ABSTRACT

Demodicosis is a skin parasitosis associated with diseases that affect the pilosebaceous unit such as Rosacea, Seborrheic Dermatitis, Pityriasis folliculorum, Folliculitis and Blepharitis. Patients with acneiform eruptions, active acne and rosacea were observed from March to November 2020 and we performed a cyanoacrylate biopsy, considering them positive with more than five Demodex per cm2. Patients from March (unconfined) acted as controls and those from April to November (confined) as the object of study. Cases were quantified and statistical analysis was performed. 743 patients were studied, 147 presented recent clinical manifestations of acneiform eruptions, active acne and rosacea, 145 biopsies were positive, the average age was 28 years (DS: 13-r: 11-71). Positive cases increased during confinement from 7% in March to 18% in April and subsequently to figures between 18 and 35%, the statistical analysis was positive from the second month of confinement and remained significant for 6 months. Conclusions: The confinement increased the cases of demodex and the infection was so symptomatic that it forced patients to go to the doctor regardless of the risk of the pandemic.
