Severe acute respiratory syndrome-Coronavirus 2 (SARS-CoV-2) is a novel virus from the family of coronaviruses which causes COVID-19 i.e. Coronavirus Disease-2019. It is the successor of the SARS-CoV-1 which caused the SARS outbreak in the year 2003-2004. This is a positive-sense single-stranded RNA virus which has rapid mutation properties.

The etymology of the name suggests that 'Corona' comes from the Latin word corōna meaning crown, garland, or a wreath. When seen under an Electron Microscope, the virion which has a diameter of 50-200 nanometres looks like the solar corona hence named Coronavirus.

When the virus enters the body; it attaches itself to the binding site or the ACE 2 receptors of healthy lung cells through its spike protein. Then it enters the cell via this attachment and causes apoptosis or cell death. The virus also affects organs other than lungs such as the brain, heart and kidneys. The multiple impact points make it problematic for the researchers to create a vaccine in addition to its rapid mutation properties.

The disease might have a zoonotic origin i.e. the transmission occurs from animals to humans. On comparing the genomic sequences the Human Coronavirus strain is found to be 96% identical to Bat Coronavirus samples and 92% similar to the Pangolins samples. Human transmission of the disease takes place via air droplets when the infected person is coughing, sneezing or talking.

The first cases of this respiratory illness were reported to the World Health Organization (WHO) from Wuhan City, Hubei Province, China, on 31 December 2019. It is the first severe outbreak since the 2009 H1N1 Influenza Pandemic. Initially, it was supposed that the site of origination is Huanan Seafood Wholesale Market but, in May 2020 the negative samples tested, by  Chinese Center for Disease Control and Prevention, from the livestock market suggested that it was the site of the super spreading of the virus.

SARS-CoV-2 is known to have an average reproduction number of 2.2-2.6 which means that, on an average, one infected person can spread the infection to 2-3 people. Although if measures like social distancing are put into use, to reduce the exposure of the infected population, it leads to a significant reduction in transmission rates. The infection fatality rate (IFR) of COVID-19 in various studies till 16th June 2020 was projected to range 0.60% to 1% of infected people . However few studies suggested the IFR as high as 3.6%.

The testing of an individual takes place through a method known as real-time Reverse transcription Polymerization Chain reaction (rRT-PCR). The process of obtaining strains and testing the patients usually involves nasal swabs or sputum swabs; the results come in within a span of a few hours to a couple of days.

Currently, there are no known vaccines available for the virus or any specific antiviral treatments, but there are numerous vaccines in works all over the world to tackle COVID-19. Experts believe that the minimum time required to test a vaccine is 12 to 18 months.

Trials are also going on for the repurposed drugs or the drugs which are useful for treating other diseases and might be capable against COVID-19: Some of these drugs are Hydroxychloroquine, chloroquine, Remdesivir, Dexamethasone, Lopinavir-ritonavir, and Convalescent plasma.

The only current solutions for tackling the pandemic are social distancing, hand wash, hygiene and face masks.

Black Lives Matter: Trump, Antifa, and the Anti-Racist movement

As massive protests following the passing of George Floyd kept on shaking the United States. President Donald Trump tweeted on 31st of May that far-left group Antifa was the one behind the violent riots and he would designate it as a terrorist group. He said, “The United States of America will be designating ANTIFA as a Terrorist Organization.” This assertion was repeated by the US Attorney General William Barr as well.

Antifa, short for anti-fascists, is an amorphous movement and not an organization as Trump labels it to be. They tend to be on the left of the U.S. political spectrum, many describing themselves as socialists, anarchists, anti-capitalists or communists. Antifa, according to many commentators, is just a decentralized collection of individual activists who mostly use non-violent methods to achieve their goal, which is to resist the spread of fascism. They track people who spread racist hatred and fascist ideology through on-ground events, traditional media, or social media and use cultural forms of art like drawing, music, film screenings etc. to spread the message of inclusivity. There are more militant anti-fascist groups as well, who mostly engage in non-militant activities but are willing to use more confrontational tactics at times as well. 

This is not the first time that Donald Trump has criticized Antifa to shift the focus away from racial discrimination faced by the black community in USA. In this instance as well President has tried to portray the protestors and looters with a vague phrase “radical-left bad people” and invoking “Antifa” to represent the whole of leftist militant groups which are bound more by belief than by any organizational structure.

Taking a cue from President Trump, many officials, conservative commentators and white supremacists started blaming Antifa for using the “Black Life Matters” movement to indulge in violence and undermining the government of the USA. Mr Trump’s national security adviser, Robert C. O’Brien, had also blamed such activists during his appearances on CNN and A.B.C. News. Mr O’Brien said the F.B.I. needed to “come up with a plan” to deal with Antifa. John Guandolo, who was in the FBI for 13 years, went a step ahead and claimed that Antifa and “Black Life Matters” are communist organizations, who are planning to overthrow the US government. He also praised President Trump for calling Antifa a terrorist organization and lamented that the FBI are unaware of its plan. Fiona Moriarty-McLaughlin, a journalist at the right-wing publication Washington Examiner, re-posted a video purportedly depicting "Paid #Antifa thugs" vandalizing the store — even though there is no evidence to suggest that the vandals were members of the movement.

The FBI and local law enforcement agencies have aggressively pursued charges against rioters, looters and others accused of havoc. However there is no evidence of any involvement of organized violence by Antifa or any other left-wing group. The most serious case that has emerged in federal court involved three men in Nevada linked to a loose, national network of far-right extremists advocating the overthrow of the U.S. government. They were arrested on May 30 on charges of trying to foment violence during Black Lives Matter protests. There are many instances when white thugs were seen vandalizing which blacks feared could be used against them.

The invocation of Antifa by President Trump during the “Black Life Matters” protest is conveniently used by the conservative commentators and white supremacists to somehow shift the focus away from the deep rooted racism in the USA to the violent actions by some protesters during the “Black Life Matter” protest.
