Udupi/Mangaluru, Mar 20: While Udupi district has recorded two confirmed H1N1 deaths in first three months of 2017, Dakshina Kannada district has recorded first death of the year in March.
Udupi district surveillance officer Dr Vasudev Upadyaya said the district has reported 58 positive cases since beginning of the year.
"Earlier we used to see 10 suspected cases per day and now it has reduced to just one or two per day,'' he said while pointing out that there is a cyclical change once in three years as far as swine flu incidences are concerned.
"Normally we used to see more cases during winter months, but this year, we are seeing people getting H1N1 in March also. Now the dry season has started, the incidences will be much less,'' he hoped.
According to officials in Dakshina Kannada, the death of a six month pregnant on March 11 is the first case of confirmed H1N1 death in the district. She had got fever on March 8 and was treated for three days.
Apart from the death of woman, 12 positive cases have been reported in Dakshina Kannada since January this year out of the 62 blood samples tested for H1N1.
Dr Rajesh, district surveillance officer, said unless patients are treated within 36 hours of initial symptoms with Tamiflu, complications or mortality rates are likely to be high, he said.
Dr Rajesh said that the peculiar weather pattern may be one of the causes for the rise in cases. Dakshina Kannada district had recorded its very first H1N1 death in March 2015 with a 62-year-old person succumbing to the flu.
