Injecting female sex workers, men with sexual intercourse (MSM), and drug users is identified as a core population because of the highest risk of AIDS infection and infection.
Mami Shamiul Islam, director of Bangladesh's AIDS STD program, said the prevalence rate rose to 3.9% in 2016 from 0.7 in 2011.
Even in 2002, it was only 0.3 percent. Fell from 0.4% in 1998-99 when the first study ended.
He talked to reporters at the Bangladesh Health News Forum during a news conference.
The government runs programs through NGOs to prevent drug users from injecting needles into blood.
But this rise means that the program did not go well.
"I think it's a failure of the program for drug users," he said.
He added a new approach called Opioid Substitution Therapy or OST to deal with drug users sharing a syringe.
The OST is an "Advanced Harm Reduction Option" for drug users.
The government, through its supervised clinical environment, provides illegal drug users with prescription drugs, such as methadone, which are usually administered orally.
"Oral administration means there is no risk of HIV infection and we can gradually stop using the drugs. We have 1,700 drug users under the OST program so far," he said.
"The government is working to achieve its global goal in 2030, which means finding 90% of people infected with HIV, 90% of whom are treated and 90% are unable to spread HIV. "
Globally this is called 90-90-90.
The number of people infected with HIV has been 5,586 since the first case was discovered from 1989 to 2017.
924 of them died of AIDS.
However, as of 2017, about 13,000 people are HIV-infected, meaning that many people do not know their status.
December 1 World AIDS Day is the theme of 'Know Your Status' which emphasizes the need for voluntary testing for viral diseases.
Of the 865 cases of new HIV infections last year, 31% were return migrant workers.
