And, I can say that we are satisfied with our preparedness. We have already held three videoconferences on this matter and issued 13 advisories. The secretary (health) will soon hold video conferences with other states,“ Nadda told reporters after the meet.Secretary Mishra said Kerala is battling a multiple onslaught of dengue, malaria and other such diseases due to early arrival of monsoon.“We had already sent a team there and it has come back after assessing the situation. But, no request has come from Kerala side on this matter. The state has a robust health mechanism though,“ he said.Mishra added that many of these reported cases include suspected ones too, so the final confirmed cases tally would only come by the year end, after the season ends.According to the figures provided by the ministry, Karnataka has reported 1,945 cases, Gujarat 616, Andhra Pradesh 606 and West Bengal 469, among other states, till July 2.The number of dengue cases recorded in Delhi has touched nearly 100, with 44 of the infection cases diagnosed here being traced to other states.As many as 10,952 chikungunya cases have also been reported in the country till July 2.
