(NEW YORK) — When Laura Martin tested positive for COVID-19 last month during an extended stay in California, she was prescribed Paxlovid, the highly touted antiviral drug created by Pfizer.

Just one day after her diagnosis, she started her five-day course of pills, which have been shown to dramatically reduce the risk of hospitalization and death.

Martin, a 63-year-old Boston native who now resides in Canada, said she was thrilled when her symptoms began to subside.

“By the end of [the treatment], on Day 5, I was negative and feeling completely normal like without any symptoms, so I thought, ‘Wow, this is really great. What a great drug,’” Martin told ABC News.

Martin resumed her normal activities, but a week later, she began to feel ill again. When her symptoms worsened, she tested again.

“It came roaring back, and this round two has been much more severe than round one was,” Martin said. “This is like four days of much more significant symptoms than round one.”

​Martin’s case is part of a seemingly rare, but increasingly reported phenomenon of COVID-19 symptom recurrence after being treated with Paxlovid. While it is largely unknown what is causing the reported viral resurgence, scientists say they are investigating. ​​

Pfizer says that it is taking the reported incidences of recurrence “very seriously,” but that the rates mirror those who received a placebo in clinical trials. Experts urge that the benefits of the drug, in preventing hospitalization and death, outweigh the potential risk of a second positive test or symptom reemergence.

In additional analysis of the Paxlovid clinical trial data, the Food and Drug Administration (FDA) reported that most patients “did not have symptoms at the time of a positive PCR test after testing negative, and, most importantly, there was no increased occurrence of hospitalization or death or development of drug resistance.”

Company executives also reported, this week, that the use of Paxlovid continues to expand rapidly, particularly as infection rates across the country rise again. In the U.S., use of the treatment has increased by nearly ten-fold in recent weeks.

The number of locations in the U.S. with Paxlovid supply has grown to more than 33,000 sites now available, a four-fold increase since late-February. In addition, the company reported that there are now more than 2,200 Test to Treat locations now open.

‘Game-changer’

Long heralded as a “game-changer” in the fight against COVID-19, the push to make Paxlovid available to Americans has ramped up in recent weeks, with the White House looking to increase supply of the treatment.

The drug, which was granted emergency use authorization by the FDA in December 2021 for people with mild to moderate COVID-19 at high risk of disease progression, is also strongly recommended by the World Health Organization. It has been shown to be highly effective, estimated to provide an 89% reduction in virus-related hospitalizations and deaths.

However, in recent weeks, a number of patients, who have taken the treatment, have taken to social media to disclose what they say is a perplexing phenomenon of COVID-19 symptoms reemerging after they finished the prescribed five-day treatment course.

Some individuals claimed on Twitter that after their initial symptoms dissipated, leading to a negative test, they are once again testing positive.

“We’re seeing people get better on Paxlovid,” Dr. Shira Doron, an infectious disease physician and hospital epidemiologist at Tufts Medical Center, told ABC News. “But then, when they stop at the end of five days, we’re hearing stories of symptoms coming back and even, tests becoming either more positive, i.e. a darker line, or tests that had gone negative turning positive.”

Studies have found that a dark line can “indicates a strong positive with a high level of virus and is usually seen when people are at or near peak virus load.”

Reports of these “rebound symptoms” are largely anecdotal so far but with an increasing number of questions about the puzzling viral recurrence, scientists across the country are trying to assess what may be happening in new research.

Pfizer taking reports of viral rebounds ‘very seriously’

In February, a 71-year-old man in Massachusetts who had been vaccinated and boosted recovered after being treated for COVID-19 with Paxlovid, Dr. Michael Charness, chief of staff at the VA Boston Healthcare System, who has been researching the phenomenon and recently put out a preprint study last week, told ABC News.

However, around nine days after his initial positive test, Charness said his patient developed cold symptoms and tested positive again for the virus.

Molecular testing soon revealed that the patient’s viral load had increased to an even higher point than when the diagnosis was first made, according to an analysis by Charness and his team.

“We were interested in whether this was a new infection or whether this was maybe an adaptation or mutation that somehow changed the variant,” Charness said, adding that gene sequencing demonstrated that this second positive test demonstrated a recurrence of the original infection in an individual who had no symptoms for a week.

“We just were very struck by that,” said Charness. “I heard from people all over the country and some from other parts of the world, who had had the same experience.”

Representatives from the FDA, the Centers for Disease Control and Prevention and the National Institutes of Health, told ABC News that teams of scientists are investigating the surprising relapse reports, and they will provide further recommendations, if appropriate.

“The phenomenon of recrudescence reiterates the importance of following CDC’s isolation guidance – anyone who develops symptoms of illness during or after isolation should remain isolated, masked, and seek out testing and clinical care,” a representative from the CDC told ABC News in a statement. “Anyone who is concerned about having been exposed or who for any other reason wants to determine their infection status should test for COVID-19.”

The FDA stressed that the reports “do not change the conclusions from the Paxlovid clinical trial which demonstrated a marked reduction in hospitalization and death.”

The viral recurrence had been observed and reported in Pfizer’s application to the FDA, last year, in which the company said several trial participants had appeared to “have a rebound” of COVID-19 around day 10 or day 14.

Pfizer executives said Tuesday that they are taking the reports “very seriously,” but they do not believe that it is related to the drug, given that the same rate of rebound was observed in people who took the placebo. Further, no connection was noted between the viral load increase and subsequent severe illness.

“We’ve taken a preliminary look at our high-risk data, and so we’ve seen for example, that we have about an incidence about 2% of that viral load rebound, but we also see the same, or close to the same, percent in the placebo arm. So it’s something that’s not particularly associated with Paxlovid itself, but may have something to do with the virus itself,” Dr. William Pao, Pfizer’s executive vice president and chief development officer, said during an investors call on Tuesday. “It’s preliminary data so far, we again take it very seriously. But it’s very current, and a very low incidence, and we continue to learn as we go.”

A representative from Pfizer told ABC News that although it is too early to determine the cause, initial indications suggest an increased viral load is both uncommon and not uniquely associated with the Paxlovid treatment.

“We remain very confident in its clinical effectiveness at preventing severe outcomes from COVID-19 in high-risk patients,” the representative said.

Reports uncommon but happening ‘frequently enough’

Although official reports of these relapses still appear to be rare, such occurrences are happening “frequently enough” in those treated with Paxlovid that Charness said that it should be studied further.

“I think the first step in studying something is to know that it exists,” he explained, adding that it is particularly important for clinicians to be informed about potential rebounds, and for the public to know, so that people do not become unduly alarmed.

Thus far, researchers know very little about the reason for the recurring symptoms.

Of critical importance in the investigations is whether an individual, in the midst of such a rebound, remains infectious, Charness said.

“We are sufficiently concerned about whether people can transmit, when they’re on day 12 and 13 and 15, that we are essentially recommending that when people have a recurrence, a rebound, that they restart their isolation, and isolate until their antigen test is negative,” Charness said. “We’re seeing people whose antigen test stays positive for a week after they rebound, which means that they’re well outside the CDC’s 10-day guidance.”

Should you experience a viral rebound, the FDA is now recommending that health care providers and patients refer to CDC guidance, wear a mask and isolate if they have any COVID-19 symptoms — regardless of whether or not they have been treated with an antiviral.

Charness and his team are also encouraging their patients to start their isolation period over again and stay away until their antigen test is negative.

“It’s important to exercise caution until you clear the virus the second time,” Charness said, further urging people to notify their provider.

In terms of further treatments, Charness noted it is still largely unclear what patients should do. While there are no limitations, within the authorized label, around additional usage of the drug for a subsequent COVID-19 infection, according to Pfizer, the FDA said “there is no evidence of benefit at this time for a longer course of treatment … or repeating a treatment course of Paxlovid in patients with recurrent COVID-19 symptoms following completion of a treatment course.”

Despite the reports of rebounding, health experts stress that Paxlovid is still largely achieving its original goal, to keep people out of the hospital, and severe disease at-bay.

“The bottom line is if it prevents hospitalization, if it keeps you from progressing to severe disease, hospitalization and death, the fact that you might have a recurrence of some of the symptoms and even the recurrence of a positive test is sort of secondary,” said Doron. “The main thing is Paxlovid is to prevent progression to severe disease [and] hospitalization, and it does. So, it’s still doing its job.”

(NEW YORK) — Amid a nationwide wave of what they call legislation targeting LGBTQ rights and representation, advocates are concerned about the impact on the mental health of LGBTQ youth.

“LGBTQ youth suicide is a major public health crisis,” said Amit Paley, chief operating officer of The Trevor Project, a nonprofit focused on suicide prevention among LGBTQ youth.

This population already struggles disproportionately with mental illness and suicide. The Centers for Disease Control and Prevention reports LGBTQ students are about four times more likely to have attempted suicide than their heterosexual peers, according to a study released in late March that tracked data from 2009 to 2019.

That same study showed LGBTQ youth self-reported persistent feelings of sadness or hopelessness at more than twice the rate of their heterosexual peers.

Matthew Goldenberg, a psychologist at the Seattle Children’s Hospital Gender Clinic, explained that additional everyday “environmental factors” create a higher prevalence of suicide attempts and suicidal thoughts among LGBTQ youth.

He cited family conflicts, heightened stress, lack of community support, bullying and whether or not a child has an affirming environment as potential risk factors.

“I think the really important point to make is that LGBTQ young people are not born inherently more likely to attempt or consider suicide,” Paley said. “LGBTQ young people end up attempting or considering suicide because of the stigma and discrimination and isolation that they face in society.”

Paley explained The Trevor Project has been monitoring an upward trend in reported suicidal thoughts and suicide attempts among this population over the last few years.

“And that coincides with a really difficult time for so many LGBTQ young people, as they are being attacked in legislative contexts,” Paley said.

More than 300 bills targeting LGBTQ people have been introduced so far this year, according to the Human Rights Campaign.

“When you hear people in positions of power saying people can’t talk about your identity in schools, that you can’t use the restroom, that you can’t access medical care. That’s very scary,” Paley said. “Those policies are harmful and dangerous, but even more than that, the words around them really impact the mental health of LGBTQ youth.”

Along with the impacts of hostile legislation, LGBTQ young people are feeling the mental health effects of the COVID-19 pandemic, which has heightened attention on mental health concerns across the nation over the last two years.

“The pandemic has been incredibly difficult for LGBTQ youth, who may not be able to live as their authentic selves when they’ve been home so much during the last few years, and that’s really exacerbated the mental health crisis among that population,” said Hannah Wesolowski, chief advocacy officer for the National Alliance on Mental Illness.

On Tuesday, co-chair of the congressional LGBTQ+ Equality Caucus, Rep. Sharice Davids, D-Kansas, introduced the Pride in Mental Health Act. The bill would create a new program at the Substance Abuse and Mental Health Services Administration (SAMHSA) to “assess and improve LGBTQ+ youth mental health,” according to a press release from the caucus.

The legislation would also amend the Child Abuse Prevention and Treatment Act to provide specific protections for LGBTQ youth with the aim of improving data collection related to abuse and neglect among that population.

“Mental health is a growing concern for families and communities across the country, and frankly, we are failing many of our most vulnerable children on this issue,” Davids said in a press release. “When we talk about improving mental health, we’re really talking about saving these kids’ lives.”

Resources to support LGBTQ young people experiencing mental health crises are available. The Trevor Project offers a crisis line via phone, text and online chat for LGBTQ young people. Trans Lifeline operates a peer support and crisis line for transgender people.

The National Suicide Prevention Lifeline offers crisis support services as well. In July, that hotline will transition to a new three-digit number, 988, that advocates envision as the mental health equivalent of 911.

The Trevor Project was among the advocates for the establishment of the new number for the Lifeline. Paley says the organization is working with the Department of Health and Human Services SAMHSA to create an integration in the Lifeline service to connect LGBTQ young people who call in to counselors specifically trained to support and understand their needs.

“I think the biggest thing about providing these crisis resources is they need to be culturally competent,” Wesolowski said. “Somebody who identifies as LGBTQ talking to somebody who can understand their experience is really important to de-escalating that.”

There is no current timeline for when that integration with the Lifeline will be up and running. Efforts to get the new number launched are still underway and complicated by underfunding.

“We think the intention of 988 is so incredibly important,” Paley said. “We need to make sure that the federal government puts the resources to execute it properly. And so that’s what we’re in discussions about to make sure that we can provide more access for LGBTQ youth.”

If you are struggling with thoughts of suicide or worried about a friend or loved one, help is available. Call the National Suicide Prevention Lifeline at 1-800-273-8255 [TALK] for free, confidential emotional support 24 hours a day, 7 days a week. You can also reach the Trevor Project at 1-866-488-7386 or the Crisis Text Line by texting “START” to 741741.
