These new cases bring the number of swine flu infection in Bangladesh to 194 since June 18.
"The situation is still at level 2, but as the infection is spreading rapidly, we're taking preparations to manage the patients presuming a level 3 ahead," said Senior Scientific Officer of the Institute of Epidemiology, Disease Control and Research (IEDCR) Moshtaque Hossain.
He was speaking at a seminar on swine flu at the Bangabandhu Sheikh Mujib Medical University (BSMMU).
The experts said there is no alternative to quarantining the affected at home with regular treatment and infection control is an important priority. But the people with Severe Acute Respiratory Illness (SARI), diabetes and hypertension should be treated with antiviral drugs immediately.
