Has
corona COVID 19 established in South Korea due to a super spreader?

South Korea has a population of 5 crore with 24.7 lakh
in city of Daegu which is facing an “unprecedented
crisis” after coronavirus infections that centred on the “cult” church surged
to 38 cases, out of country’s total 104.
The city, which is two hours south of the
capital Seoul, was turned into a ghost town after health officials said the
bulk of country’s 31 new cases announced on Thursday were linked to a branch of
the Shincheonji Church of Jesus.
About
1,000 members attended worship at the church. 1,001 members of the church are asked to self-isolate to
contain the spread of the virus.
The Diamond Princess
has shown us that 21% get infected if people stay together.
Super-Spreader
South
Korea's CDC has described an outbreak of coronavirus infections linked to a church
in the city of Daegu as a "super-spreading event".
WHO says it
does not use "super-spreading" as a technical term. However, "there
can be incidents of transmission where a large number of people can become
infected from a common source".
The term
"super-spreader" implies that a particular person may be inherently
more able than others to pass on disease, but virus experts say there is no
evidence to show that is the case.
The spread of a virus like the new coronavirus
depends on a range of environmental and epidemiological factors that ultimately
lead to transmission in individual cases or clusters. These include the patient
and what stage of disease they are in, their behaviour, their environment, and
the amount of time spent in that environment.
The WHO
described the South Korea outbreak as a "cluster" of cases and not super-spreading.
