DOH Spokesperson Undersecretary Eric Tayag, in a radio interview, provided insights into the distinctions between these two.

Diarrhea, he explained, serves as a symptom. Gastroenteritis, also recognized as infectious diarrhea, can stem from viral or bacterial origins.

Addressing treatment approaches, Tayag underscored that bacterial infections may necessitate antibiotics, whereas oral rehydration stands as the primary course of action for viral infections.

In the context of the recent diarrhea outbreak in Baguio City, Tayag emphasized the role of person-to-person contact and inadequate hand hygiene in facilitating the virus' spread. 

He advocated for vigilant handwashing practices, particularly after restroom use and before food handling. 

Immediate cleanup of vomited material is also stressed to curb the disease's further dissemination.

DOH Officer-in-Charge Assistant Secretary and Deputy Spokesperson Dr. Albert Francis E. Domingo also explained that Acute Gastroenteritis (AGE) requires a medical diagnosis by a physician. 

On the other hand, diarrhea is characterized by loose and watery stools. Domingo said it is also identified as one of the symptoms of AGE, accompanied by vomiting, abdominal pain, and fever.

Depending on the symptoms of gastroenteritis, Domingo said the treatment may vary. 

“For example, if the symptom is diarrhea, there may be antidiarrheal agents, in addition to hydration, that a doctor will prescribe for treatment,” he explained. 

Prevention of gastroenteritis, he said, includes hygiene and safe water.

Domingo stressed that prevention is "meant to stop the disease process from starting or progressing" while control refers to "efforts to stop the spread or added disease burden."
