New Delhi: Amid considerations over two Indian nationals reportedly contaminated with the hantavirus aboard a cruise ship, Director of the ICMR’s Nationwide Institute of Virology Dr Naveen Kumar on Friday mentioned the circumstances seem like remoted ones and there’s no immediate public health threat to India.
Kumar mentioned there’s no proof of neighborhood unfold as of now.
Hantaviruses are primarily transmitted to people via contact with contaminated rodents or their excreta corresponding to saliva, urine and faeces, he informed PTI.
Individuals often get contaminated by inhaling aerosolised virus particles from rodent urine, droppings, or saliva in closed or poorly ventilated areas corresponding to warehouses, ships, barns and storage areas, he mentioned.

In line with the World Health Organisation (WHO), the 2 Indian passengers had been amongst a small cluster of suspected infections recognized aboard the vessel, and health authorities had been monitoring contacts and enterprise precautionary measures.
WHO officers famous that hantavirus infections are uncommon and are usually linked to rodent publicity fairly than sustained human transmission.
Kumar harassed that in contrast to COVID-19, hantavirus doesn’t unfold simply amongst individuals.
“Human-to-human transmission is extraordinarily unusual. Most hantaviruses, particularly these reported in Asia and Europe, don’t unfold between people. Restricted person-to-person transmission has solely been documented with some South American strains corresponding to Andes virus,” he defined.
WHO Director Basic Dr Tedros Adhanom Ghebreyesus, who briefed the media on the virus, mentioned “whereas this can be a critical incident, WHO assesses the publich health danger as low”.

On India’s preparedness, Kumar mentioned the nation has satisfactory laboratory surveillance capability to determine suspected circumstances.
“India has diagnostic capability for hantavirus an infection via the ICMR-Nationwide Institute of Virology and the nationwide Viral Analysis and Diagnostic Laboratory Community of 165 labs, the place RT-PCR amenities can be found for affirmation of suspected circumstances,” he mentioned.
In line with Kumar, signs usually seem one to 5 weeks after publicity and initially resemble flu-like sickness.
“Frequent warning indicators embrace sudden fever, extreme physique ache, headache, fatigue, chills, nausea, vomiting, belly ache and dry cough,” he mentioned.

“Local weather change, flooding, unplanned urbanisation, poor waste administration and elevated human encroachment into rodent habitats can increase the danger of rodent-borne infections,” he mentioned.
“Heavy rainfall and floods typically enhance rodent inhabitants motion into human dwellings and storage areas, rising publicity danger. Fast city progress with poor sanitation can additional help rodent proliferation,” Kumar added.
He, nevertheless, underlined there’s at the moment no indication of widespread transmission linked to the cruise ship circumstances and that normal rodent-control and sanitation measures stay the important thing preventive methods towards hantavirus. PTI
