DIMAPUR, NOVEMBER 21: Nagaland reported the highest spike of COVID-19 cases in a single week at 970 cases in the past week (November 14 to 20). The cases were fuelled by 4 super spreader events (SSE). The week also reported highest weekly positivity rate of 23% till date.
Super spreading events are where one person infects more people than on an average. Super-spreading relies on more than one person and it cannot happen in isolation. It takes a group of people that gather in such a way that increases the risk of transmitting the virus.
According to the COVID-19 weekly bulletin issued by the State Department of Health and Family Welfare, the past week recorded 4 super spreader events in the State – 2 in Government offices, 1 in District Jail and 1 in Post Office. All the 4 events have happened in crowded and closed settings.
“The 80/20 role in epidemiology states that 80% of cases come only from 20% of the infected and these 20% are responsible for explosive growth and sustained transmission,” it said.
On the super spreader events, the bulletin said 59 cases were reported from one Government office, 47 cases from a District Jail, 36 cases from another Government office and 21 cases from a Post Office – totaling 163 cases from the 4 super spreader events.
The weekly bulletin informed that COVID-19 transmission is slowly moving from younger age groups to high risk groups as more people with co-morbidities and older age groups are getting infected along with increase in symptomatic cases (5%). Four deaths were reported in the past week, and 50. 64% of all deaths in the State are below 60 years of age.
A major worry is that households and workplaces continue to be the most common places of COVID infection. Fever (78%) and cough (51%) are the most common reported symptoms in the State.
Among traced contacts, the most affected age group is 21-30 years at 26%, followed by 31-40 years at 25%. Among them, 63% are males.
Following younger age groups, there is a continuous increase in cases among 51-60 years age group in the past one week, and even in 60+ age category. Infection in the young follows later to the high-risk groups as is evident by the State data.
Positivity rate of 29% among household contacts and office goers 25% continues to be the highest. The positivity rate among students continues to remain steady at 18%. The positivity among symptomatic/pre-op screening/travel purposes coming to Flu clinics increased to 10%, which is worrisome, said the bulletin.
