Just a month after San Francisco became the first city in the country to order citizens to stay at home to stop the spread of COVID-19, the city has actually introduced an ambitious brand-new effort to try to alert locals who might have been exposed to the coronavirus. The city’s goal: Get them all tested and persuade them to self-quarantine in your home for 14 days.
As screening ends up being more widespread, the effort to trace the contacts of those who have tested favorable is seen by public health experts as the next crucial step in trying to manage the pandemic and move beyond the shelter-in-place orders that have actually shut down the majority of the country’s financial and social life. So far, according to San Francisco’s website, the city’s reporting just a little more than 9,000 completed tests for the coronavirus.
” We require this contact-tracing program in location so that we’re geared up to react to new cases and keep the virus from spreading out of control,” Mayor London Breed states.
” Without contact tracing, there’s constantly a threat that we won’t be able to contain additional outbreaks,” says Dr. Mike Reid, and assistant professor in infectious disease at the University of California, San Francisco, who is directing San Francisco’s contact-tracing effort in close cooperation with the city’s Department of Public Health. The company Dimagi is also providing contact-tracing software application that permits staff making the calls to work from another location and send out easy text.
Due to the fact that of issues about personal privacy and civil liberties, the city’s new effort does not include a smart device tracking app, though Taiwan and South Korea have actually used that method effectively. It also, as yet, will not use the contact-tracing app system Apple and Google are collectively creating that utilizes Bluetooth signals to determine contacts that other techniques might miss.
” End-user apps will never ever obviate the requirement for a robust public health action,” Reid states. “Making telephone call, while old fashioned, is the very best method to do what we have to do.”
San Francisco’s technique centers on that standard, fairly low-tech approach: a thorough, voluntary phone interview with a COVID-19- favorable client about their current interactions with buddies, next-door neighbors and coworkers.
Next, without revealing the infected person’s identity, public health employees call that list of people they’ve been in contact with and conduct an extensive interview, asking all these individuals to self-quarantine for 14 days. That’s followed by daily texts or contacts us to each of those contacts to track their health and wellness throughout the two-week monitoring duration.
A public health expert will get on the phone with the person who has tested favorable for the coronavirus to ask: When did you establish any signs or fall ill? After you fell ill, who did you spend time with? What did you do? What dining establishments did you go to? Were you at school?
” You know,” Reid says, “all of those type of everyday activities of life where there might have been a threat of onward transmission.” The calls often last an hour or longer, he says.
Next, now that the city’s broadened contact-tracing capabilities are up and running, Reid says, the tracing team– which includes qualified San Francisco curators, staff in the city lawyer’s workplace and UCSF medical trainees, to name a few– will reach out to the person’s contacts, “and let them know, ‘Hey, you have actually touched with someone that was experiencing COVID-19 We understand that there’s a risk that you might develop signs of COVID, provided your close proximity to that individual, and we would like you to remain at home to quarantine for 14- day period.’ “
In a written statement revealing the program, the city states all conversations are voluntary, confidential “and culturally and linguistically proper. Immigration status will have no bearing on these conversations.”
San Francisco currently has 40 people making these contact-tracing calls. By Thursday, another 70 individuals– consisting of those non-medical staff– will have gone through extensive training by UCSF and the health department and start connecting to the contacts of somebody who’s evaluated favorable. When the shelter-in-place order starts to be reduced, Reid says, the city will need up to 150 people or more to work phones.
In addition, San Francisco will have to significantly ramp up screening if it wants to expand contact tracing.
Sources inform NPR that the city lawyer’s office is working on legal language that will, in theory, assistance impose a 14- day stay-at-home order for clients who test positive for COVID-19 and their close contacts.
City officials state they may, in the future, tap into other sources of data to assist broaden the accuracy of contact tracing.
