Yellow dust

Date: 25 October 2020 Tags: Miscellaneous


North Korean authorities have urged citizens to remain indoors to avoid contact with a mysterious cloud of ‘yellow dust’ blowing in from China, which they have warned could bring Covid-19 with it.


North Korea claims it has had no cases of the novel coronavirus, but imposed strict border closures and restrictions on movement of people as early as January.



  • During a weather segment, the state-controlled Korean Central Television (KCTV) warned that a cloud of yellow dust would blow in from China and descend on the country the following day.

  • A nationwide ban on outdoor construction work was announced, and all citizens were ordered to remain indoors with their windows tightly closed.

  • An article in the newspaper argued that since research from around the world has shown Covid-19 can be “transmitted through air”, the yellow dust cloud must be taken seriously.

  • Yellow dust is actually sand from deserts in China and Mongolia that high speed surface winds carry into both North and South Korea during specific periods every year.

  • The sand particles tend to mix with other toxic substances such as industrial pollutants, as a result of which the ‘yellow dust’ is known to cause a number of respiratory ailments.

  • Usually, when the dust reaches unhealthy levels in the atmosphere, authorities urge people to remain indoors and limit physical activity, particularly heavy exercise and sport.

  • Sometimes, when the concentration of yellow dust in the atmosphere crosses around 800 micrograms/cubic meter, schools are shut and outdoor events cancelled in the affected areas.

  • While researchers say the virus can remain airborne for hours, it has also maintained that it is highly unlikely for the Covid-19 infection to spread in this way, particularly outdoors.

  • People are most likely to contract the disease by standing in close proximity to an infected person who coughs, sneezes or talks, thus spreading the virus through droplets.
