Philippines health officials are advising the public against the practice of “tuob”, or steam inhalation for the treatment of COVID-19 as it can be harmful.
DOH Undersecretary Dr. Maria Rosario Vergeire said there is no scientific evidence proving that inhalation of steam with salt, lemon, and other ingredients could prevent COVID-19 infection, in fact steam inhalation can increase nasal secretions that can be spread through coughing or sneezing and can cause steam burns.
In addition, global health agencies like the US CDC and the WHO deny the effectiveness of this technique.
According to the DOH, wearing face masks, frequent and proper handwashing, observing physical distancing, and practice of proper cough etiquette remain the best measures to prevent the spread of Covid-19.
Through Sunday, the Philippines has reported 35,455 total COVID-19 cases and 1244 deaths. Data from World Health Organization (WHO) showed that the Philippines has the fastest-growing number of new COVID-19 cases among over 22 countries in Western Pacific Region.
