Viruses we track

Profiles of pathogens with significant outbreak or pandemic potential.

Hantavirus

High

A family of viruses spread mainly by rodents that can cause severe pulmonary and renal syndromes in humans.

Transmission · Rodent droppings, urine, saliva

Ebola

Critical

A severe hemorrhagic fever with high case-fatality rates, requiring strict isolation and barrier nursing protocols.

Transmission · Direct contact with body fluids

Avian Influenza (H5N1)

High

A zoonotic respiratory virus with pandemic potential; surveillance and biosecurity in poultry are critical.

Transmission · Infected poultry and wild birds

Nipah

Critical

An emerging henipavirus causing encephalitis and respiratory illness, with frequent person-to-person spread in outbreaks.

Transmission · Fruit bats, pigs, contaminated food

Three pillars of the fight

Stopping a virus is never a single intervention. It is a layered system.

Surveillance

Track outbreaks, monitor reservoirs, and detect spillover events before they escalate.

Prevention

Vector control, vaccination, hygiene, and public-health communication to break transmission chains.

Response

Coordinated isolation, contact tracing, treatment protocols, and rapid-deployment field teams.

In an outbreak, hours matter. Information saves lives.
