Possible dark mold reported inside San Mateo, Rizal health center

Several commenters questioned whether employees and patients could be exposed to the apparent mold, particularly children and older adults who may be more vulnerable to respiratory problems.

The US Centers for Disease Control and Prevention says damp and moldy indoor environments can cause or worsen respiratory symptoms, including coughing, wheezing, nasal irritation, and asthma symptoms.

Mold growth is commonly associated with moisture problems such as roof leaks, water damage, and high humidity. Removing visible mold alone may not solve the problem if the underlying source remains.

The CDC also notes that people with asthma, allergies, or certain other respiratory conditions can be more sensitive to mold, while people with weakened immune systems face a higher risk of serious mold-related infections.

That is particularly relevant in a healthcare facility, where employees spend extended periods inside, and patients seeking care may already have health conditions that make them more vulnerable. The irony is hard to miss: people going to a health center for treatment should not have to worry that the facility itself could expose them to another health hazard.

The Department of Health guidelines also require adequate ventilation in healthcare facilities, with general ward rooms required to have at least 60 liters per second of airflow per patient.

The online posts have prompted calls for the facility to inspect the ceiling, identify the source of moisture, and address the apparent mold before it becomes a larger indoor air quality concern.

radar Business had reached out to the San Mateo Rizal Municipal Health Office for comment, but had not received a response regarding the reported condition as of publishing time.
