In general it is quite hard to get accurate representative samples if there is an unknown or high degree of variance between locations (are you scaling up the right samples to arrive at an accurate estimate). As for knowing which strains, that would certainly be useful but it requires significant sequencing infrastructure, which is not easy to scale up. The Washington Post noted (https://www.washingtonpost.com/world/2021/04/29/india-surge-variant-genetic-sequencing/ https://www.washingtonpost.com/world/2021/04/29/india-surge-...) that India is #102 among nations in sequencing per capita. It notes: > Sequencing takes a high level of infrastructure and funding. India, which spent very little per capita on health care before the pandemic, has not been able to quickly make the investments to scale up, said Gupta.
