The State’s Zika virus (ZIKV) tally rose to 23 on Tuesday with 4 new instances being reported from scattered city locales inside the capital district.
Of the 23 ZIKV instances reported to date, three have been in pregnant ladies.
On Tuesday, a 35-year-old lady at Poonthura, a 41-year-old pregnant lady at Sasthamangalam, a 38-year-old physician at a personal hospital and a 16-year-old lady at Karikkakam had been diagnosed with the an infection. These are all samples despatched by clinicians in the town.
Geographic unfold
The incontrovertible fact that remoted instances are being reported from varied geographic factors in the district is not only worrying, however it has made the duty of epidemiologists, who’re making an attempt to hint the origin and the unfold of the outbreak, tougher. “It is more or less given that the virus would have been in circulation in the district for the past few months. It is also possible that there were several undetected cases which never reached a clinician, because ZIKV mostly manifests as a mild or asymptomatic infection which resolves itself in two or three days. We have no way of knowing the extent of the geographic spread of the disease unless new cases come up. A retrospective mapping of the infection through sero surveillance is impractical, costly and almost impossible because the Elisa antibody (IgG) test would show cross reactivity in people who had prior dengue infection. We can only look ahead and take prospective action, which includes ante-natal screening and surveillance and intensive mosquito- control measures,” an epidemiologist mentioned.
District well being officers mentioned that whereas a cluster of epidemiologically linked instances have been discovered round a personal hospital in the town, the brand new instances which have come up, must be investigated.
The metropolis Corporation has been requested to do intensive vector- management measures inside a radius of the hospital, together with spraying of larvicides in all breeding websites discovered in the development websites and fogging to kill grownup mosquitoes.
Central staff
The Central staff, which is investigating the outbreak, visited more subject websites, together with Parassala from the place the primary case was reported. They are anticipated to go to Poonthura on Wednesday.
