Significance of Latent infection
Latent infection is characterized by its dormant state, where the virus or bacteria remains inactive within the host's body. This condition can be identified by the presence of IgG antibodies and typically does not produce infectious particles or show overt symptoms. An example of latent infection is seen with Mycobacterium tuberculosis, which can remain dormant and become reactivated under specific circumstances. Overall, latent infections pose a unique challenge as they can go unnoticed even though they have the potential to reactivate.
