AHMEDABAD: While vaccination for Covid-19 began in January of this year, the case after the first positive rate is relatively low due to a lower rate of vaccination.
Factors resulting in relatively lower seropositivity, which is not enough to derail a second wave recorded a huge spike in daily cases, claims a new study recently published.
On the other hand, more seroprevalence result in infections which is comparatively lower in the second wave, the study claims ‘COVID-19 infection at 8 Big Cities of India: Dynamics Distribution and seropositive’ published in the European Journal of Medical and Health Sciences.
The authors included experts from India, Japan, United Kingdom and United States.
This study took the data from seroprevalence of the pathology lab private to eight cities – Ahmedabad, Bangalore, Coimbatore, Jaipur, Nagpur, Pune, Surat and Vishakhapatnam – and extrapolated to daily data Covid-19 case for the cities of the same during the second wave to see the impact of seropositivity in the number of cases.
‘In July 2020, 683 new cases per million note …
the peak was reported in 8431 cases per million.
In June 2021, the lowest monthly at 284 cases per million were registered.
Seroprevalence in 48.4% of the population is not enough to stop the second wave of the pandemic as a large number of cases registered in March and continued until May 2021, “the paper noted.
Surat, studies say that the city recorded a relatively lower case in 6647 per million in April 2021.
In June, it dropped to 306 per million.
higher prevalence (32%) in July compared to other cities, he added.
A task force Covid member states, while assessing the figures, said the findings come with a warning.
“Methodology to mention that it was not a random sampling – patients who come specifically to Covid or other related diseases tests assessed.
It may not give a true picture of a given population, “stated the member.
“Nonetheless, it should be taken as an indicator for the need to achieve higher vaccination to reduce new cases.”
