Respiratory viruses with illness ranging from mild to severe. Explore its illustrative 3D model, human context, and sources.
This human-focused clinical group covers influenza illness rather than a single viral species. Symptoms often start suddenly. Influenza can cause mild or severe disease, and some people develop complications such as pneumonia.
Serious complications are possible. Older adults, young children, pregnant people, and people with certain chronic conditions have higher complication risk.
Original illustrative influenza A particle with a lipid envelope, distinct HA and NA surface proteins, a simplified matrix layer and eight RNA-protein complexes. The clinical profile also covers influenza B and filamentous forms; neither is reconstructed here. Protein shapes, positions, counts, colours and scale are not measured. Independent scientific review remains pending.
