Disease trends, dashboards, surveillance reports, and epidemiology updates from trusted health agencies.
CDC’s respiratory virus “activity levels” (based on emergency department data) and wastewater monitoring both aim to show whether viruses are circulating more than usual. Here’s how families and schools can use those signals this week—calmly and practically.
CDC’s weekly wastewater “viral activity levels” (very low, low, moderate, high, very high) help describe community virus activity for COVID-19, flu, and RSV. Here’s what “very low” or “low” generally means—and the practical prevention steps families can keep doing.
A rise in CDC wastewater monitoring for SARS‑CoV‑2 is an early “signal” that more virus may be circulating locally. It can’t identify individuals or diagnose anyone—but it can help families and schools plan everyday steps to reduce spread over the next days and weeks.
CDC’s national wastewater dashboard updates every Friday. Learn what “wastewater viral activity” means, what it can’t tell you about individuals, and how families can use the signal to plan everyday prevention and keep vaccines up to date.
FDA has advised manufacturers to use an updated, monovalent 2026–2027 COVID-19 vaccine formula targeting a JN.1-lineage variant called XFG for use in fall 2026. Here’s what that “strain/formula” decision does—and what stays the same—plus practical steps for families using CDC’s risk-based vaccine guidance.
A measles detection on CDC’s wastewater page is a community-level warning sign, not a diagnosis. Here’s how to read it, what it does not prove, and the practical steps families can take now.
CDC’s confirmed U.S. measles count topped 2,000 in 2026. If you get an exposure notice from a school, child care center, or workplace, the most useful next steps are to check written vaccine records quickly, follow local instructions, and call ahead if symptoms start.
A measles signal in wastewater is an early community warning, not proof your household was exposed. Here’s what current CDC data means and what families can do now.
CDC says 2026 measles cases are still climbing, and most are tied to outbreaks. Here’s what the latest data means for families, schools, workplaces, and communities—and why vaccination coverage still matters.
CDC’s latest respiratory dashboards show very low national COVID-19, flu, and RSV activity, but the bigger public-health story is how wastewater monitoring can give communities an early signal that something is changing. New CDC and journal reports also show how measles detections in wastewater can help health officials investigate sooner, even before clinical cases are confirmed.
CDC’s latest surveillance update shows measles is still spreading in the United States through multiple outbreaks, not fading into the background. The data do not mean most Americans are at immediate risk, but they do show why vaccination status, quick reporting, and early isolation still matter for families, schools, and workplaces.
CDC’s latest respiratory dashboard shows a quiet late-season national picture: COVID-19 is low, flu is declining, and overall respiratory illness activity is very low. RSV is the main exception, because it started later than expected and may still linger in some regions into May.
CDC’s 2026 measles surveillance shows the disease is still spreading in U.S. outbreaks, not just isolated cases. That matters for families, schools, and workplaces because measles spreads very easily indoors, and even small gaps in vaccination coverage can leave communities vulnerable. The latest national count is still changing as health departments investigate and report new cases. Here’s what the numbers show, why school vaccination levels matter, and what readers can do after a possible exposure.
CDC is now posting weekly measles wastewater detections. Here is what a positive signal can mean, what it cannot tell you, and what families should do now.
New CDC data show seasonal allergies affect about 1 in 4 U.S. adults and 1 in 5 children. Here’s how to spot them, treat symptoms, and know when to get care.
The latest CDC outbreak data point to an active 2025–2026 norovirus season, with an early fall rise and a peak in early February. But the numbers do not show the biggest weekly spikes seen in the historical comparison. Here’s what the data do and do not mean, plus the prevention steps that matter most at home, school, work, and around food.
CDC says an H5 signal in wastewater can be an early warning worth investigating, but it cannot show whether the source is humans, animals, or animal products such as milk. That means a dot on the map does not by itself prove human cases or community spread, and CDC said on April 3, 2026, that current flu surveillance still showed no indicators of unusual influenza activity in people, including avian influenza A(H5).

CDC’s April 3, 2026 H5 update says there are still no signs of unusual flu activity in people. Here is what 71 U.S. cases do and do not mean, and why worker monitoring still matters.
A new federal hazard alert puts fresh attention on a serious worker-health problem in countertop fabrication: inhaling fine silica dust from engineered stone. Here is what the warning says, what California’s cases show, what symptoms matter, and why a new bill in Congress could affect legal accountability without changing the medical risk.
Measles detection is getting faster in 2026 through wastewater signals, travel-linked investigations, and county-level tracking. Here is what those tools can do, what they cannot do, and what families should do now.
New 2026 U.S. colorectal cancer statistics show a split trend: rates keep falling in many older adults but are rising in younger adults. Here is what that means for symptoms, screening at 45, family history, and why access still matters.
New CDC data show the 2025-26 flu shot was a weaker match against drifted viruses, but it still lowered the odds of doctor visits and hospitalization. Here’s what happened, who should seek treatment quickly, and what is changing for next season.
