Why Sephrus?

When evidence matters,
the time from viral exposure to illness can be just 3 days

days 0

Symptoms may appear about 3 days after exposure.
If exposure can be identified early,
response can begin before symptoms appear.

minutes 0

For a healthy person, meaningful exposure may occur
in as little as 10 minutes.
Ventilation alone is not always enough.

What we need is actionable information:
which virus is present
and when the environment requires attention.
