How has histology advanced our knowledge of infectious diseases?

Histology has been instrumental in studying the tissue effects of infectious diseases. For instance, in viral infections like COVID-19, histological analysis of lung tissues has revealed the presence of diffuse alveolar damage and inflammatory infiltrates. These findings have improved our understanding of disease pathology and informed treatment strategies. In bacterial infections, histology can help identify the presence of bacteria and the extent of tissue damage, guiding antibiotic therapy.
