BF.7
D)
BH.9

Correct Answer :   BF.7

The current surge in Covid-19 infections in China is believed to be driven by the BF.7 sub-variant of Omicron that is circulating in that country.

This isn’t the first time that BF.7 has made news — in October 2022, it started to replace the variants that were then dominant in the United States and several European countries.
 
When viruses mutate, they create lineages and sub-lineages — like the main trunk of the SARS-CoV-2 tree sprouting branches and sub-branches. The BF.7 is the same as BA.5.2.1.7, which is a sub-lineage of the Omicron sub-lineage BA.5.
 
A study published in ‘Cell Host and Microbe’ journal earlier this month reported that the BF.7 sub-variant has a 4.4-fold higher neutralisation resistance than the original D614G variant — meaning that in a lab setting, antibodies from a vaccinated or infected individual were less likely to destroy BF.7 than the original Wuhan virus that spread worldwide in 2020.
 
But BF.7 is not the most resilient sub-variant — the same study reported a more than 10-fold higher neutralisation resistance in another Omicron sub-variant called BQ.1..

Correct Answer :   Russia

French scientists have revived a 48,500-year-old “zombie virus” buried under a frozen lake in Russia.
 
* According to New York Post, the French scientists have sparked fears of yet another pandemic after the revival of the zombie virus.
 
* The New York Post has quoted a viral study which is yet to be peer-reviewed. "The situation would be much more disastrous in the case of plant, animal, or human diseases caused by the revival of an ancient unknown virus," reads the study.
 
* According to the preliminary report, global warming is irrevocably thawing enormous swathes of permafrost -- permanently frozen ground that covers a quarter of the Northern Hemisphere. This has had the unsettling effect of "releasing organic materials frozen for up to a million years" - possibly deadly germs included.
 
* The oldest, Pandoravirus yedoma, was 48,500-year-old, a record age for a frozen virus returning to a form where it may infect other creatures. This breaks the previous record of a 30,000-year-old virus identified in Siberia by the same scientists in 2013.
 
* The new strain is one of 13 viruses described in the study, each with its own genome, according to Science Alert.
 
* While the Pandoravirus was discovered at the bottom of a lake in Yukechi Alas, Yakutia, Russia, others have been discovered everywhere from mammoth fur to Siberian wolf intestines..

Correct Answer :   Mpox

Monkeypox will now be known as mpox, the World Health Organization (WHO) said on Monday(28th Nov 2022), in the wake of reports of racist and stigmatizing language surrounding the name of the disease. 
 
* The decision follows a series of consultations with global experts. 
 
* Both terms will be used simultaneously for a year before the monkeypox name is phased out. 
 
* “This serves to mitigate the concerns raised by experts about confusion caused by a name change in the midst of a global outbreak”. 
 
 
Concern and change :
* Mpox is a rare viral disease that primarily occurs in tropical rainforest areas of Central and West Africa, but outbreaks emerged in other parts of the world this year.   
 
* There have more than 80,000 cases, and 55 deaths, with 110 countries affected
 
* When the current outbreak expanded, WHO both observed and received reports of racist and stigmatizing language online, in other settings and in some communities. 
 
* “In several meetings, public and private, a number of individuals and countries raised concerns and asked WHO to propose a way forward to change the name,”
 
Naming new diseases :
* The monkeypox name was given in 1970, some 12 years after the virus that causes the disease was discovered in captive monkeys. 
 
* This was before WHO first published best practices on naming diseases in 2015. 
 
* These guidelines recommend that new disease names should aim to minimize unnecessary negative impacts on trade, travel, tourism or animal welfare. 
 
* They should also avoid offending any cultural, social, national, regional, professional or ethnic groups.

The Drugs Controller General of India (DCGI) on Tuesday(6th September 2022) approved the country’s first intra-nasal Covid-19 vaccine -- Bharat Biotech’s iNCOVACC -- for restricted emergency use in those aged above 18 years.

It’s only the second such vaccine in the world, after CanSino Biologics’ vaccine in China, to get regulatory approval. Around 100 mucosal (nose and mouth) Covid-19 vaccines are under development across the world.
 
iNCOVACC is a chimpanzee adenovirus vectored recombinant nasal vaccine that has been specifically formulated to allow intra-nasal delivery through nasal drops. The nasal delivery system has been designed and developed to be cost effective in low- and middle-income countries, the company said. The vaccine is stable at 2-8°C.
 
Union Health Minister "Mansukh Mandaviya" said the vaccine has been approved for “primary immunisation against Covid-19 in the 18+ age group for restricted use in emergency situation”..

Correct Answer :   European Commission

Danish biotechnology company Bavarian Nordic said on Monday(25th July 2022) the European Commission had given permission for its Imvanex vaccine to be marketed as protection against monkeypox, as recommended last week by the European Medicines Agency (EMA). Globally, over 16,000 cases of monkeypox have been reported from 75 countries.
 
In the current outbreak in countries and amongst the reported monkeypox cases, transmission appears to be occurring primarily through close physical contact, including sexual contact. Transmission can also occur from contaminated materials such as linens, bedding, electronics, and clothing, that have infectious skin particles.
 
Imvanex is a non-replicating smallpox vaccine developed in collaboration with the U.S. government to ensure the supply of a smallpox vaccine for the entire population, including immunocompromised individuals.
 
The vaccine gained regulatory approvals in Canada (marketed as Imvamune) and the U.S. (marketed as Jynneos) where the approvals have been extended to include the monkeypox indication as the only vaccine obtained this to-date.
 
The vaccine was approved by the European Commission in 2013 for immunization against smallpox in adults aged 18 years and older.
 
Imvanex can be used as active immunisation against smallpox, monkeypox and disease caused by the vaccinia virus in adults..

Ghana, a country in West Africa, has officially confirmed two cases of the deadly Marburg virus. The two patients, both deceased, tested positive for the highly infectious virus in the southern Ashanti region of Ghana. The World Health Organization (WHO) confirmed the same in a statement on July 17, 2022. The two Malburg cases in Ghana were unrelated.

Marburg is a highly infectious viral hemorrhagic fever, which belongs to the same family as the Ebola virus disease and has a fatality ratio of up to 88 percent. Marburg virus symptoms include high fever, severe headache and malaise.

On June 9th 2022, Agriculture Minister Narendra Singh Tomar launched Anocovax, India's first homegrown COVID-19 vaccine for animals, produced by the ICAR-National Research Centre on Equines (NRCE) in Haryana. The vaccine uses Alhydrogel as an adjuvant and contains inactivated SARS-CoV-2 (Delta) antigen. It is also safe for dogs, lions, leopards, mice, and bunnies, according to the company.
 
Anocovax is a SARS-CoV-2 Delta (COVID-19) vaccine for animals that is inactivated. According to the Indian Council of Agricultural Research (ICAR), the immunity elicited by Anocovax neutralises both the Delta and Omicron versions of SARS-CoV-2..
