannot resign from. Every meal, every emotion, every bout of exercise requires calculation and adjustment. The mental load, she said, is relentless, and almost entirely invisible to the healthcare system meant to support her. Mashego's story is one of millions playing out largely unseen. Diabetes has become a leading cause of natural death in South Africa, overtaking tuberculosis in recent years. More than half of those living with the condition remain undiagnosed, according to Zukiswa Zimela, communications manager at the Healthy Living Alliance (Heala) at the ...

Improving Latent Tuberculosis Infection Identification and Treatment Adherence

United States Minor Outlying Islands, Baker Island 2026-04-16
Active

While for the past 30 years, the incidence of active tuberculosis (TB) in the US has been lower than the global incidence, untreated latent TB infection (LTBI) is thought to account for the majority of domestic infections. In fact, about 80% of US active TB cases may have progressed from LTBI that was untreated, according to the CDC. Respiratory medicine and public healthcare clinicians can play an important role in screening, diagnosis, treatment, and addressing misconceptions to improve treatme

Bovine tuberculosis, Tunisia

Tunisia 2026-04-20
Active

Six cases of bovine tuberculosis in calves were detected at the Sousse municipal slaughterhouse during routine post-mortem inspection, consistent with Tunisia's endemic bovine tuberculosis, where approximately 1.2–3.24% of officially slaughtered cattle show signs of infection. With 1400–1500 human extrapulmonary tuberculosis cases annuallyβ€”80% attributed to animal sourcesβ€”the detection underscores the ongoing public health challenge of zoonotic transmission through contaminated meat and dairy products, in a context where half of cattle slaughter occurs outside official inspection channels.
