The Indian state of Kerala has experience tackling virus situations. Most recently with a Nipah brain damaging virus in 2018. For cases to double Kerala has 72 days, compared to a national average of 8 days. With total 437 cases and 3 deaths Kerala has shown "the importance of early tracking, screening, home quarantine, strict isolation and public participation," says Dr. B Iqbal, chairman of the Kerala state expert committee on coronavirus in an interview with DW. com. The first case was a medical student arriving from Wuhan on Jan. 24, diagnosed 6 days later. During the Nipah virus crisis Kerala limited deaths to 17. Kerala is an example of the importance of a well funded and well established and organized health care system. The Indian state of Chhatisgarh has taken a proactive approach color zoning districts. Of 28 districts 23 are free of coronavirus. Less cases and zero deaths.The key state health minister says was early preparations and then luck playing a part.

These simulations show the  importance of flattening the curve for coronavirus especially the steep jump in the curve when it grows exponentially as people mingle in crowded environments, on trains and subways, and in public gatherings of more than 10 people. This is shown here in four different simulations in the Washington Post. Social distancing and quarantine worked in China, Taiwan, Singapore and South Korea. Though the attempted quarantine simulation here does not cover the situations in China, Taiwan and Singapore where quarantine has worked and was the only way to tackle the coronavirus in time to do least damage. Additional simulations would show the way it was limited in Singapore through contact tracing and mandated staying at home for all who have come in contact with affected persons. And in South Korea a simulation could show how this worked through containment by testing and limiting spread, or China by an effective quarantine or lockdown of a city or province.  The basic idea is to limit contact and separate so that intermingling is restricted to as few places as possible for a limited period during which health authorites can achieve a controlled situation through systemwide organized efforts.  ...

Some of the concern about the economy comes from the economic damage done by the coronavirus. The longer the shutdowns continue the more the damage. About 17 million have filed claims for unemployment benefits. The WSJ consensus of 57 economists is that 14.4 million jobs will be lost in coming months, and the unemployment rate will rise to a record 13% in June, from a 50 year low of 3.5% in February. The earliest the economy could go back to the level in February 2020 is 27 months says the WSJ economist survey. The brighter side of this comes in two aspects of this pandemic recovery curve. By flattening the curve and strict testing, contact tracing and isolation till the vaccine is developed about half the jobs lost can be recovered by the end of summer, says Moody's Analytics. The vaccine a year from now or in 9 months by November 2020 would allow the economy to recover faster. A more optimistic view comes from Daiwa Capital Markets which predicts many of people laid off will be recalled quickly allowing the labor market to recover in 6 months by September or October 2020. Only finance and real estate might take longer but most of the industries where the vast majority of jobs are could be back on their feet. The credible evidence supporting this perspective of a rebound comes from Colorado and Washington which require large employers to specify whether layoffs are temporary or permanent, 70% this year are temporary. Compare this to the prior 2009 recession where this figure was less than 1%- as reported by WSJ. The big push in this direction will be the $2 trillion that the Trump administration and U.S. Congress have committed to this task. Even more so is the determination of president Trump to protect American workers at all costs, that every job counts, and that businesses without exception to get the money have to show that workers are retained. The very success of the aid is being judged by how quickly people are back to work. Now for a look at where the situation is today- Oxford Economics, a UK based forecasting and consulting firm, projects 27.9 million jobs lost with industries other than those ordered to close making up 8 to 10 million of that number. It projects April's report will will capture late March layoffs. It will show cuts to 3.4 million business services workers, including lawyers, software groups, architects and consultants, advertising professionals, in addition to 1.5 million non-essential healthcare workers, 100,000 information workers. One conclusion of this report is that the virus does not discriminate across business groups and business service workers are also affected. Many companies that were hiring will cancel that move and many will cut hours worked. Many of these business services are not a priority. Hospitals are affected too, as they cut elective surgical procedures and routine care that are major revenue sources. Some are now charging for telemedicine visits to maintain some revenue stream. State and local governments employ 20 million workers. As tax receipts decline these local governments will face choices of cutting payrolls and services without enough federal government relief. In a way laying off workers and having them take unemployment benefits shifts that burden to the federal government so that services for overtime to police and paramedics, retention and deployment of nurses in schools.    ...
