In which country were polio cases recorded after 30 years for the first time?
  • China
  • Australia
  • Iran
  • Burundi
Answer- D
Burundi recently recorded its first cases of polio in 30 years. The presence of Poliovirus type 2 was confirmed through the analysis of wastewater from the region.

Polio is typically transmitted through contact with contaminated water or food, or by coming into contact with an infected person. While many people do not experience severe symptoms, some can develop acute flaccid paralysis.
