BAGUIO CITY, Philippines — As the rainy season commences, health authorities in Baguio aAre sounding a critical alarm against Invasive Meningococcal Disease (IMD), a rare but exceptionally aggressive bacterial infection that can turn fatal within 24 hours.

Experts are urgently advising parents to seek immediate medical attention at the first sign of symptoms, recalling a significant outbreak that swept through the Cordillera region in late 2004 to 2005.

Dr. Maria Lourdes Trajano, a Baguio-based pediatric neurologist, underscored the alarming speed of IMD’s progression. “It can progress rapidly and become fatal within just 24 hours,” she emphasized, highlighting the critical need for prompt medical intervention.

Trajano explained that IMD is caused by the Neisseria meningitidis bacteria, transmitted through respiratory droplets from coughing, sneezing, or close contact. Once the bacteria enters the body, it can lead to severe complications, including sepsis (blood poisoning) or meningitis (inflammation of the brain). 

According to health authorities, common symptoms of IMD include fever, headache, stiff neck, nausea, vomiting and a distinctive rash. Other concerning signs may include lethargy, irritability, muscle pain, cold extremities and rapid breathing.

The Philippines grapples with the highest meningococcal fatality rate among its neighboring countries, with up to one in two patients succumbing to the disease.

Beyond the immediate threat to life, IMD survivors often face severe, long-term complications such as hearing loss, learning delays, or physical disabilities that can significantly impede their growth, learning, and overall quality of life.

Trajano, a Medical Specialist at the Baguio General Hospital and Medical Center, reiterated the grave consequences of delayed treatment. “Because of its onset flu-like symptoms, parents may not immediately recognize that their child is in danger — until it’s too late,” she cautioned.
