According to sources, Mohammedali began exhibiting signs of the an infection on August 22. The virus may have entered his physique at the least 5 or 6 days earlier than this. Attempts are being made to trace his journey paths in the course of the interval. With the assistance of the police, the cell phone tower places will likely be recognized. A workforce of well being staff will go to all these locations to discover out the probabilities of an infection.

Local residents have mentioned that Mohammedali had a behavior of visiting the yard of a household property the place there are fruit vegetation and the presence of bats, the pure reservoir of the virus.

No suspicious deaths

Senior officers say that there have been no stories of suspicious deaths in his household or environment in latest days. That means he’s unlikely to have gotten the an infection from some others. Based on this info, the division got here to the conclusion that Mohammedali is the index patient, or the primary one from whom all others received contaminated. Also, there’s a cluster of an infection at his residence. His nine-year-old son and 24-year-old brother-in-law have been contaminated.

Including Ayancheri native M. Haris, who died on September 11, a complete of 5 individuals have contracted the virus from Mohammedali.

Also, to verify the conclusion, the division has proposed a genomic sequencing, a laboratory process to decide the order of bases in the genome of an organism in one course of, of the virus current in Mohammedali and Haris. All the organisms have a singular genome composed of nucleotide bases. If they’ve the identical sample, meaning the source of the an infection is similar. The process, nonetheless, needs to be performed at a bio-safety level-IV requirements lab. Since the State doesn’t have the experience or the power to accomplish that, the Indian Council of Medical Research-National Institute of Virology, Pune, could also be requested to do the job.

Similar episodes

In the earlier Nipah episodes in Kerala, it was concluded that fruit-eating bats are the source of the an infection primarily based on comparable episodes from different nations and States and following detection of the presence of the virus in bats collected from the affected areas. It was but to be proved how the primary patient in every of these outbreaks received contaminated. The presumption was that the an infection should have occurred after the patient consumed fruits contaminated by bat saliva or by contact with its excreta.
