Local Thermotherapy for Patients With Mild-to-moderate COVID-19

Considering the nature of the causative agent of COVID-19, a (+)ssRNA virus, the investigators propose the use of thermotherapy as a modality for viral containment, thereby preventing the progression of the infection to severe cases. The investigators consider applying the intervention with thermotherapy mainly as an adjuvant therapy in high-risk patients. The most accessible thermotherapy delivery method the investigators have identified is the use of an electric chest pad for its wide and known clinical use, including its recommended use for patients with arthritis. The intensity of temperature delivered by the electric cushion should be placed on the first level (lowest level), to avoid discomfort to the patient. The electric cushion provides a continuous hour of regulated heat, with enough penetration to raise the external temperature of the area to 40-42 ° C, a temperature range at which facilitation of elimination of the virus is expected.
