Tuberculosis (TB) vaccines are vaccinations intended for the prevention of tuberculosis. Immunotherapy as a defence against TB was first proposed in 1890 by Robert Koch . [ 1 ] As of 2021, the only effective tuberculosis vaccine in common use is the Bacillus Calmette-Guérin (BCG) vaccine, first used on humans in 1921.
A poster outlining precautions for airborne transmission in healthcare settings. It is intended to be posted outside rooms of patients with an infection that can spread through airborne transmission. [1] Video explainer on reducing airborne pathogen transmission indoors
Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
The COVID-19 virus has not been detected in drinking water. [82] Conventional water treatment (filtration and disinfection) inactivates or removes the virus. [82] COVID-19 virus RNA is found in untreated wastewater, [82] [22] [83] [a] but there is no evidence of COVID-19 transmission through exposure to untreated wastewater or sewerage systems ...
Effective TB treatment is difficult, due to the unusual structure and chemical composition of the mycobacterial cell wall, which hinders the entry of drugs and makes many antibiotics ineffective. [137] Active TB is best treated with combinations of several antibiotics to reduce the risk of the bacteria developing antibiotic resistance. [14]

airborne transmission – very small dry and wet particles that stay in the air for long periods of time allowing airborne contamination even after the departure of the host. Particle size < 5 μm. droplet transmission – small and usually wet particles that stay in the air for a short period of time. Contamination usually occurs in the ...
