Looking for real-time infectious disease trends? PopHIVE has you covered.

PopHIVE combines multiple sources of data — like Google Trends and medical records — to keep you informed in real-time. When one source slows down, others fill in the picture.

Graph of trends in respiratory viral activity in Florida shows several data sources have trends going slightly up. Sick season is starting. Here’s how to watch infectious disease trends (even when some data sources are down). Yale School of Public Health.

Activity is increasing in Florida, where RSV season often begins before sweeping across the nation. This can be an early sign that respiratory virus season is getting underway.
Graph of trends in respiratory viral activity in Florida shows several data sources have trends going slightly up. Arrow pointing to title says “PopHIVE brings together multiple data sources —from Google Trends to medical records and more— so you can still track real-time infectious disease activity even when federal data slows down.” Arrow pointing to one data source line says “Epic Cosmos is based on emergency department data (non-federal source)” Arrow pointing to another data source line says “Google Health Trends looks for searches related to COVID-19”

Flu activity is still low (for now). Graph of trends in influenza activity in the United States shows multiple data sources showing rates are low. Arrow pointing to one data source line on the graph says “Epic Cosmos (based on emergency department visits) is the most up-to-date source for flu”

COVID-19 is still trending down. Graph shows trends in COVID-19 activity in the United States. Multiple data sources show it’s trending down. The latest data from Delphi’s doctor and hospital claims

What does it mean? COVID may have created a new year-round baseline for work absences that is similar to influenza season conditions before the pandemic; policymakers should consider expanding interventions & data collection efforts to address the negative impacts of COVID-19 on the labor force. 5/

Our latest paper in @jamanetworkopen.com where we asked: Following the #COVID pandemic, has SARSCoV2 circulation been associated with health-related absences from work and labor force exits? @yaleemd.bsky.social @princetonecon.bsky.social @brookings.edu 1/ jamanetwork.com/journals/jam...

Enduring Outcomes of COVID-19 Work Absences on the US Labor Market

This cohort study examines the extent to which COVID-19 continues to generate work absences and decrease labor force participation beyond the pandemic period in the US.

Even with improved sanitation, nutrition, & treatments, people in the U.S. were still becoming infected, hospitalized, and scarred for life by the ravages of infectious diseases. Vaccines added an essential layer of protection that helped us nearly eliminate diphtheria, measles, polio, & more.

By adding a layer of treatments and tools such as ventilators, we lower the risk of death from infectious diseases. But they can’t save everyone, and they don’t prevent infectious diseases from spreading.

Nutrition is another layer of protection. Nutrient deficiencies weaken your immune system. In late 1800s/early 1900s London, improved nutrition did not correlate with the spread of infectious diseases, but did correlate with decreased severity of measles and mumps infections.

Sanitation is an important base layer. Even today, improved sanitation can reduce childhood deaths by more than half (according to studies in some countries).

Public health is like cake. Cake has layers. Public health has layers. And when we stack the layers of public health – think combining sanitation + nutrition + medical treatments + vaccines + addressing social & environmental factors that impact health – we get to enjoy more birthday cakes.
