It may cause respiratory disease resembling human influenza on its own, or it may be part of a bovine respiratory disease (BRD) complex with other pathogens during co-infection. BRD is a concern for the cattle industry, so influenza D virus' possible involvement in BRD has led to research on vaccines for cattle that can provide protection ...

They are usually heard only with a stethoscope ("on auscultation"). Pulmonary crackles are abnormal breath sounds that were formerly referred to as rales. [2]

Resonance: Loud and low pitched. Normal lung sound. [15] Dullness: Medium intensity and pitch. Experienced with fluid. [14] A dull, muffled sound may replace resonance in conditions like pneumonia or hemothorax. Hyper-resonance: Very loud, very low pitch, and longer in duration. Abnormal. [14] Hyper-resonance can result from asthma or emphysema
Technically, you can’t kill the flu. “The flu virus, like all viruses, is not alive, so it can’t be killed,” says infectious disease expert Amesh A. Adalja, M.D., senior scholar at the ...
