Bello gave the directive in a statement signed by his Chief Press Secretary, Mr Hamzat Sule, on Wednesday in Abuja.
The statement said that the directive was a follow up to earlier tips on how to prevent the spread of the disease.
It recalled that the lone case in the territory was that of a man on transit.
“But the FCT Administration will not leave anything to chance on the lives and well-being of all the residents and visitors, as this is paramount to this administration.’’
The minister, therefore, directed the FCT Disease Control and Disease Surveillance Department to endeavour to be on top of any eventuality that might arise.
The statement said that he also instructed the Notification Officers in all the six area councils to be on high alert by stepping up disease surveillance activities within their various localities, especially at the border communities.
He emphasised that all the nooks and crannies of the 8,000 sq. kms. of the territory must be well policed, to deal with any case at a very short notice.
“The Heads of Health Departments in the area councils are equally directed to further step up sensitisation activities in the communities – markets, motor parks, churches and mosques,” the statement added.
Bello further urged the health workers to be proactive in their approach in order to avoid the unfortunate incident that led to the death of the transit victim.
The statement said that the minister also advised residents of the territory to imbibe the habit of a clean environment, to ward off all rodents from their houses.
“Hygienic practices will go a long way in curbing not only Lassa Fever but also other diseases associated with dirty environment,” the statement said.
