Female sex workers, men with sex with men (MSM), and spray drug users are identified as the key populations because they have the highest risk of contracting and transmitting HIV.
Professor Md Shamiul Islam, AIDS Line Director, the STD Program in Bangladesh said that the frequency rose to 3.9 per cent in 2016 from 0.7 in 2011.
It was only 0.3 percent even in 2002, a 0.4 per cent decrease in 1998-99 when the first study was carried out.
"The increase is the result of the injecting of drug users," he said as she interacted with journalists of the Bangladesh Health Journalists Forum on Sunday at her office.
The government runs programs through NGOs to prevent the injecting of drug users from the needle sharing of the virus entering the blood.
But this progress means that the program has not gone well.
"I can call it the failure of the program that had been targeted at drug users injecting," he said.
He added that they had introduced a new approach of the name Opioid Substitution Therapy or OST to deal with drug users who spray a spray.
OST is a "higher harm reduction option" for the drug users.
The government through its supervised clinical settings supplying drug users with a new drug, prescribed medication such as methane, usually administered orally.
"Verbal administration means that there is no risk of HIV infection and also gradually we can take it out of the use of drugs. We have 1,700 drug users to date under this OST program," said line director.
"The government is working to reach the global goal of 2030 which means that 90 per cent of people living with HIV can find that 90 per cent of them will be treatment and 90 per cent of them will be a stage of where they can not transfer the virus. "
Globally, this is called 90-90-90, he says.
The number of people living with HIV as confirmed by the government through laboratory tests is 5,586 since the first case was found between 1989 and 2017.
Of these, 924 have died of AIDS.
But there is an estimate of the number of people living with HIV about 13,000 of 2017, which means that a large number of people do not know their status.
