Health advocates are intensifying calls for earlier detection of encephalitis, a fast-moving inflammation of the brain that specialists say can quickly lead to death or permanent neurological damage if not identified and treated without delay.
Ahead of World Encephalitis Day on 22 February, Encephalitis International is promoting a symptom awareness campaign centered on the acronym “FLAMES,” a recall tool designed to help the public and frontline medical workers recognize the condition before it escalates.
Medical experts describe encephalitis as a neurological emergency in which timing can determine survival and long-term recovery. Early manifestations often resemble routine viral illnesses, making misdiagnosis or delayed diagnosis common. As inflammation worsens, patients may experience severe headaches, altered consciousness, memory disturbances, behavioral or personality changes, seizures, and other life-threatening complications.
Dr. Ava Easton, chief executive of Encephalitis International, said low public awareness continues to contribute to dangerous delays in treatment. She stressed that prompt recognition of warning signs significantly improves outcomes, while missed symptoms can result in lifelong disability or fatal consequences.
Globally, encephalitis affects an estimated three people every minute. Despite this, surveys show that nearly eight in ten adults are unfamiliar with the disease. The World Health Organization has identified encephalitis as a major contributor to neurological health loss in children under five and an increasing public health concern across age groups. Though considered relatively uncommon, the illness carries a heavy disease burden because of the severe brain injury it can cause when treatment is delayed.
In the Philippines, specialists say the impact is magnified by limited access to neurologists and specialized treatment centers, particularly in rural areas. Long travel times, high medical costs, and restricted availability of essential medicines further complicate timely care. Families often shoulder prolonged caregiving responsibilities and financial strain when survivors are left with cognitive, physical, or behavioral impairments.
Historical data on Japanese encephalitis in the country illustrate the seriousness of the threat. Before routine immunization programs were strengthened, studies showed infection exposure increased with age, affecting a significant proportion of adolescents. Fatality rates in some reports exceeded 20 percent, and neurological complications were documented in a majority of survivors. Cases were observed to peak during the rainy season, especially in northern regions.
Physicians have also reported a rise in autoimmune encephalitis cases among Filipino children in hospital settings, reflecting evolving neurological risks. At the same time, heightened regional monitoring of the Nipah virus, a zoonotic infection capable of causing severe encephalitis, has reinforced the importance of preparedness and rapid symptom recognition across Asia, even in the absence of a confirmed outbreak locally.
Dr. Ferron F. Ocampo, an adult neurologist specializing in neuroinfectious diseases, said early intervention can dramatically change patient outcomes. He noted that delayed diagnosis frequently leads to preventable complications, long-term disability, or death, underscoring the need to strengthen symptom awareness both in communities and among non-specialist healthcare providers.
Organizers of World Encephalitis Day are encouraging Filipinos to learn the warning signs associated with the FLAMES campaign and to seek immediate medical attention when symptoms arise. Supporters are also being urged to wear red and share awareness messages online as part of global efforts to reduce mortality and disability linked to the disease.
Health advocates say the campaign’s central message is straightforward: encephalitis is time-critical. Faster recognition leads to quicker diagnosis, earlier treatment, and a greater chance of survival and recovery. PLS
