Introduction
Infectious diseases are a major threat to human health in the current world. Especially emerging viral diseases are posing a serious risk to public health. One such dangerous and deadly disease is Nipah Virus Infection. This virus has repeatedly caused outbreaks in various countries of South Asia, including Bangladesh, and it is a matter of special concern as the mortality rate is very high. HRTD Medical Institute, as a renowned medical and diagnostic training institute in Dhaka, is presenting this article with the aim of increasing public awareness and spreading correct medical knowledge. Here, the origin, transmission mode, symptoms, diagnosis, treatment, prevention and its impact on public health of Nipah virus are discussed in detail.
What is Nipah Virus?
Nipah Virus (NiV) is a zoonotic virus, meaning it is transmitted from animals to humans. This virus belongs to the Paramyxoviridae family and belongs to the Henipavirus genus.
Nipah virus mainly causes:
High fever
Difficulty breathing
Encephalitis
Unconsciousness
Can even cause death
The mortality rate of this disease ranges from 40% to 75%, making it one of the most dangerous viruses in the world.
History of Nipah virus
Nipah virus was first identified in Malaysia in 1998–1999. At that time, an unknown encephalitis disease was seen in people associated with pig farms. Later studies revealed that it was a new virus, which was named Nipah virus—after the name of the area called Sungai Nipah in Malaysia.
Later outbreaks of this virus were seen in:
Bangladesh
India (West Bengal and Kerala)
Especially in Bangladesh, Nipah virus has shown a tendency to be transmitted from person to person, which makes it more dangerous.
Nipah virus outbreak and spread
Global situation
Nipah virus is mainly seen in:
Bangladesh
India
Malaysia (in the past)
Singapore (related to the Malaysian outbreak)
Nipah virus in Bangladesh
In Bangladesh, isolated cases of Nipah virus are reported almost every year. The main reasons for this are:
Drinking raw date palm juice
Close coexistence with bats
Lack of awareness in rural areas
HRTD Medical Institute emphasizes on educational training about Nipah virus in Bangladesh.
Natural reservoir of Nipah virus
The main natural reservoir of Nipah virus is:
Fruit-eating bats (Pteropus species)
Although these bats are not sick themselves, they can spread the virus through:
Saliva
Urine
Feces
.
Routes of Nipah virus infection
- Animal to human transmission
Eating bat-eaten fruit
Drinking raw date juice contaminated by bats
Contact with infected animals - Human to human transmission
Being in close proximity to the patient
Coughing or sneezing
Contact with body fluids - Hospital-based transmission
Non-use of PPE
Lack of proper infection control measures
This is why HRTD Medical Institute places great importance on infection control and biosafety training for healthcare workers.
Pathogenesis of Nipah virus
After Nipah virus enters the body:
First causes respiratory tract infection
Attacks cells inside the blood vessels
Crosses the blood-brain barrier
Causes inflammation in the brain
Results in:
Acute encephalitis
Respiratory failure
Multiple organ failure
Symptoms of Nipah virus
Incubation period
Usually 4–14 days
Sometimes up to 45 days
Initial symptoms
Fever
Headache
Body aches
Vomiting
Respiratory symptoms
Cough
Shortness of breath
Pulmonary infection
Neurological symptoms
Dizziness
Seizures
Unconsciousness
Coma
Diagnosis of Nipah virus
Advanced lab facilities are required for diagnosis of Nipah virus.
Tests
RT-PCR (Most Reliable)
ELISA (IgM, IgG)
Virus Isolation (High Biosafety Lab)
Specimen
Blood
CSF
Gallar Swab
Urine
HRTD Medical Institute provides modern diagnostic concepts to Pathology and Lab students.
