Coronavirus update: 40% cases in Italian town showed no symptoms prompting mass testing

“This testing and tracing approach has had a tremendous impact on the course of the epidemic in Veneto compared to other Italian regions, and serves as a model for suppressing transmission and limiting the virus’ substantial public health, economic and societal burden,” added Crisanti.

As well as identifying the proportion of asymptomatic cases, the Italian researchers also found that asymptomatic people had a similar viral load as symptomatic patients.

Their viral load also appeared to decrease in those who had no symptoms to begin with but later developed symptoms.

This suggests that asymptomatic and pre-symptomatic transmission could contribute significantly to the spread of the deadly virus.

Thereby strengthening the notion of how important testing and isolating is to control outbreaks across the world.
