Chikungunya cases this year enlisted a 113% ascent contrasted with 2019. Instances of dengue and jungle fever, be that as it may, declined by 92% and 87%.
Wellbeing authorities are yet to discover the explanation for the ascent of chikungunya cases. “Dengue and chikungunya both are viral infections spread by Aedes mosquito. If the mosquito density is high it would have resulted in increase in dengue cases also. We are analyzing the trend to find out the reason behind it. We are scanning the areas reporting an increase in chikungunya cases,” said Bhavin Solanki, the clinical wellbeing official.
The cases are on the ascent since August and it kept on expanding in October. In the initial 10 days of the month, the normal argument every day was six against four in September. Authorities said that complete dengue cases might be less when contrasted with the most recent year, however as of now there is a consistent ascent in cases.
The authorities said that in 2019, 13 dengue passings were accounted for against which this year there have been no passings either because of dengue or chikungunya. He said instances of jungle fever and falciparum intestinal sickness were likewise declining in the city.
“This year fewer raids were conducted against commercial establishments and construction sites because the administration was engaged more in the Covid management,” said the official.
Prof Deepak Saxena, a disease transmission specialist at IIPH-G, said that alongside Aedes aegypti, Aedes albopictus (Asian tiger mosquito) likewise go about as optional vector for the transmission of both chikungunya and dengue. “The tiger mosquito is considered to be highly competent vector for chikungunya. The virus is found replicated to high levels in the mosquito as early as two days after the ingestion of infected blood,” he said. “Circulation pattern of dengue and chikungunya are likely to be modified in the future. Co-infection of mosquitos in Ahmedabad needs study.”
Dr Sanjay Shah, head of crisis office at a city-based clinic, said that the chikungunya flare-up is a recurrent occasion and was seen around three years back in the city. “There are no specific medical reasons for less dengue and more chikungunya cases – but we believe it’s to do with the viral distribution and vector carrier,,” he stated, including that this year, the chikungunya is more extreme with patients revealing serious polyarthritis where they can’t get up from the very first moment.
“Mosquitos for malaria are found in dirty water whereas mosquitos for dengue and chikungunya prefer clean water. It’s seen more prevalent on open construction sites and stored water. While malaria mosquitos bite during night hours, Aedes aegypti are active during daytime,” said Dr Manoj Vithalani, a city-based consulting physician. “One must wear full-sleeve clothes and clear the open stored water. Compared to last year, we have seen significant rise in chikungunya cases this year. Malaria cases have been reduced perhaps due to cleanliness drives in the light of Covid-19 pandemic.”
