Compared with the[ <u>**June edition**</u>](https://www.metaculus.com/notebooks/44170/respiratory-outlook-june-update/), predictions this month show: * Forecasters now expect 140[<u> confirmed animal cases</u>](https://www.metaculus.com/questions/43869/how-many-screwworm-animal-cases-will-there-be-in-the-us-before-2026/) of NWS this year, though estimates are climbing as detections spread. They anticipate slowed spread with increased USDA containment efforts, including sterile insect releases. * The Bundibugyo Ebola outbreak in eastern DRC has passed [<u>2073 confirmed cases</u>](https://www.who.int/emergencies/disease-outbreak-news/item/2026-DON607), with forecasters putting the eventual outbreak size over [<u>15,000</u>](https://www.metaculus.com/questions/43726/how-many-confirmed-cases-in-the-2026-ebola-outbreak/) as the outbreak appears largely uncontained. They give just a [<u>10% chance</u>](https://www.metaculus.com/questions/43606/ebola-bundibugyo-case-first-confirmed-on-us-soil-before-2027/) of a case first confirmed on US soil before 2027, citing limited travel between current outbreak zones, but with an eye on the cities where the virus may spread. * Measles case estimates are maintained at [<u>3,462</u>](https://www.metaculus.com/questions/42089/of-us-measles-cases-in-2026/) with[ <u>confirmed cases now at 2,231</u>](https://www.cdc.gov/measles/data-research/index.html) in the typically slow summer months.

The MV *Hondius* outbreak is [<u>over</u>](https://www.metaculus.com/questions/43461/5-non-ship-cases-linked-to-the-hondius-outbreak-before-aug-2026/), confirming forecasters’ consistently low projections around the disease. Clade I Mpox is expected to reach [<u>39 US cases</u>](https://www.metaculus.com/questions/42530/of-us-clade-i-mpox-cases-before-2027/) by year-end, amid uncertainty due to CDC surveillance issues. ## [**Read the full report**](https://www.metaculus.com/files/Respiratory-Outlook-Update-July-2026) ## [**Share your forecasts**](https://www.metaculus.com/tournament/respiratory-outlook-25-26/)
