Question 1 of 10
1. Question
Passage 1:
A study published in Nature Medicine suggests that antibodies formed against SARS-CoV-2 begin to decrease in number, just two-three months after infection. “We observed that IgG levels and neutralizing antibodies in a high proportion of individuals who recovered from SARS-CoV-2 infection start to decrease within two-three months after infection,” Quan-Xin Long from Chongqing Medical University, Chongqing, China and others write.
(2)In contrast, circulating antibodies against 2002-2003 SARS and MERS coronavirus were found to last more than one year. In the case of the 2002 SARS, sustained IgG levels were seen for more than two years after infection, while antibody response lasted for nearly three years in the case of MERS.
(3)This does not necessarily mean that people previously infected with SARS-CoV-2 can be reinfected soon after. Even if the antibody level decreases, it might be protective. “A person with low antibody level can get reinfected but the viral load will be low, infectivity will be less and he/she may not progress to a diseased state,” says virologist Jacob John formerly with CMC Vellore. “Antibodies specific to a virus even when present in low levels will be protective against disease.”
(4) Besides inducing neutralising antibodies, novel coronavirus has also been found to induce cellular immunity. As a result, the immune system’s T cells and B cells are elevated in an infected person. “Generally, when antibody levels are high, the T cells are low and vice versa,” says Dr. John.
(5)When infected by a virus, non-specific immune response in the form of macrophages, neutrophils and other cells tend to prevent the virus from causing symptoms. Soon after, the body makes antibodies specific to the virus called the immunoglobulins — IgG and IgM, called the adaptive response. In addition, the cellular immunity kicks in when the body makes T cells that destroy cells that have been infected by the virus. The combination of adaptive response and cellular immunity “may prevent progression to severe illness or re-infection by the same virus. This process is often measured by the presence of antibodies in blood,” WHO says.

Question 6 of 10
6. Question
Passage 2:
During these days of lockdown across various parts of India, we see reports of ‘wild’ animals coming over to the cities, towns and urban clusters. In Uttarakhand, an elephant was reported to come down unusually near Hari ki Pauri in Haridwar. A leopard was sighted in Almora. In Karnataka, elephants, spotted deer and sambar deer had transgressed into towns, while in Maharashtra, people spotted scores of civet cats, mongooses and porcupines in communities. All these ‘trespasses’ have been happening not only in India but across the world, wherever lockdowns took place and regular human activities have been curtailed. Once these lockdowns are lifted, animals are expected to retire back to their wild environment – wherever and however limited they are.
To get a perspective of this, note that of the total land area of the world, which is about 510 million square km, 30% is desert and 24% mountainous, leaving us humans to occupy about 45-50% of the remaining area when we started to live as communities about 17,000 years ago. (Prior to that, humans lived in the wild, along with animals and plants, as hunter gatherers). And over these millennia, particularly during the present one, we have built cities and urban clusters, thus making what was ‘wild’ land into ‘civilised’ land. (Note, too, that even today, adivasis and tribals still live in the wild, along with the local animals and plants). Indeed, geo-zoologists have argued that it is we humans who have transgressed and changed the landscape of Mother Earth.
Incidentally, this appears to be true of not only on land, but in water as well. BBC news reported how with a lull in traffic in the Bosphorus marine route during lockdown in Istanbul, dolphins are increasingly sighted near the shores of the city. Likewise, as the Ganga became less polluted in recent days due to decreased industrial and human waste during lockdown, the Ganges dolphins and gharials (fish-eating crocodiles) have been sighted in larger numbers. In mountains, too; Marco Lambertini of the World Wildlife Fund is concerned that COVID-19 could infect mountain gorillas which are likely to be particularly vulnerable as they share about 98% of their DNA with humans. They, like all great apes, are already endangered due to habitat loss, poaching and diseases – only 900 remain in the mountains of Central Africa.
