‘STEP UP CHECKING IN PATIENTS’; COMMUNITY TRANSMISSION IN INDORE?; MIDDLE-AGE MORTALITY
April 10, 2020
At a time when hotspot
containment measures are among the focus areas for prevention and control
of the coronavirus outbreak (COVID-19), renowned virologist T. Jacob John
has called for a shift in strategy — chasing the virus should be phased
down and checking the virus in infected persons should be stepped up.
As most COVID-19 patients in Indore, where 17 persons tested
positive on 31st March 2020, have no contact or travel history, health workers are
grappling to identify the source, indicating the most populous and largest
city of Madhya Pradesh MAY already be witnessing the community
Middle-aged people, and not
just the elderly, have a dramatically higher risk of dying or developing
serious illness from coronavirus (COVID-19), says a study.
Containment and Testing for the virus: Virologist’s views
Healthcare checking is
another way of containment measure as we will be finding infected people
who had no travel history.
We do not see it because the
majority of people are silently infected and only a few will show
We are not looking at
symptomatic people. We are looking at test results, tests based on travel
and contact with those who have travelled. That phase is more or less
Continuing to chase people
who had travelled and their contacts is alright if we have sufficient
manpower and energy.
But today, what we need to
understand is that the virus has widely spread.
Anybody with fever and cough
must be checked. Additional symptoms like fatigue, headache, nausea,
vomiting, diarrhoea, body ache are common to both influenza and COVID-19.
High fever is common in
COVID-19 but not in common cold. So, influenza and COVID-19 should be in
one category, and all other respiratory infections in another.
Community Transmission in Indore?
According to the World Health
Organisation (WHO), community transmission is evidenced by the inability
to relate confirmed cases through chains of transmission for a large
number of cases, or by increasing positive tests through sentinel samples.
Indore bears the burden of 44
patients, most residents of congested localities, of the 66 cases in the
Coincidently almost all
positive cases, including first ones, have come from congested areas, so
probably they have done a lot of community transmission.
COVID-19 mortality risk
It was found in a study that
age was a key determining factor in serious infections, with nearly one in
five over-80s requiring hospitalisation, compared to around 1% among
people under 30.
Taking into account estimates
of the number of cases that may not have been clinically confirmed — that
is, mild or asymptomatic infections — the data showed the hospitalisation
rate of patients in their fifties was 8.2%.
Analysis very clearly shows
that at aged 50 and over, hospitalisation is much more likely than in
those under 50, and a greater proportion of cases are likely to be fatal.
