Viral Respiratory Infection in Lungs - Medical Illustration #3748077 (License: Personal Use)

This medical illustration depicts a pair of human lungs, with the left lung containing two stylized green virus particles-each with spike proteins and internal nucleic acid structures-indicating active infection. The right lung remains uninfected, providing contrast to emphasize localized pathogen impact. The trachea and bronchial bifurcation are shown in pink for anatomical context.

Commonly used on health education websites, telemedicine platforms, or public health campaigns to visually explain how respiratory viruses such as influenza, RSV, or SARS-CoV-2 invade lung tissue. Matches user intent for understanding symptoms, transmission, or pathology of viral pneumonia.
