Going for a job interview for a job in public health? Don’t make these mistakes.

You might not get the perfect interview, but at least you won’t bomb it. — I remember my first job interview for a public health job. It was 2007, and I had just finished my master of public health (MPH) degree in epidemiology and biostatistics. My capstone project was about doing influenza surveillance in a rural setting, where the data could be more local and…

Defendiendo lo que escribo

No tengo la obligación moral de defender lo que escribo, especialmente cuando no lo escribí para ofender. — Como adulto bilingüe, he emprendido un viaje notable de autoexpresión y creatividad en inglés, mi segundo idioma.

Why are there many vaccinated kids in measles outbreaks?

As usual, the answer is in the proper analysis of data. — A Fraud and Its Victims In 1998, a team of researchers in Great Britain published a study examining the relationship between the MMR (measles, mumps, rubella) vaccine and autism. Or, as the study paper put it, “We identified associated gastrointestinal disease and developmental regression in a group of previously normal children, which was generally associated…

Does Eating Ice Cream Lead to Drowning? Not If You Understand Confounding

The data will not analyze itself. — Suppose you’re an epidemiologist at a local health department in a resort town. The town council just had a person give testimony that ice cream leads to drowning, and they have the data to prove it. They pulled 700 random records from the local ice cream shop over the last…

I’ll Debate You On Vaccines…

…But we need ground rules. — A group of entertainers and anti-vaccine activists recently tried to harass a well-known vaccine researcher into a “debate” on vaccination. Thankfully, the researcher refused to engage. So, true to form, the entertainers and anti-vaccine activists claimed victory. This is an old tactic by science deniers and others. They challenge you…

The next pandemic pathogen will surprise us, but it won’t be a surprise.

Maybe it will be influenza. Maybe tuberculosis. Maybe an old pathogenic foe. Or maybe a deliberate act from a bad actor. Whatever the scenario is, we’re not ready. — If you only have a minute, here’s the TL;DR version… I discuss the possibility of future pandemics and suggest that influenza and drug-resistant tuberculosis are among the most likely candidates for pathogens that cause a pandemic. I also discuss the potential for intentional release of smallpox and the need for pandemic preparedness. The post highlights the importance of public health…
