According to the CDC, the strain of Mpox that is circulating now is called the West African strain and it is rarely fatal. Most people survive Mpox if they have this strain but people with weakened immune systems, children younger than 8 years old, people with a history of eczema, or who are pregnant or breastfeeding are more likely to have serious illness or die.
While the West African strain is rarely fatal, the symptoms can be very painful and some people might have permanent scars from the rash.
