Infectious Disease Spread explores how the viral network in our own bodies contributes to how infectious diseases spread person to person.


Meru is an infectious diseases epidemiologist.
Meru works in the field of infectious diseases – understanding how diseases spread – looking at patterns of spread, and design strategies that can prevent spread early on; and implement control measures as needed.



Infectious Disease Spread was inspired by Covid-19 and the heightened awareness of cleanliness, personal proximity, and the dangers our own touch presented. Listening to Meru talk she mentioned understanding how infectious diseases spread person to person, that we provide a viral network via our own bodies. It begins to be easy to imagine our own skin presenting symptoms and signs in a visually impactful way.
