Murine Typhus

A 75-year-old man from Kerala who recently travelled to Vietnam and Cambodia diagnosed with the bacterial disease murine typhus.

  • Murine typhus is an infectious bacterial disease caused by the flea-borne bacteria Rickettsia typhi.
  • It is transmitted to humans through the bites of infected fleas.
  • The disease is also known as endemic typhus, flea-borne typhus or flea-borne spotted fever.
  • Host - Rodents like rats, mice and mongoose, are known to be reservoirs of the disease. The fleas can also live on other small mammals, including pets such as cats and dogs.
  • Once a flea is infected, it can spread the disease for the rest of its life.
  • Transmission - The disease is spread when infected flea faeces come into contact with cuts or scrapes in the skin.
  • Transmission can also happen through exposure of mucous membranes to infected flea faeces.
  • Murine typhus is not spread from one person to another, or from person to fleas.
  • Prevalent areas - The disease has been reported in coastal tropical and subtropical regions, where rats are prevalent.
  • In India, cases of murine typhus have been reported in the Northeast, Madhya Pradesh and Kashmir.
  • Symptoms - Usually appear 7 to 14 days after the exposure and include fever, headaches, body aches, joint pains, nausea, vomiting, and stomach aches.
  • Some people may later develop rashes on the skin, days after the initial symptoms.
  • The illness seldom lasts longer than two weeks, but may last for months with complications if not treated.
  • Treatment - There is no vaccine currently available against the disease.
  • The antibiotic doxycycline is considered effective in therapy, but early diagnosis is vital for treatment.
  • Fatality - Without timely treatment, the disease could turn severe in one or two weeks, and become fatal in rare cases.

Both Murine and Scrub Typhus share overlapping symptoms, while Scrub Typhus caused by Orientia tsutsugamushi is generally more severe and widespread in the Asia-Pacific region.

Dragon drones

Dragon drones have been used in the recent Russia-Ukraine War.

  • Dragon drones essentially release a substance called thermite, a mixture of aluminium and iron oxide.
    • Thermite is just one type of ‘incendiary weapon,’ with others including napalm and white phosphorous.
  • When ignited (usually with the help of an electrical fuse), thermite triggers a self-sustaining reaction that is quite difficult to extinguish.
  • These are known to emit a molten metal that burns at 2,427 degree Celsius (4,000 degrees Fahrenheit) and can even burn underwater.
  • As it comes down, the mixture resembles the fire spewed by the mythical dragon.
  • Discovered in – 1890s by a German Chemist and originally used to weld railway tracks.
  • On humans, it causes severe, possibly fatal, burns and bone damage.
  • There is little protection against thermite as it can burn through almost everything, including even metals.
  • Dragon drones tend to be low-flying because thermite is more effective when it’s in close contact with the target.
  • Under international law, thermite is not banned for military combat, but its use on civilian targets is prohibited.
