Nipah Virus in India – Latest News 2023

In 2023, the Indian state of Kerala is grappling with the fourth outbreak of Nipah Virus (NiV), resulting in two deaths on August 30th and September 11th. This outbreak is centered in the Kozhikode district, where authorities have implemented containment measures. Several cases are currently confirmed.

What is Nipah Virus?

Nipah virus is a disease that can spread from animals to humans. Its identification was first made in 1999 among pig farmers in Malaysia. Since then, outbreaks have occurred in several countries, including India, Bangladesh, Singapore, the Philippines, and now Kerala. The virus can spread through direct contact with infected animals like bats and pigs or their bodily fluids. It can also spread through contaminated food or from one person to another.

Current Nipah Virus Strain in Kerala

The present strain in Kerala is being considered a Bangladesh variant. While it is considered less contagious, it can still transmit from human to human. Unfortunately, there is no specific medication or vaccine for treating the infection, so medical care focuses on managing symptoms and preventive measures.

Efforts to combat the outbreak involve the Indian Council of Medical Research delivering antibodies and setting up a mobile laboratory for testing samples in Kozhikode. A team of specialists has been sent to help prevent the virus’s spread. Monitoring of potentially exposed individuals, some of whom are considered at high risk, is also underway.

To prevent the virus’s spread, schools, colleges, and other educational institutions in Kozhikode have been temporarily closed. Additionally, gatherings like Friday prayers have been suspended, and people are advised against consuming toddy (an alcoholic drink) from open containers.

Kerala often reports Nipah virus outbreaks due to factors such as its forested areas, heavy monsoon rains, and urbanization, which bring animals closer to human settlements, increasing the risk of zoonotic diseases like Nipah. Climate change and migration also contribute to disease spread. Kerala’s robust surveillance system and high literacy rate have helped in early detection and management of such diseases.

Nipah Virus Lockdown Situation in Kerala

As soon as the cases of Nipah virus increased in Kerala, the state government took crucial steps to prevent its spread. These measures include temporarily closing select schools and offices and designating seven villages as restricted areas. After the unfortunate deaths of two individuals in Kozhikode due to Nipah virus, the Kerala Health Department has issued a high alert.

However, despite these stringent measures, the Kerala government has not yet announced a statewide lockdown. If the number of infections continues to rise, the possibility of a statewide lockdown is being considered. This underscores the government’s commitment to dealing with the seriousness and crisis posed by the Nipah virus outbreak in the state.

According to the latest updates, there are three active cases of Nipah virus in Kerala, and efforts are ongoing to trace their contacts. Kerala’s Health Minister Veena George has provided information about the number of identified contacts, categorized into high and low-risk individuals. The government has also established 19 surveillance committees for monitoring and management of the outbreak.

Furthermore, telemedicine services have been deployed to provide medical assistance to those in need, and the locations of deceased individuals have been disclosed to the public. High-risk individuals are advised to stay in their homes, and a dedicated call center is available for reporting symptoms. If individuals develop symptoms, they will be transferred to medical college facilities for further assessment and care.

The situation in Kerala remains dynamic, with the government actively monitoring and responding to the increasing Nipah virus outbreak to safeguard public health.

Nipah Virus Symptoms in Kerala

Like in other regions, Nipah virus infection in Kerala can manifest with various symptoms. These symptoms can vary in severity, and it’s not necessary for every person infected with the virus to exhibit all these symptoms. Symptoms of Nipah virus infection may include:

  1. Fever: Nipah virus infection often starts suddenly with a high fever, which is one of the main symptoms.
  2. Headache: Headache is a common symptom and can be severe in some cases.
  3. Muscle Pain: Infected individuals may experience muscle pain or myalgia.
  4. Vomiting: Nausea and vomiting are common symptoms and can be quite severe.
  5. Sore Throat: Throat irritation is an early symptom of Nipah virus infection.
  6. Respiratory Symptoms: Some individuals may develop respiratory symptoms like cough and difficulty breathing.
  7. Drowsiness or Confusion: As the infection progresses, individuals may experience drowsiness or confusion, and in severe cases, even coma.
  8. Seizures: In some cases, individuals may have seizures, which are abnormal electrical activities in the brain.

It’s important to note that the incubation period for Nipah virus, the time between exposure to the virus and the onset of symptoms, can vary but is typically between four to 14 days.

Since Nipah virus infection can be severe and life-threatening, anyone experiencing these symptoms and having had contact with the virus, such as contact with infected animals or individuals, should seek immediate medical help. Early diagnosis and medical care are crucial for managing the disease and improving the chances of recovery. Additionally, preventive measures to reduce the risk of virus transmission, such as avoiding contact with potentially infected animals and practicing good hygiene, are essential.

Nipah Virus in the History of Kerala

In 2018, Kerala witnessed its first outbreak of the Nipah virus, which raised alarm among healthcare officials. The virus claimed the lives of 17 out of 18 confirmed cases. It had already spread among humans before being identified, leaving the state with limited knowledge on how to handle it. During this outbreak, Kerala’s society underwent social distancing, contact tracing, and isolation, introducing new concepts.

In June 2019, another Nipah case emerged in Ernakulam, marking the second outbreak in Kerala. This consistent threat pushed the health department to work on a systematic approach. Guidelines for Nipah virus infection control were issued, covering diagnosis, monitoring, treatment, and sample collection. A resource group of senior doctors held brainstorming sessions and collaborated with the World Health Organization (WHO) to refine protocols.

In 2020, Kerala reported no Nipah cases, but the 2019 protocol was updated and integrated into the healthcare system. In 2021, amidst the COVID-19 pandemic, a 12-year-old boy in Kozhikode succumbed to Nipah. Thanks to the COVID-19 protocols, public awareness, and preparedness, the virus remained limited to a single case that year.

Over the past few years, the state has improved its capacity to detect Nipah. In 2018, confirmation came from a lab outside the state. In 2019, Kerala established its testing facilities. In 2023, Kozhikode swiftly identified Nipah with rapid testing, setting up virology labs and mobile testing units for prompt diagnosis. Drawing from past outbreaks, the state continues to manage the 2023 outbreak based on the guidelines established in 2021.

In 2023, Nipah resurfaced in Kozhikode. The Health Department responded promptly by collecting and monitoring fever data. Local testing of samples was conducted, and results were confirmed by the National Institute of Virology in Pune. The state, relying on its past experiences, continues to manage the 2023 outbreak based on the guidelines established in 2021.
