A Q&A with Anne Rimoin, PhD, MPH

Q

Have the variety of COVID-19 instances peaked but?

A

We now have no approach of realizing whether or not the virus has peaked or not as a result of we don’t have widespread testing in place. That’s the solely option to know who’s been contaminated and who hasn’t.


Q

How far-off are we from safely ending social distancing and opening the financial system up once more?

A

Testing is what’s going to assist us perceive once we’re going to have the ability to reopen the financial system. Till we’ve got a vaccine, we’re going to must depend on understanding who’s been contaminated and who hasn’t, who has immunity and who doesn’t.

Antibody checks are a giant query proper now. The checks search for antibodies within the blood as a sign that someone has been contaminated and mounted an immune response. The hope is that the presence of antibodies is a sign that an individual is protected against future an infection. Nonetheless, the World Well being Group has acknowledged that individuals ought to use warning decoding antibody checks. A lot of the antibody checks in the marketplace should not very correct and haven’t gone by rigorous FDA scientific evaluate.

Having inaccurate antibody checks in the marketplace is problematic as a result of folks might get a false optimistic and imagine that they’ve immunity after they really don’t. Moreover, antibody checks inform you solely who’s been contaminated and who hasn’t. Presently, they don’t inform us whether or not someone is immune, how lengthy that immunity might final, or whether or not an individual will be reinfected. Solutions to those key questions will play a giant half in when the nation is reopened and assist us perceive how many individuals have had an an infection—whether or not that an infection was symptomatic or asymptomatic—and the way the illness spreads in populations.

Till we’ve got additional info, we can not say folks with antibodies are immune. It’s additionally fairly believable that we might see that there are various ranges of immunity from individual to individual. It will not be a black-and-white difficulty. Immunity would possibly range based mostly on folks’s immune techniques, their age, and different elements. There may very well be solely partial safety or people who find themselves not protected in any respect by antibodies. We’re too early within the scientific course of to have the ability to know any of this for positive.


Q

What about herd immunity?

A

What we’re doing proper now’s utilizing a blunt instrument: We’re utilizing social distancing to make it possible for the virus doesn’t have any option to unfold. The idea of herd immunity is vital when it comes to basic illness prevention to make it possible for sufficient folks within the inhabitants are immune and that these individuals who do not need immunity are not possible to come back into contact somebody who’s at present contaminated. However the current antibody checks don’t give us any indication of whether or not an individual is immune or not, so we are able to’t know whether or not there may be herd immunity.


Q

What would that transition again to opening up the nation appear to be?

A

The very first thing that we’ve got to do is get testing up and operating. We at present don’t have widespread testing out there to find out who’s sick and have the ability to isolate these folks. The testing difficulty is a provide chain difficulty: We don’t have the reagents or the supplies which are wanted, and we don’t have the manufacturing in place to produce sufficient checks. We additionally want to find out who’s been uncovered to sick folks by contact tracing, which is a really time-consuming course of. We now have to make it possible for these individuals who have come into contact with somebody with COVID-19 are quarantined for an applicable time frame to be able to restrict the unfold.

We now have to be very cautious about policymakers creating sweeping financial and social choices—reminiscent of plans to reopen companies or colleges—based mostly on restricted information and assumptions based mostly on what’s identified about different viruses. We have to perceive this novel virus earlier than we transfer too rapidly towards reopening the nation. If we reopen too quickly, all of the unimaginable features that we’ve made by the good sacrifices of each individual on this nation and other people globally will lose floor. There can be a resurgence of instances if we don’t have good security measures and infrastructure in place.


Q

What COVID-19 analysis are you concerned with at UCLA?

A

The important thing factor we’d like is widespread testing and in addition testing in key populations, like our well being care staff. We have to check our well being care staff commonly as a result of having a unfavorable check for the virus at present doesn’t imply you’re going to check unfavorable tomorrow.

I’m main a examine at UCLA the place we’re going to be commonly screening each hospital employee within the UCLA well being care system. And as soon as we obtain funding, we’re going to be scaling up testing to first responders all through Los Angeles as nicely. This common testing will enable us to see whether or not these staff are asymptomatically contaminated and doubtlessly passing it on unwittingly to sufferers or colleagues or bringing it house to their households, which is a serious difficulty.

We’re additionally planning to gather blood from well being care staff to higher perceive immunity and the outlying questions with antibody checks—whether or not having antibodies means they’re immune, how lengthy immunity lasts, and whether or not or not folks will be reinfected. Most of these longitudinal research happen over a protracted interval to evaluate outcomes over time. This examine will span a 12 months and can assist us assess these extraordinarily vital questions that can enable us to guard our frontline well being care staff and in addition decide when it is likely to be protected to reopen the financial system.
