When will Covid-19 end?

Historically a pandemic has 3 types of ends. One, medical end which implies that the disease does not spread any more. Two, social end which happens when life returns to normal. And the last is political which is decided by the government.

 Obviously, it is the first kind that matters. And that end seems quite distant as of now. There is a lot of movement of people even now, including international journeys. That makes it a big challenge for medical science to contain the virus. People will have to acquire natural immunity to the virus if a medical end to the pandemic has to arrive. The vaccines are meant to bring about that immunity. Some may develop immunity by contracting the disease and overcoming it. A few may develop the immunity internally. There is also the possibility of the virus weakening due to various reasons and eventually disappearing.

Science has observed that the rate at which a pandemic moves towards its peak is the same as the rate of its decline. For example, if the doubling time of the spread (100 to 200 to 400 etc) is 20 days, the halving time (100 to 50 to 25 etc) will be 20 days too. Keeping that and the progress of the virus so far in mind, it is estimated that Covid-19 will beat a retreat only by the end of 2021 or the beginning of 2022.

Spanish Flu as an example

Look at the history of Spanish Flu in brief. It ravaged the world a century ago, in 1918-1920. Each wave lasted about 4 months.

1st Wave: Feb to June 1918

2nd Wave: Aug to Dec 1918

3rd Wave: Jan to April 1919

4th Wave: Dec 1919 to April 1920

The second wave was the deadliest killing millions of people all over the world. India witnessed the death of nearly 20 million people in that period. Bombay alone recorded 15,000 deaths when the population of the city was 1.1 million. The pandemic was known as Bombay Fever in India at that time.

The last wave hit after an interval of 8 months. In the meanwhile, the pandemic had affected 50 crore people and killed 5 crore. Spanish Flu affected only about half the countries in the world because international travels were not so common in those days. Those whom it killed were older than 40 mostly. But we should remember that the average lifespan in those days was 45. Most of the deaths were caused by pneumonia that followed the virus infection. We can see some similarities with Covid-19.

Because of improved health conditions, the most risky group hit by Covid-19 seems to be those above 60 years old. But the virus has done much harm to youngsters too. No one can afford to take risks though the second wave seems to be receding.

PS. Did this virus come as a result of what we did to the planet and the environment? Or did China create it in a lab? You can read about China’s role here: The Evil Empire: Is China on its way to world domination?

PPS. The above post is based largely on an article I read in a Malayalam weekly, Madhyamam, written by Dr Jayakrishnan T.

    Indeed, I beleive there is still quite a way to go before we reach anything like the 'normality' of not having to worry about whether each person we meet has potential to pass on this serious illness to us. I avoid subscribing to conspiracy theories - but the fact that WHO is investigating so thoroughly the possible lab escape suggests the 'no smoke without fire' aspect... oh to be a fly on the historian's wall a hundred years hence.

    1. Given China's track record, this possibility cannot be ruled out. Xi thinks he's performing a divine task.

  2. The way the virus is mutating my guess its not natural, cannot rule out the china angle, but it is now no use of blaming anyone. Its in our backyard and we have take care of it by ourselves, yesterday received a message from my friend who is doctor, listing how many doctors we have lost to the virus only in Karnataka its staggering....have lost many relatives to this virus in 1st wave and 2nd wave. Hope to see some sense in the people and follow safety regulation given the government and vaccinate themselves before the virus taps on your door :-) Since seen the roll coaster from the front seat...would not advise this ride for any body !

The Ghost of a Banyan Tree

  Image from here Fiction Jaichander Varma could not sleep. It was past midnight and the world outside Jaichander Varma’s room was fairly quiet because he lived sufficiently far away from the city. Though that entailed a tedious journey to his work and back, Mr Varma was happy with his residence because it afforded him the luxury of peaceful and pure air. The city is good, no doubt. Especially after Mr Modi became the Prime Minister, the city was the best place with so much vikas. ‘Where’s vikas?’ Someone asked Mr Varma once. Mr Varma was offended. ‘You’re a bloody antinational mussalman who should be living in Pakistan ya kabristan,’ Mr Varma told him bluntly. Mr Varma was a proud Indian which means he was a Hindu Brahmin. He believed that all others – that is, non-Brahmins – should go to their respective countries of belonging. All Muslims should go to Pakistan and Christians to Rome (or is it Italy? Whatever. Get out of Bharat Mata, that’s all.) The lower caste Hindus co...

Tanishq and the Patriots

Patriots are a queer lot. You don’t know what all things can make them pick up the gun. Only one thing is certain apparently: the gun for anything. When the neighbouring country behaves like a hoard of bandicoots digging into our national borders, we will naturally take up the gun. But nowadays we choose to redraw certain lines on the map and then proclaim that not an inch of land has been lost. On the other hand, when a jewellery company brings out an ad promoting harmony between the majority and the minority populations, our patriots take up the gun. And shoot down the ad. Those who promote communal harmony are traitors in India today. The sacred duty of the genuine Indian patriot is to hate certain communities, rape their women, plunder their land, deny them education and other fundamental rights and basic requirements. Tanishq withdrew the ad that sought to promote communal harmony. The patriot’s gun won. Aapka Bharat Mahan. In the novel Black Hole which I’m writing there is...

The Adventures of Toto as a comic strip

  'The Adventures of Toto' is an amusing story by Ruskin Bond. It is prescribed as a lesson in CBSE's English course for class 9. Maggie asked her students to do a project on some of the lessons and Femi George's work is what I would like to present here. Femi converted the story into a beautiful comic strip. Her work will speak for itself and let me present it below.  Femi George Student of Carmel Public School, Vazhakulam, Kerala Similar post: The Little Girl

The Circus called Politics

Illustration by ChatGPT I have/had many students whose parents are teachers in schools run or aided by the government. These teachers don’t send their own children to their own schools where education is free. They send their children to private schools like the one where I’ve been working. They pay huge fees to teach their children in schools where teachers are paid half of or less than their salaries. This is one of the many ironies about the Kerala society. An article in yesterday’s The Hindu [ A deeper meaning of declining school enrolment ] takes an insightful look at some of the glaring social issues in Kerala’s educational system. One such issue is the rapidly declining student enrolment in government and aided schools in the state. The private schools in the state, on the other hand, are getting more students. People don’t want to send their children to the schools run by the government systems. The chief reason is that the medium of instruction is Malayalam. The second ...

The Harpist by the River

Preface One of the songs that has haunted me all along is By the Rivers of Babylon by Boney M [1978]. It is inspired by the biblical Psalm 137. The Psalm was written after the Babylonian King, Nebuchadnezzar II, conquered the kingdom of Judah and destroyed their most sacred temple in Jerusalem. The Jews were soon exiled to Babylon. Then some Babylonians asked the Jews to sing songs for them. Psalm 137 is a response to that: “How can we sing the Lord’s song in an alien land?” There is profound sorrow in the psalm. Exile and longing for homeland, oppression by enemies, and loss of identity are dominant themes. Boney M succeeded in carrying all those deep emotions and pain in their verses too. As I was wondering what to write for today’s #WriteAPageADay challenge, Boney M’s version of Psalm 137 wafted into my consciousness from the darkness and silence outside my bedroom long before daybreak. How to make it make sense to a reader of today who may know nothing about the Jewish exile ...
