The lockdown phase of COVID-19 has brought into our knowledge many inventions that can protect
and guard us against this deadly virus.
Mention at least three such inventions and their significance in our protection. Give detailed
information about the protective measures along with illustration wherever possible

Answer:
A lockdown cannot be imposed on a whim or gut feeling. Crucially, it should never be imposed to garner approval ratings. There has to be a science behind it; the decision must be evidence based, not a reflection of a house constructed from sand. The lockdown in India, now all set to enter its fourth stage, is laughable. It was imposed from March 25. As per the WHO, there had been a total of 434 cases till that day, with a cumulative 9 deaths. Italy had 63,927 cases with 6077 deaths, and the US had 42,164 cases and 571 deaths.
It is now May 17 and India has seen the total number of cases rise to above 90,000 with 2872 deaths. Around 120 patients died yesterday. The lockdown has obviously not worked one bit. Its timing was too premature, draconian measures were imposed much before cases had begun to mount. No attempt was made by the government or the media to assure the public that all data on COVID-19 pointed to more than 80% people developing mild or no symptoms. The majority of infective people would simply shrug off the virus with absolutely no harm to themselves, especially if they were young (as most Indians are) or had no underlying disease.
The number of cases keeps rising every day for the simple reason that more people are being tested now than before. Mercifully, the number of daily deaths are still around 100 and not much more. To put this mortality in perspective, more than 20,000 Indians die every day because of a variety of reasons. This is not the time to discuss those but to stay focussed on what is happening right under our noses.
Millions of people have been displaced, lakhs of businesses are shuttered, all schools closed, restaurants and hotels shut, and millions are without jobs or any means of sustenance. The poor have been hit like never before and the middle class too will soon begin to crumble. Crores of children are corralled with unimaginable psychological adverse effects, domestic and child abuse that largely go unreported must be substantially elevated. These matters are well known.
Most public health doctors worth their salt will endorse the fact that a lockdown if needed must coincide with the peak incidence of cases; it should never be imposed too early or too late. It must be put in place at the time of peak infection. The graph below clearly shows that despite the lockdown, cases in India have shown no decline. There has been a steady increase in the number of active cases since mid-March; what could be the reason for this? The reason is simple, faulty timing of the lockdown.
SARS-Cov-2 is basically a respiratory virus, evolved from nature. Even if man-made, as some conspiracy theorists imply, it is near identical to SARS-Cov-1 and other corona viruses. It is also similar to other viruses that affect the respiratory system, including the flu virus. Every respiratory virus, particularly the flu virus, has a pattern – it emerges in winter, and after infecting people for 6-8 weeks, makes a retreat. In the process, the flu virus manages to kill 30,000 to 60,000 people in the US alone, and many thousands more worldwide, without much hue and cry.
COVID-19 has played havoc in Spain and Italy but as expected, the number of new cases there is declining. This pattern will be the same for almost all countries: a rapid increase in new cases and then a fall in numbers over 4-6 weeks. This has been the natural history of flu as can be seen in the graph from Germany below.
