I’m An Infectious Disease Doctor Yet I Couldn’t Protect My Family From The Delta Variant

by Joseph K. Clark

Studying this novel virus and educating the public about it has consumed my days since early 2020. It was especially troubling when my husband, son, and I contracted the Delta variant of COVID-19 last month. My job as a public health physician is to protect your family from COVID-19 — and I should have been able to defend my own.

In December 2019, I was the director of infection prevention at an extensive academic health system in Singapore. On New Year’s Eve, while most of the world remained unaware of the looming danger, I learned about a new respiratory syndrome from my emerging infectious disease network. We were hearing troubling news about the syndrome and began safety preparations at the hospital in January 2020, while we were also struggling to understand more about it.

We opened an emergency department for suspected COVID-19 cases in an open-air tent without high-tech air handling systems. Despite seeing thousands of patients there, we had no virus transmission among any of our staff. To prevent transmission, we used strict infection prevention protocols (you can read more about them here and here).

When I moved back to the United States in July 2020, I started a new public health role where COVID-19 testing and prevention were a priority. I’ve authored academic papers on COVID-19 and consulted for international public health agencies. It’s safe to say that since the beginning of 2020, COVID-19 has been the focus of my professional life.

I use the same infection prevention measures that I advise the public personally. For over a year, I have not done things that I consider moderate to high risk, including traveling by air, eating at indoor restaurants, attending concerts, or visiting movie theaters or gyms. My husband and I were vaccinated as soon as we were eligible; we avoided large gatherings and continued to wear face masks in indoor public spaces even after the Centers for Disease Control and Prevention (C.D.C.) relaxed mask recommendations for fully vaccinated people in May.

Delta Variant

Despite our family’s precautions, my 7-year-old son (I’ll refer to him as B.B.) was exposed to the virus through an outbreak at his outdoor day camp, which should have been a lower-risk setting. He wore a mask whenever possible. We did not take unnecessary risks, and yet here we are. So why was I unable to protect my own family? The reasons should concern you.

1) Working parents like me need child care.

Working parents, like my husband and me, need a child care even when work is mostly remote. After a full year of virtual school, I wanted B.B. to be around children his age. We enrolled him in an outdoor day camp where he underwent daily symptom checks at drop-off. Given all the other precautions in our lives, we understood this was a calculated risk ― one that we were willing to take.

We know that asymptomatic people can transmit the virus that causes COVID-19 and that children may have few symptoms. But unless we identify all asymptomatic “silent” cases of COVID-19 in children, it will be nearly impossible to prevent outbreaks. This means measures such as symptom screenings and temperature checks at camps and daycares can be less effective. Parents with few childcare options may be tempted to drop their kids off even if they have been exposed to COVID-19 or have mild symptoms, like a runny nose.

The routine use of rapid antigen tests for the virus has been one way to identify early or asymptomatic infections in school-aged children. Even though these tests are now widely available in our area, routine testing was not in place at my son’s camp.

2) Universal masking is the best protection, but it’s no longer mandated in many areas.

I took comfort in the infection control measures outlined in the introductory camp materials. I had hoped that an outdoor camp — where children would wear face masks in indoor spaces, and counselors would wear them at all times — would be relatively low risk. When I dropped B.B. off for his first day of camp, the counselors wore masks. But by the end of the first week, this had stopped, and B.B. told me that counselors and campers often removed their covers indoors.

Masks are fantastic tools for preventing the transmission of viruses, but they are most effective when both infected and susceptible individuals wear them. By wearing a mask, B.B. was doing a great job protecting other campers, but the other campers and counselors weren’t offering him the same consideration. 

When the C.D.C. released its recommendations in May advising that fully vaccinated individuals no longer needed to wear masks, many of my public health colleagues were perplexed for a couple of reasons: It is hard to tell who is vaccinated and who is not, and we know that vaccine “breakthrough” infections can occur (more about that later). 

Not wearing a mask may not personally affect a fully vaccinated, healthy adult. But the decision to stop requiring acts in public spaces creates an unsafe environment for the most vulnerable: those immunocompromised and people ineligible to receive the vaccine, either due to age or an underlying medical condition.

3) Transmission is challenging to prevent between household members.

We had no warning that B.B. had been exposed to COVID-19. When he developed a high fever, I tested him using a rapid home COVID-19 antigen test and called the local health department. Had B.B. been under quarantine from his exposure, we could have worn masks at home and taken extra precautions. As it was, without notification, my husband and I were likely exposed to high levels of the coronavirus in the days preceding B.B.’s symptoms.

Even if we had known about the exposure, we might not have avoided household transmission. It is exceedingly challenging to parent a sick child without exposing yourself. Young children cannot adhere to infection control measures such as safely disposing of contaminated tissues or washing their hands. Once a child brings home COVID-19, the risk to other household members is present even when families attempt to distance themselves.

4) The delta variant is here, and that changes everything.

In May, when the C.D.C. relaxed mask recommendations for fully vaccinated people, it counted on vaccines’ remarkable efficacy. Vaccines remain the best tool against COVID-19, especially against severe illness, hospitalization, and death, even in emerging variants.

However, when the guidance was issued, things were not looking so rosy around the world, leaving many of us in public health scratching our heads about the timing. The delta variant had already wreaked havoc in India. Early reports from the United Kingdom had signaled that the variant was more transmissible and caused infections in vaccinated people (aka “breakthrough infections”).

We now have data to suggest that the delta variant (compared to the original strain of the virus) is up to twice as transmissible, and the amount of detectable virus in infected individuals is much higher. While the currently available vaccines offer good protection against the delta variant, efficacy may be somewhat reduced, and people with breakthrough infections can likely transmit the virus to others.

The following variants may be more transmissible, deadlier, better able to evade vaccines, or combine these factors. The delta variant will not be the last COVID-19 variant we see. New mutations will arise as long as the coronavirus spreads, and the lambda variant is already causing fresh concerns.

Where do we go from here?

The pandemic is far from over, and our only hope for moving into the fall with any degree of normalcy is to better protect unvaccinated kids under 12. Families cannot do this alone, and we need a set of community safeguards.

These safeguards include universal masking (for both vaccinated and unvaccinated people) in schools, camps, daycares, and other settings where children spend their time and ensuring that teachers and staffers are vaccinated. We need regular testing programs for asymptomatic children in these settings and better support for parents caring for sick children. We need to continue robust contact tracing and quarantining after exposure in the community, including exposure in schools, camps, and daycares.

Public health professionals like me know how to prevent COVID-19 transmission. Now, we need communities and individuals to follow our guidance. I could not guarantee the safety of my family because implementing these simple safeguards requires a social contract ― a societal agreement to cooperate to protect the health and safety of our children, even if it inconveniences us or involves compromise.

As new variants emerge, we must reevaluate the risk of transmission from outdoor contact, fleeting contact, and vaccinated individuals.

We will need to reevaluate how we think about breakthrough infections among vaccinated people. While breakthrough infections tend to be less severe than infections among unvaccinated, this does not mean all breakthrough infections are mild or don’t cause distress or disruption for those affected. My husband and I (relatively healthy and in our mid-40s) had fevers, chills, headaches, coughs, and shortness of breath.

More than 4,000 children in the U.S. have developed multisystem inflammatory syndrome, a rare but severe condition associated with COVID-19, which can be life-threatening. Pediatric COVID-19 infections are also typically thought of as mild. Still, B.B. had fevers for over a week and required an emergency department visit, where he underwent a blood draw, a chest X-ray, and an electrocardiogram.

As a society, we are responsible for preventing suffering for the most vulnerable among us. Unvaccinated people keep community transmission going and provide a reservoir for the virus to mutate. While many people are unvaccinated by choice, we must prioritize and protect the unvaccinated due to their age or underlying medical conditions. By protecting our children, we will not only prevent severe pediatric complications but also protect families and entire communities.
