Answer:
When a new disease first emerges, most of us lack the natural immunity to fight it off. This can cause a sudden, sometimes rapid, spread of the disease between people, across communities, and around the world. Without a natural immunity to fight off an illness, many people can become sick as it spreads.
The WHO is responsible for announcing the emergence of a new pandemic based on how the spread of the disease fits into the following 6 phasesTrusted Source:
Phase 1. Viruses circulating among animal populations haven’t been shown to transmit to human beings. They’re not considered a threat and there’s little risk of a pandemic.
Phase 2. A new animal virus circulating among animal populations has been shown to transmit to human beings. This new virus is considered a threat and signals the potential risk of a pandemic.
Phase 3. The animal virus has caused disease in a small cluster of human beings through animal to human transmission. However, human to human transmission is too low to cause community outbreaks. This means that the virus places humans at risk but is unlikely to cause a pandemic.
Phase 4. There has been human-to-human transmission of the new virus in considerable enough numbers to lead to community outbreaks. This kind of transmission among humans signals a high risk of a pandemic developing.
Phase 5. There has been transmission of the new virus in at least two countries within the WHO regionTrusted Source. Even though only two countries have been affected by the new virus at this point, a global pandemic is inevitable.
Phase 6. There has been transmission of the new virus in at least one additional country within the WHO region. This is known as the pandemic phase and signals that a global pandemic is currently occurring.
