ABC on COVID-19

The paper “The effect of travel restrictions on the spread of the 2019 novel coronavirus (COVID-19) outbreak”, published in Science on 06 March by Matteo Chinazzi and co-authors, considers the impact of travel restriction in Wuhan on the propagation of the virus. (Terrible graph by the way since the overall volume of traffic dropped considerably after the ban.)

“The travel quarantine of Wuhan delayed the overall epidemic progression by only 3 to 5 days in Mainland China, but has a more marked effect at the international scale, where case importations were reduced by nearly 80% until mid February.”

They use a SLIR (susceptible-latent-infectious-removed) pattern of transmission, along with a travel flow network based on 2019 air and ground travel statistics, resorting to ABC for approximating the posterior distribution of the basic reproductive number. It is however unclear to me that the model is particularly accurate at the levels of the transmission pattern (which now seems to occur much earlier than when the symptoms appear) and of the detection rates (which vary greatly from one place to another).

and it only gets worse…

“Medicaid pays for most of the 1.4 million people in nursing homes (…) With more than 70 million people enrolled in Medicaid, the program certainly faces long-term financial challenges. Certainly, nursing homes would be part of those cuts, not only in reimbursement rates but in reductions in eligibility for nursing home care.” NYT, June 14, 2017

“…the architects of the Trump contraceptive reversal, Ms. Talento, a White House domestic policy aide, and Mr. Bowman, a top lawyer at the Department of Health and Human Services, have the experience and know-how that others in the administration lack. As a lawyer at the Alliance Defending Freedom, Mr. Bowman assailed the contraceptive coverage mandate on behalf of colleges, universities and nonprofit groups that had religious objections to the rule. Ms. Talento, a former aide to Senator Thom Tillis, Republican of North Carolina, spent years warning about the health risks of birth control pills.” NYT, July 11, 2017

“Mr. Trump’s revised executive order, issued in March, limited travel from six mostly Muslim countries for 90 days and suspended the nation’s refugee program for 120 days. The time was needed, the order said, to address gaps in the government’s screening and vetting procedures. Two federal appeals courts have blocked critical parts of the order. The administration had asked that the the lower-court ruling be stayed while the case moves forward. The court granted part of that request in its unsigned opinion. NYT, June 24, 2017

The proposed legislation, which Planned Parenthood labels “the worst bill for women’s health in a generation,” would strip the organization of federal funding for one year and bar any federal tax credits from being used to help buy private health plans that cover abortions.” NYT, June 23, 2017
