I'll have to pull up the tweet / article but not all people showing symptoms are being tested for it
They type a lot of Influenza A but additional testing for the H5 subtype is rare and I don't even know the criteria.
See the CDC weekly flu surveillance here: Weekly US Influenza Surveillance Report: Key Updates for Week 52, ending December 28, 2024
Out of 11k flu A samples typed this season only 77 were typed as H5N1 so far....
| Week 52 | Data Cumulative since September 29, 2024 (Week 40) | |
|---|---|---|
| No. of specimens tested | 1,731 | 25,214 |
| No. of positive specimens | 1,254 | 11,292 |
| Positive specimens by type/subtype | ||
| Influenza A | 1,234 (98.4%) | 10,906 (96.6%) |
| Subtyping Performed | 823 (66.7%) | 9,374 (86.0%) |
| (H1N1)pdm09 | 335 (40.7%) | 4,137 (44.2%) |
| H3N2 | 488 (59.3%) | 5,160 (55.0%) |

*This data reflects specimens tested and the number determined to be positive for influenza viruses at the public health labs (specimens tested is not the same as cases). It does not reflect specimens tested only at CDC and could include more than one specimen tested per person. The guidance for influenza A(H5) testing recommends testing both a conjunctival and respiratory swab for people with conjunctivitis which has resulted in more specimens testing positive for influenza A(H5) than the number of human H5 cases. For more information on the number of people infected with A(H5), please visit the "How CDC is monitoring influenza data among people to better understand the current avian influenza A (H5N1) situation"
