Some members of the Nipah Encephalitis Team.
Triumph Over Nipah Virus Encephalitis
In the crucible of Malaysia's financial crisis in 1998 emerged an unforeseen adversary – a mysterious disease spreading like wildfire from pig farms in Perak to the States of Negeri Sembilan and Selangor. It struck down young, healthy men with fever and delirium, casting a pall over entire villages. Abandoned homes, army interventions and the decimation of livestock characterised the chaos. Amid this, a team from the University of Malaya's Faculty of Medicine, led by Professor Dr Tan Chong Tin, rose to confront this enigma.

Unravelling the Mystery and Pandemic Control
Initially thought to be Japanese Encephalitis (JE), efforts were directed towards controlling JE's spread from pigs to humans. However, disparities in symptoms and the disease's pattern raised suspicions. The team, undaunted by prevailing opinions, sought permission to examine victims' bodies, leading to the discovery of a novel virus—Nipah.
lThe Nipah investigation progressed as the team identified large Pteropus fruit bats as the virus reservoir. The El Niño weather phenomenon, pushing bats to pig farms, facilitated transmission. Hospitals, grappling with Nipah-infected patients, saw the team's collective efforts in managing cases, conducting studies and formulating preventive measures.
With the virus identified, strategies evolved, halting the epidemic by culling pigs and ceasing vaccinations. Ribavirin treatment proved successful, reducing mortality rates. The meticulous observations and research, published in prestigious journals, showcased Malaysia's triumph over the unknown.

Ongoing Challenges and Global Medical Impact
The Nipah Virus Encephalitis Investigation Team's accomplishments reverberated globally. Their knowledge aided in addressing Nipah outbreaks in Bangladesh and India. Invitations from the World Health Organisation underscored their expertise, emphasising the emergence of Nipah encephalitis as a global concern.
The Nipah Virus Encephalitis Investigation Team's fearless dedication and selfless pursuit of knowledge amidst danger illuminated Malaysia's medical prowess. Malaysia, through an all-Malaysian team, contributed significantly to global medical knowledge, showcasing the nation's resilience and expertise in combating emerging diseases.
