The pathogenicity of a virus depends on several factors:

1. Virulence: This refers to the ability of the virus to cause disease. Viruses with high virulence cause severe disease, while those with low virulence cause milder disease.

2. Host susceptibility: This refers to the ability of the host (the person or animal infected by the virus) to resist or tolerate the virus. Factors that can affect host susceptibility include age, health status, and immune system function.

3. Virus strain: Different strains of the same virus can have different levels of pathogenicity. For example, some strains of the influenza virus are more pathogenic than others.

4. Route of transmission: The way a virus is transmitted can also affect its pathogenicity. For example, viruses that are transmitted through the air (like the flu or COVID-19) can be more pathogenic than those that are transmitted through other routes.

5. Dose of virus: The amount of virus that a person is exposed to can also affect the severity of the disease. A higher dose of virus can cause more severe disease.

6. Virus replication: The ability of the virus to replicate inside the host's body can also affect its pathogenicity. Viruses that can replicate quickly and in large numbers can cause more severe disease.
