TikTok’s ‘Dancing Engineer’ Jainer Moises Pinedo Vargas Dead from Complications of Dengue Fever

Jainer Moises Pinedo Vargas , better known on social media as the “Dancing Engineer,” died on Sunday, August 22 due to complications from dengue fever. He was 34.

Vargas contracted the mosquito-borne disease while in Condorcanqui Province, Peru on July 21, according to Peru21 . Dengue fever is prevalent in tropical and subtropical climates, with the Mayo Clinic describing symptoms as “flu-like,” including nausea, vomiting, headaches and muscle/bone/joint pain. While most cases clear up “in a week or so,” severe cases, aptly called “severe dengue,” can be fatal.

After Vargas went to a hospital in Bagua, Peru, doctors transferred him to a larger facility in Chiclayo when they discovered fluid around his lungs. There, his condition worsened as the fluid led to respiratory arrest. Doctors soon put him on a ventilator.

When Vargas underwent testing in the ICU, doctors found he had Hodgkin’s lymphoma, which Department of Health Deputy Minister Ricardo Peña told Peru21 likely contributed to his death .
