In the final week of August, one of many world’s foremost poxvirus specialists retired from the Facilities for Illness Management and Prevention.
To exterior eyes, the timing of Inger Damon’s departure may very well be seen as odd or unlucky, on condition that after years of relative obscurity, poxviruses are on the middle of the world’s infectious ailments radar, due to the continuing monkeypox outbreak. Although the expansion of case numbers had slowed, there was no signal the disaster was beneath management. Many challenges stay forward.
However Damon and her husband, additionally a CDC scientist, had introduced their intentions to retire earlier than the monkeypox outbreak was detected within the spring. The worldwide unfold of the virus — which Damon believes will be contained, however not anytime quickly — didn’t alter their plans.

Damon headed the CDC’s Division of Excessive-Consequence Pathogens and Pathology — assume the baddest of dangerous bugs. Ebola and rabies, anthrax and smallpox, Rift Valley fever and monkeypox. She took the job within the spring of 2014, when Ebola was exploding in an unprecedented approach throughout West Africa. Within the intervening years, her group has rolled from disaster to disaster.
Retirement for some means journey journey or lengthy day by day walks, studying for pleasure, or the exploration of latest hobbies. In Damon’s case, there’s a lot of work left on the horizon. She is a member of the World Well being Group’s committee tasked with investigating the origin of the Covid-19 pandemic, sits on the worldwide well being company’s advisory committee on variola virus analysis, and is a member of the poxvirus research group of the Worldwide Committee on Taxonomy of Viruses.

She’s even provided to assist out colleagues in her previous group, in the event that they want her.
“I stated I might pitch in on a volunteer foundation to assist as wanted, if I may pitch in,” Damon instructed STAT in an interview throughout her final week on the CDC. “We’ll see in the event that they take me up on it.”
Within the interview, she mentioned the years of labor that gave the world instruments with which to reply to the monkeypox outbreak — a safer vaccine, an antiviral drug, diagnostic checks that have been obtainable from the leap.
This transcript of the dialog was edited for size and readability.
It’s an uncommon time for one of many world’s main poxvirologists to be leaving a job like this.
I suppose I’d say I’m at some extent the place I look again and I say: I’ve been capable of contribute to this. I’ve been capable of work with of us right here at CDC and helped develop the diagnostics which are getting used now, whether or not in public well being labs or within the industrial labs. I’ve helped to coach a era of virologists and clinicians who’re comfy pondering via this illness and the complexities of it. I labored to assist practice and assume via what we have to do to know illness ecology. I’ve helped different individuals in international locations the place illness is considered endemic when it comes to working with the Democratic Republic of Congo, or outbreaks within the Republic of Congo, or serving to practice the people who find themselves supporting work in Nigeria now, whether or not it’s sequencing or diagnostics or doing fine-tuned epidemiologic research to know dangers. So I really feel like I’ve contributed to what we’re doing now, and I really feel like now we have a very nice, skilled cadre of individuals able to exit and additional unfold data.
There’s a lot of good individuals developing. So that they’ve obtained it coated.
Your division at CDC, high-consequence pathogens, covers a number of dangerous actors.
It actually does.
Over the course of your profession, is there a pathogen that has given you extra sleepless nights than others?
That’s a tough query! I’ve had a lot of sleepless nights. I’ve had sleepless nights about working within the BSL-4 lab with variola virus [the eradicated virus that caused smallpox], and doing experiments there to develop virus for sequencing, or for doing research taking a look at antiviral efficacy in non-human primates.
I’ve had sleepless nights pondering via Ebola response actions, and the Ebola response within the U.S. in 2014 to 2016. And internationally, it was only a super elevate of: How can we get achieved what initially appears inconceivable and make it potential?
Do you’ve a favourite pathogen?
[Laughs.] I might say a favourite pathogen could be to unlock the mysteries of what allowed variola virus to be such an environment friendly human pathogen. I don’t assume that’s one thing we’ll ever perceive. It’s a thriller that we are going to most likely by no means resolve.
Let’s return to monkeypox. It actually discovered a lane, didn’t it? A approach to get out into the broader world by infiltrating networks of males who’ve intercourse with males.
Sure, and I believe it was additionally at a time when individuals had been confined at dwelling for a few years due to Covid, hadn’t had the standard freedoms or experiences. And so it appeared to be a time when Covid vaccine was there and we may take our masks off. It was a time when individuals may work together with one another in a extra social approach.
I used to be emailing lately with Anne Rimoin, [a monkeypox expert at the University of California, Los Angeles]. She has critical considerations about how properly the monkeypox vaccine will work within the present context, the place lots of people being contaminated are contracting the virus throughout mucosal membranes. Her argument was these vaccines weren’t created to guard in opposition to this type of intense publicity. Do you are concerned about that?
I do. I believe that is one thing that now we have to very fastidiously comply with. And we have to actually be very forthright in serving to the neighborhood who’s in danger perceive what the limitation of our data is, and why and what we do learn about completely different manifestations of the virus via completely different routes of infections. That’s actually one thing we realized extra about in 2003 within the U.S. outbreak. There have been completely different ways in which sickness rolled out, whether or not you’re contaminated via a chew or a scratch.
Right here we’re seeing very extreme pharyngitis [sore throat]. We’re seeing extreme proctitis [inflammation of the lining of the rectum]. We’re seeing actually extreme lesions on the glans of the penis, that are extremely painful, and in uncircumcised males are actually creating challenges in lots of circumstances. And so I believe, getting the message out about what we all know, about what we’re seeing at this cut-off date is important for individuals to make knowledgeable choices.
Monkeypox exercise in Nigeria from 2017 onward appeared to recommend one thing completely different was occurring there. Did your group assume the virus had gotten into males who’ve intercourse with males there?
In the event you have a look at the Lancet ID paper and the CID paper that got here out from Nigerian co-authors [in 2019 and 2020] that is the place you’re beginning to see extra proof and descriptions of penile lesions. And we’re seeing loss of life in these with HIV which is unmanaged. This had not been reported earlier than. The male-to-female ratio is barely greater than what was reported in different research, the place the idea is that the first publicity was looking or meals preparation.
There was nothing that was like a smoking gun. However there have been clues that there was illness in a special demographic.
Do you’ve a way of whether or not this unfold internationally goes to be contained? Do you assume it’s potential?
If we have a look at the developments in case counts, we’re starting to see a leveling off, and in some circumstances a lower in case counts. And in order that’s a very good signal.
So I believe what we have to know is what has led to that? What have been the efficient interventions? After which we have to multiply these. And we’d like to verify we’re reaching the entire communities in a approach that they perceive the impression of these interventions and the advantage of these interventions. And I believe we’re starting to be at that place within the U.S. outbreak.
That doesn’t actually reply my query. Do you assume it’s going to be contained, or will be contained?
[Long pause.]
I do. However I believe it’s going to take a while. And I’m not happening the document about how a lot time it’s going to take.
Individuals preserve speaking about it within the context of stopping the outbreak in their very own nation. If monkeypox is stopped in america however takes root in Romania or Israel or Portugal or another nation, it’s successful a battle however not the warfare.
Sure. It actually needs to be a worldwide effort, in any other case it’ll merely be reintroduced once more.
Is that this instructing us that we might have to assist endemic international locations add monkeypox vaccine into their vaccination schedules?
The choice to not proceed with routine smallpox vaccination [after smallpox eradication] was based mostly on research within the Democratic Republic of the Congo within the Eighties. What the research finally confirmed is that they felt that absent reintroduction from a reservoir host that monkeypox wouldn’t perpetuate in people. There was a advice that routine smallpox vaccination [which also protects against monkeypox] was most likely not going to be of profit.
I believe we’re on the crux of the nook of what can we now take into consideration the function of vaccination right here? As this outbreak evolves, will we have to return and see if there are extra populations that we expect are at continued threat? Or have we achieved an sufficient job to regulate this and remove additional illness unfold?
So it may very well be that vaccine will change into a software that can be utilized in populations which are thought of to be in danger — that the risk-benefit ratio is value it. However we’re not fairly there but.
If I’m listening to you accurately, you’re not less than open to the notion that the calculations that have been achieved based mostly on the research in DRC many years in the past don’t tackle the present context?
Appropriate. They’ve modified.
It’s solely been just a few months for the reason that U.Okay. introduced it had discovered monkeypox circumstances amongst males who hadn’t traveled exterior the nation however who had intercourse with different males. Has anybody achieved any analysis but to indicate whether or not the mutations seen within the viruses on this outbreak have given monkeypox a greater shot at human-to-human transmission?
I’ve not seen something printed but, or something in preprint but about that. I do know that there are a variety of investigators who’re taking a look at that. I’ve heard early descriptions however I’ve seen no knowledge.
The problem is creating an animal mannequin that’s going to provide the data that recapitulates what we’re seeing within the human inhabitants.
How do you try this with this transmission state of affairs, the place individuals are largely being contaminated throughout oral and anal intercourse?
Yup.
Will we do mucosal challenges? What’s the proper host whose immune system — innate, adaptive — is consultant or will be studied to tell the human system? What we’ve been pushing on for a very long time is that there actually must be some good, well-done pure historical past research of people, the place people who are available for care are adopted intently. The evolution of rash is evaluated. historical past is taken about potential routes of an infection. Contacts of that particular person are enrolled. They’re monitored or assessed. You get details about potential dangers. Which may be the richest supply of data to assist us perceive the baseline of what’s occurring on this specific outbreak.
When you concentrate on this outbreak — which is form of an interesting approach to cap a profession at CDC — are there issues that you simply realized about monkeypox that basically floored you?
I suppose what I might say is, there are issues that I’ve seen on this outbreak that make me ask extra questions. Extra questions than I had earlier than. There’s all types of actually fascinating questions in regards to the virus and the host and the virus-host interplay.
After which I believe there are the preparedness and response questions. How do our vaccines work at this cut-off date? What can we inform individuals about their effectiveness and the way they’re going to guard? What do we have to study in regards to the antiviral that’s getting used? When is it greatest used? How does it have an effect on illness? How does it have an effect on sickness?
What does retiring from the CDC imply? You’ve provided to assist out should you can. And also you’re going to proceed to work on WHO committees, aren’t you? Will you find yourself at a college?
I’m going to take a pair months off and journey and go to a bunch of weddings and atone for the talks that I haven’t written but and the guide chapter that’s overdue.
In different phrases, you’re not going to be in a hammock sipping piña coladas?
Among the time. Simply perhaps with my laptop computer.
