Grace has otherwise recovered from the virus. Her mother Denise Kahindo says she is still unsure how her daughter was infected earlier this month. “I just helplessly noticed the symptoms on her body,” she said.

For disease experts, Grace's case embodies a new concern about Mpox, which was first identified over 50 years ago.

Her infection was caused by a new variant that appears to be more capable of transmitting between people than previous strains.

Local doctors say they have seen 130 suspected Mpox cases, almost entirely in children and adolescents, in the last four weeks at a nearby facility that treats displaced people from the camps in the last four weeks.

“Fifty percent of the 130 cases are even less than five years old,” said Dr Pierre-Olivier Ngadjole, a medical advisor for Medair, a charity helping with treating and transporting patients from the camp near Goma to the nearby medical center in Munigi.

An estimated 750 000 people have fled to the area due to fighting between the M23 rebel group and the DRC government.

Mpox, a viral infection that can spread through close contact is usually mild but can lead to death in some cases.

It causes flu-like symptoms and pus-filled lesions on the body.

The current mpox outbreak in DRC has already seen around 27 000 cases, and claimed more than 1 100 lives, most of them children, since the beginning of 2023.

It began with the spread of an endemic strain, known as Clade I. But the new variant, known as Clade Ib, appears to spread more easily through routine close contact, as seems to be the case among children.
