It can also be transmitted through contaminated food and, in some cases, directly from person to person.In humans, Nipah infection can range from asymptomatic illness to severe respiratory disease and fatal encephalitis (brain inflammation). The virus can also infect animals such as pigs, causing significant economic losses for farmers.Although only a limited number of outbreaks have been reported in Asia, the virus is known for its high fatality rate and potential to cause severe disease.How Does Nipah Spread?Animal-to-Human Transmission: During the first recognized outbreak in Malaysia, which also affected Singapore, most human infections were linked to direct contact with infected pigs or their contaminated tissues. Transmission was believed to occur through exposure to respiratory secretions or bodily fluids of infected animals.Bat-Contaminated Food: In later outbreaks in Bangladesh and India, the most likely source of infection was the consumption of fruits or fruit products—particularly raw date palm sap—contaminated by saliva or urine from infected fruit bats.Human-to-Human Transmission: Human-to-human transmission has also been documented, particularly among family members and healthcare workers caring for infected patients.Nipah Virus: Symptoms Symptoms of Nipah virus infection may include:FeverHeadacheBreathing difficultiesCough and sore throatDiarrheaVomitingMuscle painSevere weaknessDizzinessAltered consciousness in severe casesEncephalitis (brain inflammation)Why Is Nipah A Concern?Nipah virus is considered a major public health threat because of its high mortality rate, ability to spread through close contact, and the absence of a specific antiviral treatment or approved vaccine for widespread use.Early detection, isolation of suspected cases, contact tracing, and strict infection-control measures remain the most effective tools for preventing outbreaks.
