Celebrity hairstylist Jesus Guerrero died of pneumonia and fungal infection, likely complications from AIDS

Jesus Guerrero, a hairstylist known for working with clients such as Kylie Jenner and Jennifer Lopez, died of pneumonia and a fungal infection, according to the County of Los Angeles Medical Examiner, likely complications from AIDS.

Jesus Guerrero, the celebrity hairstylist who died in February and was known for working with clients such as Kylie Jenner, Jennifer Lopez and Katy Perry, died of pneumonia and a fungal infection, according to the Los Angeles County medical examiner, most likely complications from AIDS.

The medical examiner's office listed Guerrero's primary cause of death as pneumonia and disseminated cryptococcus neoformans — or a fungal infection — with acquired immunodeficiency syndrome listed as the secondary cause of death.

Pneumocystis jirovecii pneumonia, the kind Guerrero was listed as having, is a particularly severe kind of pneumonia that is typically seen in people with weak immune systems, making the AIDS diagnosis likely to be a contributing factor.

Both are classified as Opportunistic Infections, meaning they are more common and more severe in people with weak immune systems.

Guerrero's family announced his death on Instagram on Feb. 23.
