Melioidosis is a serious bacterial infection caused by *Burkholderia pseudomallei*, found in contaminated soil and water. It primarily affects people and animals in tropical and subtropical regions, notably Southeast Asia and Northern Australia. The disease can manifest in various forms, from localized skin infections to severe pneumonia, blood poisoning, or chronic abscesses.

Melioidosis was first identified in 1912 by Alfred Whitmore and C.S. Krishnaswami in Rangoon, Burma (now Yangon, Myanmar). It gained historical significance during the Vietnam War, where it was nicknamed the 'Vietnamese time bomb' due to its ability to remain dormant for years before causing illness. Recognition of its widespread endemicity and diverse clinical manifestations has grown substantially over time.
Melioidosis is primarily transmitted through direct contact with contaminated soil and water, typically via inoculation through skin cuts or abrasions. Inhalation of contaminated dust or water droplets, and ingestion of contaminated water, are also possible routes of infection. Person-to-person transmission is extremely rare.
Contagious Period: Varies by disease
