The Delta variant of Corona virus is termed as Variant of Concern (VoC) by the officials of the Union Health Ministry on 22nd June, 2021. It must be noted that the officials also said that this Delta variant is also the Variant of Interest (VoI).
DELTA VARIANT | DELTA PLUS VARIANT OF INDIA
The Delta variant of Coronavirus is the most spread variant of the Corona virus in India. The Delta variant is also having a lot of varieties due to the different mutations present on their protein covering.
Around 80 countries of the world have detected the delta variant of coronavirus. It must be noted that it was first found in December 2020 in India and it triggered the second COVID wave which had devastating effects.
It must be noted that the recent Delta plus variant, which is recently found in three states, is becoming a matter of concern for India and the world as it has the new additional mutation called K417N.
Due to this mutation it is called Delta plus variant of coronavirus. Previously this variant was found in different countries. This additional mutation K417N allows the virus to escape from the antibodies created by the vaccines.
K417N was identified in the Beta variant which was found in South Africa as well as in the Gamma variant of Brazil. It must be noted that these variants which were having the K417N mutation were able to decrease the strength of the vaccines and they are more infectious than those non-additional mutation variants.
Delta variant of Coronavirus is also called AY1 or B.1.617.2.1. Delta plus is a variant of the Delta (B.1.617.2) with the additional mutation of the K417N.
DELTA PLUS VARIANT IN INDIA
The Union Health Ministry on Tuesday announced that there are 22 confirmed cases of the Delta Plus variant in the Country. It must be noted that out of 22 cases, 16 cases belong to Madhya Pradesh, Maharashtra and Kerala.
The officials informed the health secretaries of this state that these cases are from the Jalgaon, Ratnagiri district of Maharashtra, Palakkad and Pathanamthitta districts of Kerala, and Bhopal and Shivpuri district of Madhya Pradesh.
The official of the Union Health Ministry has informed the concerned health secretaries of each state to take the measures in order to curb these most infectious variants of the Delta variant.
“The states’ chief secretaries have been advised to take up immediate containment measures in the districts and clusters (as identified by INSACOG) including preventing crowds and intermingling of people, conduct widespread testing, prompt tracing as well as vaccine coverage on a priority basis,” the health ministry said in a press release.
“They were also advised to ensure that adequate samples of positive persons are promptly sent to the designated laboratories of INSACOG so that clinical epidemiological correlations can be made for further guidance to be provided to the states,” the release further added.
According to a TheHindu, a four year old was infected from this delta plus variant from Kadapra in Pathanamthitta District of Kerala. The child has been recovered as he was tested positive on 24 May. It was found by genome sequencing done by the CSIR-IGIB in New Delhi.
Till now more than 40 Delta plus variants are present in the country. According to the Maharashtra Health Minister Rajesh Tope, the number of delta plus variant cases in Maharashtra is 21.
Health Minister Rajesh Tope said of the 21 cases, nine were found in Ratnagiri, seven in Jalgaon, two in Mumbai and one each in Palghar, Sindhudurg and Thane.
DELTA PLUS VARIANT IT’S DANGER AND ITS SYMPTOMS
Due to the K417N mutation, this virus is able to reduce the impact of vaccines in patients. Meanwhile, it is also able to decrease the amount of antibodies produced by the vaccines.
This is confirmed by the tests performed in the countries where this mutation was previously found. It must be noted that this mutation is reducing the amount of antibodies produced as compared to the previous delta variant.
It means the amount of antibodies produced due to vaccines in previous delta variants (without K417N mutation) were higher than those who are having K417N mutation in the Gamma and the Betta variant of Brazil and South Africa respectively.
The main point over here is that this virus is also more infectious and it might increase the extent of the Third COVID wave. In this third covid wave the children who are usually not vaccinated will be the most vulnerable part of the country.
According to the Gavi Vaccine Alliance, the Delta variant is making patients become sicker and their condition deteriorates faster than in cases of infections caused by previous variants.
According to the Gavi alliance, progression of symptoms in Delta variant infection cases goes like this: headache, followed by sore throat, a runny nose, and fever. Cough is less common and loss of smell is also not common.
From all these symptoms it is making a cluster of symptoms as sore throat is not a symptom that was initially associated with the COVID-19 infections.
