-     If someone in your vicinity is suspected or confirmed to have Nipah Virus infection, minimize close contact, and follow recommended infection control measures.

-     Use appropriate personal protective equipment (PPE) if caring for infected individuals.

 

5.       Use Protective Gear

When handling potentially infected animals or their products, use appropriate protective gear such as gloves and masks.

 

6.       Quarantine Measures

During outbreaks, adhere to quarantine measures and restrictions imposed by health authorities.
