COVID-19, the pandemic that has shaken the world, will perhaps change our lives forever. Often, we now talk of a ‘pre-COVID’ world, where business was as usual, and a ‘post-COVID’ world which is the new normal. While the disease, caused by a tiny virus, has affected millions, it has also brought to fore some often-ignored challenges and opportunities to build a better tomorrow. Science has been in the forefront, driving these monumental changes across the world—from understanding the virus and designing a vaccine, to throwing insights on how we could prepare for and prevent the next pandemic.
