The Nigeria Centre for Disease Control (NCDC) has said that Ondo, Edo and Bauchi states account for 10 new additional Lassa fever cases reported in the country.
The NCDC via its official website said that Ondo accounts for (30 per cent), Edo (26 per cent) and Bauchi (14 per cent) recorded the cases between July 25 to July 31, 2022.
The health agency said that the three states account for 70 per cent of the burden of infections in the country.
The agency said that this brings the total number of confirmed cases in 2022 to 867, with 164 deaths.
The NCDC said that in 2022 about 24 states of the federation have reported at least one confirmed case across 99 local government areas.
According to it, in week 30 (July 25 to 31), the number of new confirmed cases is the same as reported in week 29, 2022, with 10 cases. These were reported in Ondo, Edo and Bauchi states.
“Cumulatively from week 1 to week 30, 2022, 164 deaths have been reported with a case fatality rate (CFR) of 18.9 per cent which is lower than the CFR for the same period in 2021 (22.8 per cent).
“The predominant age group affected is 21-30 years (range 0 to 90 years, median age 30 years). The male-to-female ratio for confirmed cases is 1:0.8.
“The number of suspected cases has increased compared to that reported for the same period in 2021.
“No new healthcare worker affected in the reporting week 30.
“National Lassa fever multi-partner, multi-sectoral technical working group (TWG) continues to coordinate the response activities at all levels.”
The Nigerian Public Health Institute said that primary transmission of the Lassa virus from its host to humans can be prevented by avoiding contact with mastomys rodents, especially in the geographic regions where outbreaks occur.
“Putting food away in rodent-proof containers and keeping the home clean help to discourage rodents from entering homes.
“Using these rodents as a food source is not recommended. Trapping in and around homes can help reduce rodent populations; however, the wide distribution of mastomys in Africa makes complete control of this rodent reservoir impractical,” it said.
It also advised that when caring for patients with Lassa fever, further transmission of the disease through person-to-person contact or nosocomial routes can be avoided by taking preventive precautions against contact with patient secretions.
“Such precautions include wearing protective clothing, such as masks, gloves, gowns, and goggles; using infection control measures, such as complete equipment sterilization; and isolating infected patients from contact with unprotected persons until the disease has run its course,” it advised.
