Erin Garcia de Jesus

Erin Garcia de Jesús covers how microbes, viruses and other health threats shape everyday life, with a focus on explaining what new research means for people rather than just what it found. She is a staff writer at Science News, where she reports across infectious disease, vaccines, antibiotic resistance, genetics and broader public health.

Microbes, vaccines and the shifting threat of infectious disease

Garcia de Jesús’ core reporting traces how microbes move through the world and how science tries to stop them. Her coverage of measles, which has no specific antiviral treatment, looks at why even promising drug candidates face practical barriers to reaching patients once cases spike. Across recent pieces, she returns to pathogens that linger in the body or environment in unexpected ways, such as work showing that a new Ebola outbreak in Guinea was most likely triggered by a person infected years earlier rather than a fresh jump from animals. She has also reported on studies tying climate-driven heat and drought to rising antibiotic resistance in soils and water, underscoring how environmental change feeds back into human health.

Within this infectious disease lane, she tends to build stories around the scientific mechanism and then translate that into real-world stakes. When she writes about how climate change concentrates antibiotics in drying soils and selects for resistant bacteria, she stays close to experimental details — where samples came from, how resistance was measured — but always circles back to what this might mean for future infections and treatment options. Her background in microbiology shows in the way she explains concepts like viral latency, mutation rates and host–pathogen interactions in plain language while preserving nuance.

Equity, representation and who health science serves

A second thread running through her work is attention to who is included, or excluded, in health research and care. She has profiled efforts to bring more Black participants into genetic datasets, highlighting how decades of over-reliance on people of European ancestry skews what is known about disease risk and drug response. In that reporting, she dwells not just on the statistics but on the structural reasons behind them — mistrust, access barriers, and how study design choices ripple into unequal health outcomes.

That perspective surfaces in other stories where she tracks how policy decisions, economic constraints or historic neglect shape vulnerability to disease. When she covers outbreaks or new findings in virology, she often pulls in whose communities are most affected and what researchers and public health officials are doing, or failing to do, to reach them. The result is health coverage that treats equity as a core part of the science beat, not an add-on.

Translating complex studies for different audiences

Garcia de Jesús writes both for Science News and for Science News Explores, adapting the same research base for general and younger readers. In the magazine, she handles dense primary literature — for example, genomic analyses that link present-day Ebola cases to viruses from the 2013–2016 outbreak, or global surveys tying temperature trends to resistance genes — and unpacks the methods and caveats without jargon. She uses specific details, such as mutation counts between viral strains or how drought alters antibiotic concentrations, to ground otherwise abstract risk.

In her Science News Explores work, she retools similar themes into accessible narratives, explaining how microbes live, spread and evolve in ways that middle-school readers can follow. Even there, she keeps the scientific backbone intact, using clear metaphors and stepwise explanations instead of oversimplifying or skipping mechanisms. That cross-audience practice gives her a distinctive style: she favors short, concrete sentences, defines terms briskly and lets scientists’ findings drive the story rather than opinion.

Background and approach

Garcia de Jesús has formal training in microbiology, including a Ph.D. focused on virus–host interactions, and additional training in science communication. She brings that lab experience into her reporting by interrogating study design, sample sizes and limitations before presenting results as news. Across her health coverage, she is most interested in the junction where basic microbiology meets public consequence: how a mutation pattern signals a hidden reservoir, how climate pressures reshape microbial communities, or how gaps in genetic data translate into blind spots in care.

Her stories are evidence-led, tightly sourced and anchored in current peer-reviewed work, but they are framed around questions non-specialists face, such as whether treatments exist, why some communities are left out of datasets, or how changing weather might influence the spread of resistant infections. That combination of microbial depth, equity awareness and explanatory clarity distinguishes her reporting from more general health news coverage.
