Mpox cases on the rise: Which strain is the most dangerous?

Listen to Story Mpox is a viral infection similar to smallpox. The disease has raised global alarm after the World Health Organization (WHO) declared it a health emergency, with its spread now reaching over 116 countries. Mpox, which was earlier known as monkeypox , has two primary strains that differ in their severity and geographical origins: the Central African (Congo Basin) strain and the West African strain.

Each of these strains has distinct characteristics that influence the severity of the disease and its impact on affected populations. The Central African (Congo Basin) strain, known as clade 1b, is considered the more dangerous of the two . This strain is known for its higher virulence, leading to more severe symptoms and complications.

Patients infected with the Central African strain are at greater risk of experiencing serious health issues, including a higher mortality rate.

Clade 1b causes death in about 3.6% of cases, with children more at risk, according to the WHO. In contrast, the West African strain, known as clade 2, is less severe, typically causing milder symptoms and having a lower mortality rate, usually less than 1%.
