Who Counts? Data Collection & the Communities Left Out
Data and Metrics
Claire Wilkinson, MPH
Who gets counted in data shapes whose needs are seen, funded, and addressed. When you see data driving big decisions, check who is included and who is missing.

What’s a health scam?
Uncertainty and Misinformation
Clara Ke, BSN, RN

What’s going on with this U.S. childhood vaccine schedule change?
Health Policy Vaccines
The U.S. federal government recently announced big changes to the childhood vaccine schedule. It is reducing the number of vaccines “routinely” recommended for all kids and moving several vaccines into an “optional/shared decision” category instead. This means they’re only routinely recommending protection against 11 diseases, instead of 17. Those Nerdy Girls and many other public Read more…

Q: What does science say about gender identity?
Reproductive Health
Those Nerdy Girls
A: Differences in brain structure and/or function, hormone levels during different phases of development, and even genetics seem to shape our internal sense of gender identity. Sometimes these “line up” with the factors determining body anatomy, and sometimes they do not. Gender identity seems to be “hard wired” into the brain. There is no evidence Read more…

What are neglected tropical diseases, and why do they matter?
Infectious Diseases
Rebecca Raskin-Wish
Neglected tropical diseases (NTDs) are a group of bacterial and parasite related diseases. NTDs are considered “neglected” because they have often been ignored as they tend to impact those living in extreme poverty, where there is little access to safe water and healthcare. NTDs include Chagas disease; dengue and chikungunya; dracunculiasis; echinococcosis; foodborne trematodiases; human Read more…

The American Heart Association (AHA) recently suggested that light drinking may be a positive for heart health.

Should I get hepatitis C screening?
Infectious Diseases
Sarah Whitley Coles, MD
Hepatitis C is a virus spread through infected blood that can hurt the liver over time, but simple screening tests can find it early, and today’s treatments can cure most people. It’s respiratory virus season: that jolly time of year when people get Covid, flu, respiratory syncytial virus, and all the other viruses that cause Read more…

Q: What is a toilet plume?
Infection and Spread
Jennifer Beam Dowd, PhD
In our recent post on norovirus, aka stomach flu, we advised folks to “close the lid” to avoid spreading disease via toilet plumes. Here’s a deeper dive (Ewwww!) into that topic. A: A picture is worth a 1000 words. 💩 😱 TL;DR: Close the lid. Scientists have used lasers to measure aerosols (tiny water droplets) Read more…

A: Differences in brain structure and/or function, hormone levels during different phases of development, and even genetics seem to shape our internal sense of gender identity. Sometimes these “line up” with the factors determining body anatomy, and sometimes they do not. Gender identity seems to be “hard wired” into the brain. There is no evidence Read more…
What are neglected tropical diseases, and why do they matter?
Infectious Diseases
Rebecca Raskin-Wish
Neglected tropical diseases (NTDs) are a group of bacterial and parasite related diseases. NTDs are considered “neglected” because they have often been ignored as they tend to impact those living in extreme poverty, where there is little access to safe water and healthcare. NTDs include Chagas disease; dengue and chikungunya; dracunculiasis; echinococcosis; foodborne trematodiases; human Read more…

What’s with the American Heart Association’s new claims about the heart healthiness of alcohol?
General Health Health Policy
Sara Gorman, PhD, MPH
The American Heart Association (AHA) recently suggested that light drinking may be a positive for heart health. The health benefits of even moderate alcohol use seem very small while the risks are real. In July, the Association, which is a leader in the heart health field, published a review suggesting that not only is light Read more…

The Hepatitis B birth dose is no longer recommended by the CDC. This is why your baby (or you) should get it anyway.
Infectious Diseases Vaccines
Andrea Harmony, NP-C, PMHS
Hepatitis B (HepB) is an infection of the liver that can lead to chronic disease requiring lifelong treatment and an increased risk of cancer and death. The HepB vaccine has minimal risks and many benefits. Skipping the birth dose leaves infants vulnerable to a lifelong risk of chronic liver disease and cancer. This is why Read more…

It’s not too late to get your flu shot
Infectious Diseases Vaccines
Jennifer Beam Dowd, PhD
TL:DR: The flu season can linger through May, so it’s not too late to get your vaccine. If you already had the flu, the shot can still reduce your risk of catching one of the other strains (the “tri-valent” vaccine covers three). This year’s flu vaccine reduces risk of severe disease, even against the new Read more…
