Health Minister Zahid Maleque inaugurated the app, launched under an initiative of the Directorate General of Health Services (DGHS), at an event at Dhaka Medical College and Hospital.
The minister in his speech at the event said the government has made progress in dengue treatment and all measures have been taken to deal with the outbreak.
Through the new app, doctors and health workers can do fluid management of dengue patients along with determining their age, height, gender, etc. The app will help to indicate when and how much fluid a dengue patient needs.
People will also know how many beds are available in any hospital for dengue patients. The app can be downloaded from Google Play Store, according to the DGHS officials.
Earlier, an app - 'Stop Dengue' - was launched in 2019, but it failed to get mass people's response.
The health minister further said the number of dengue patients will not decrease, if mosquitoes do not decrease. If dengue patients increase, casualties will also increase.
"The number of dengue patients is increasing, which is worrying. We brought Covid-19 under control, and hopefully we can bring dengue under control," he added.
Meanwhile, the DGHS registered 11 more deaths due to the mosquito-borne fever, including eight from Dhaka, in 24 hours till 8:00 am on Tuesday. With the new deaths, the total number of casualties reached 657, including 476 from Dhaka.
A total of 2,782 new cases of hospitalisation were also reported during the same period across the country, including 951 from Dhaka.
The total number of dengue cases rose to 135,916. Of the total cases, 62,440 were from Dhaka, according to the DGHS.
A total of 9,132 people were being treated in hospitals across the country. Of them, 4,049 were from Dhaka. Of the total admitted, 126,127 patients made recovery and returned home, including 57,915 from Dhaka.
Last year, 281 people died of dengue, the second highest in the country's history, it noted.
A BSS report adds, entomologists off late found the conventional insecticides appeared ineffective against the dengue vector Aedes mosquitoes, saying these visibly developed a natural resistance against two traditional toxicants used to kill the deadly insects or destroy their larva.
"Toxic substances (insecticides) have turned sub-insecticide, losing their efficacy against mosquitoes," National Institute of Prevalence and Social Medicine's (NIPSOM) Entomology Department Chief Professor Dr Md Golam Sharower said on Tuesday.
The entomologist attributed the phenomenon to anti-mosquito workers' inefficacy in applying two insecticides - Malathion and Temephos - to kill mosquitoes or destroy larva with their traditional fogger machines.
But, the workers assigned by two city corporations could not properly spray the insecticides in appropriate dose for lack of knowledge, which largely made the dengue-carrying mosquitoes resistant to these.
He also said the city corporations largely failed (in handling the dengue outbreak), but they alone cannot perform the job without community engagement and coordination among the relevant organisations.
Jahangirnagar University's Zoology Professor Dr Kabirul Bashar, an entomologist by background, said, "It is very important to understand reproductive nature and lifecycle of Aedes mosquitoes (in particular) to take effective measures to halt the dengue menace and save human lives".
He also expressed doubts over practice of traditional methods to destroy Aedes.
"Since Aedes mosquitoes are generally found in residential areas, it is actually a domestic species and its management system must be different from other mosquito species."
"We need to recruit health workers to oversee a specific number of houses in particular areas in Dhaka throughout the year."
Besides, year-long monitoring system must be introduced to destroy potential breeding sources of Aedes mosquito, he added.
Dhaka North City Corporation (DNCC) officials said they recently bought 100 fogging machines from Germany's PulseFog, while work was underway to provide continued training to the persons engaged to operate the fogging machines and spray insecticides in appropriate doses at precise locations.
