Poliomyelitis
  • Poliomyelitis is a highly infectious viral disease, mainly affecting children. According to WHO, the virus is transmitted from person-to-person, mainly through the faecal-oral route.
  • There are three types of polio virus strains – P1, P2 and P3.
  • P2 was eradicated globally in 1999. India attained a polio free status in 2014 after successfully eliminating the wild P1 and P3 strains.
  • The vaccine used by the world health organisation (WHO) in the global eradication effort is a trivalent preparation comprising all three serotypes.

  • BSE, which is trying to create a niche in the segment dominated by Multi Commodity exchange of India, started offering delivery based future contact in gold and silver.
Post Office in India

Vertical’ Earthquakes
  • Catastrophic tsunamis are often triggered by ‘megathrust earthquakes’, which occur at subduction zones when one tectonic plate is forced under another, causing massive chunks of the earth’s crust to move vertically. 
  • Such movements on the ocean’s floor cause huge volumes of water to be displaced suddenly, and throw up giant waves that can travel very fast across great distances.
Horizontal’ Earthquakes
 
  • Horizontal Earthquake is called a ‘strike-slip fault’, in which the earth’s movement is largely horizontal. 
  • This would not normally trigger a tsunami — however, it is possible for a strike-slip fault to also have some amount of vertical motion that could displace water.
