‘THREE QUASI-SUBSPECIES OF VIRUS IN CIRCULATION’

Focus: GS-III Science and Technology, Prelims

Why in news?

• A mixture of three quasi-subspecies of SARS-CoV-2 is in circulation in India, the Indian Council of Medical Research (ICMR) said on 31st March 2020.
• These imported variants showed no differences from how they behaved in the place of origin.
• Scientists are yet to classify a SARS-Cov-2 variant as an Indian strain.

Explanation

• India’s COVID-19 cases were mainly from people with travel history and their immediate contacts, which is to say that this virus was brought in from outside.
• ICMR is not seeing any variation from what is being seen on how this strain is behaving around the world. So there is no difference in its severity.
• However, in a large country like India, it’s difficult to predict an accurate trend about the progression of COVID-19 because we still don’t have enough time gap between the upswing of cases.
• The progression in terms of cases could not be compared with any other country as of now and people should be looking at the risk of exposure and adherence to physical distancing.
• Availability of testing kits was still an issue, and masks should not be used indiscriminately.
• India would be able to make indigenous diagnostic kits within the next month or two.

Virus and Strains of Viruses Explained

What is a virus?

A virus is a very simple thing — a coat of protein wrapped around some genetic code (DNA or RNA). It’s not a cell and it’s not living.

Hijacking a host cell

• A virus needs a host cell to be able to replicate itself. Once inside the host cell, it takes over.
• The cell is reprogrammed to produce the virus instead of doing what it was designed to do before.
• The virus is replicated thousands and thousands of times within that cell.
• Eventually, the cell bursts open and the multitude of viruses move around the body infecting other cells. This can happen within a few hours.

Mutation and Strains

• Mutation is when something changes as it is replicating. Viruses survive through mutation.
• This is a random act, rather than a deliberate act of survival.
• Some of the ways that viruses replicate are quite sloppy compared to the cells in our bodies.
• Our cells have special enzymes that make sure that a new cell has copied the gene sequence perfectly, but a virus is not so exact. The host cell (under instruction from the genetic material of the virus) produces thousands of copies of the virus, but they are often not going to be 100% exact.
• A slight mutation such as this with a virus means our immune system might not recognise it.
• That means the mutated virus copy can infect a new cell making another 50,000 copies of the new mutation without our immune system trying to stop it. The mutation results in a new strain of virus.
• You can have lots of strains (slight variations) of the same virus. Some viruses are sloppier than others when replicating and have many mutations. HIV (human immunodeficiency virus) is an example of this.

Reassortant strains

• Viruses like Influenza (flu) and rotavirus produce many different strains. They do this in a slightly different way from mutation.
• These viruses can make reassortant strains, meaning the strain is produced from the genetic material from two or more similar viruses.
• This happens when the gene material is chopped up in little pieces (rather than being in one long piece as with other viruses).
• Say you caught two different strains of the flu at once from two different people. A cell in your body could get infected with these two different strains. The strains can jumble up within the host cell and mix and match their little pieces of genetic material to create a new, dramatically different strain.
• This is how a flu pandemic occurs.
• The reassortant can spread quickly.
• Nobody’s immune system recognises the new virus strain so it is able to spread rapidly.

PRE-MONSOON CROP CULTIVATION TAKES A HIT

Focus: GS-III Disaster Management, Agriculture, Prelims

Why in news?

• Despite the State government being on overdrive to ensure that agricultural activities continue to be normal during this unprecedented crisis caused by COVID-19, officials are hopeful about pre-monsoon crop cultivation.
• Besides the main crops such as ragi and maize, farmers cultivate green gram, black gram and sesame, especially in Mysuru, Chamarajanagar, Mandya and Hassan districts, during this season.
• There is concern whether farmers will take up cultivation of these crops given the situation.

Details

• The preparatory work for sowing normally starts by the first week of April.
• In a few places, sowing has been completed, but it has not even commenced in many places.
• In agriculture timing, is very important. If sowing is delayed, it will hurt the yield and overall productivity.
• State Agriculture Department officials are appealing to farmers to continue with their agricultural activities while also staying safe.
• District administrations are working with dealers to ensure there is enough supply of seeds and fertilizers.
• Pre-monsoon crop contributes to less than 10% of the total agricultural production in the State, but remains important.
• The paddy in fields in Raichur, Ballari, Koppal and Gangavathi were ready for harvesting, but farmers were facing labour issues though the department has allowed them to get farm machineries for harvesting.

Background

Kharif Crops

• Kharif crops, monsoon crops or autumn crops are domesticated plants like rice that are cultivated and harvested in India,Bangladesh during the Indian subcontinent’s monsoon season, which lasts from June to November depending on the area.
• Kharif crops are usually sown with the beginning of the first rains during the advent of the south-west monsoon season, and they are harvested at the end of monsoon season (October-November).
• These crops are dependent on the quantity of rain water as well its timing.
• Too much, too little or rain at the wrong time may lay waste to the whole year’s efforts.
• Kharif crops stand in contrast to the rabi crops, which are cultivated during the dry season.

Kharif Season

• The kharif season varies by crop and region, starting at the earliest in May and ending at the latest in January. In India the season is popularly considered to start in June and to end in October.
• Monsoon rains may begin as early as May in some parts of the Indian subcontinent, and crops are generally harvested from 3rd Week of September to October, again depending upon the region and the crops. Rice,maize, sorghum and cotton are the major kharif crops in India.

Rabi Crops

• Rabi crops or rabi harvest are agricultural crops that are sown in winter and harvested in the spring in India and Pakistan.
• The opposite of rabi crops are the kharif crops which are grown after, the rabi and zaid (zaa-id) crops are harvested one after another respectively.

Rabi Season

• The rabi crops are sown around mid-November, preferably after the monsoon rains are over, and harvesting begins in April / May.
• The crops are grown either with rainwater that has percolated into the ground, or using irrigation.
• A good rain in winter spoils the rabi crops but is good for kharif crops.
• The major rabi crop in India is wheat, followed by barley, mustard, sesame, and peas.
• Peas are harvested early, as they are ready early: Indian markets are flooded with green peas from January to March, peaking in February.
• Many crops are cultivated in both Kharif and rabi seasons.
• The agriculture crops produced in India are seasonal in nature and highly dependent on these two monsoons.

SC UPHOLDS RIGHT TO DISCUSS COVID-19

Focus: GS-III Disaster Management

Why in news?

• The Supreme Court on 31st March 2020 upheld the right to free discussion about COVID-19, even as it directed the media to refer to and publish the official version of the developments in order to avoid inaccuracies and large-scale panic.
• It ordered the government to start a daily bulletin on COVID-19 developments through all media avenues in the next 24 hours.
• This was in response to a request from the Central government that media outlets, in the “larger interest of justice”, should only publish or telecast anything on COVID-19 after ascertaining the factual position from the government.

Arguments put forth by the Ministry of Home Affairs

• “Any deliberate or inaccurate” reporting by the media, particularly web portals, had a “serious and inevitable potential of causing panic in the larger section of the society”.
• Any panic reaction in the midst of an unprecedented situation based on such reporting would harm the entire nation. (Creating panic is also a criminal offense under the Disaster Management Act, 2005.)

Court’s Views

• In view of balancing free press and the need to avoid panic in society during an unprecedented crisis — The court said: “We expect the media [print, electronic or social] to maintain a strong sense of responsibility and ensure that unverified news capable of causing panic is not disseminated.”
• The court also recommended — A daily bulletin by the Government of India through all media avenues, including social media and forums to clear the doubts of people, would be made active within a period of 24 hours as submitted by the Solicitor- General of India.
• The court did not intend to interfere with the free discussion about the pandemic, but direct the media refer to and publish the official version about the developments.

Fake News issue

“Deliberate or inadvertent fake news and material capable of causing a serious panic in the minds of the public is found to be the single most unmanageable hindrance in the management of this challenge.”

What the Ministry of Home Affairs is going to do about it?

The Ministry of Home Affairs will set up a separate unit headed by a Joint Secretary-level officer in the Health Ministry and consisting of eminent specialist doctors from recognized institutions like AIIMS to answer the queries of citizens.

Other key highlights of the Report

• The mass migration of the poor would defeat the preventive measures taken by the Central government.
• There was no necessity for migrant workers to rush to their villages.
• The Centre, fully conscious that no citizen should be deprived of basic amenities, had announced a ₹1.70 lakh crore package under the Pradhan Mantri Garib Kalyan Yojana to take care of their daily needs. know more
