J’khand heading towards herd immunity: Experts
If the findings of the national sero survey are to be believed, Jharkhand might develop herd immunity ahead of a possible third wave. As per the fourth national sero survey for SARS-Cov-2 released by the Indian Council of Medical Research (ICMR), the general population in the state showed IgG positivity (anti S1-RBD antibodies) to the tune of 55.3% while it touched 80.43% among health workers.
As per the document released by ICMR, a total of 1,231 persons were tested for antibodies across three districts from the general population, of which 680 showed the presence of antibodies. While among health workers, 302 persons were tested and 243 had antibodies.
The three districts that were selected for the survey are Pakur, Latehar and Simdega. In the general population category, Simdega topped the chart with 65.3% of those surveyed having antibodies while Latehar reported 56.6% and Pakur 44%. In the health worker category, 85% in Latehar have developed antibodies followed by Simdega with 81%, while Pakur reported 77%.
First Human Case of Monkey B Virus
China has reported the 1st human infection case with the Monkey B virus (BV). Monkey B virus is an alphaherpesvirus enzootic (endemic) in macaques, and it was initially isolated in 1932.
Alphaherpesviruses are pathogens or neuroinvasive viruses that establish lifelong infections in the peripheral nervous system of humans and many other vertebrates.
B virus is commonly referred to as herpes B, herpes virus simiae, and herpesvirus B.
B virus can survive for hours on surfaces, exceptionally when moist.
Updation of Motto of the Olympics
The Motto of Olympics was updated to Faster, Higher, Stronger – Together from Faster, Higher, Stronger, on 20th July 2021. Motto updation was done to show solidarity around the globe at the time of the Covid-19 pandemic. The International Olympic Committee (IOC) has approved the change.
The Olympic motto was Citius, Altius, Fortius (in Latin) or Faster, Higher, Stronger (in English), from 1894, when it was adopted at the suggestion of Pierre de Coubertin, founder of the IOC (International Olympic Committee).
Citius, Altius, Fortius, Communiter is the Latin version of the new motto.
Ski mountaineering was approved as an extra sport for the Milan-Cortina Winter Games which is to be in 2026. Ski mountaineering sport involves climbing mountains either by carrying the skies or on them and then descending on skies. Ski mountaineering is a prevalent sport in Italy. Five medal events for this category were planned at the 2026 Games.
New Generation of Akash Surface-to-Air missile
The DRDO successfully flight-tested a new generation of Akash surface-to-air missiles from an integrated test range off the coast of Odisha, enhancing air defence capabilities. Compared with the original version, the new variant of Akash-NG has a slightly better range and can strike targets at a distance of about 25 kilometers. During testing, the missile demonstrated the high manoeuvrability required to eliminate rapid and agile aerial threats.
Akash is India’s first indigenously manufactured medium-range Surface-to-Air missile capable of engaging multiple targets from multiple directions.
It is capable of being launched from mobile platforms such as battle tanks or wheeled trucks. It has a kill probability of nearly 90%.
The missile is aided by an indigenously developed radar known as ‘Rajendra,’ which is capable of handling multiple targets from multiple directions in group or autonomous mode.
Indigenously Developed MPATGM for Minimum Range
In a major push for AatmaNirbhar Bharat and the strengthening of the Indian army, DRDO successfully conducted flight tests on the indigenously developed low-weight, firepower and forget Man Portable Anti-Tank Guided Missile (MPATGM).
The test successfully validated the minimum range.
The maximum range of the missile has already been successfully flight tested.
The missile is equipped with the most advanced miniature infrared imaging seeker and advanced avionics.
The test made the development of an indigenous third-generation MPATGM nearly completed.
Sero Survey – Population Affected by Covid
Antibodies against the coronavirus are present in two-thirds of India’s population. 67.6 percent of adults were seropositive, and more than 62 percent were unvaccinated. Around 400 million of India’s 1.4 billion people do not have antibodies
About the Sero Survey:
? Sero studies are often called sero surveys, which check how many people in the population are infected with COVID-19.
The sero survey roughly shows the following points:
? The percentage (%) of the population that has been infected with the virus.
? Which groups have more exposure or higher infection rates
? The progress of the infection rate in a specific area.
? How close are we to herd immunity
