According to medical experts, Lassa fever is transmitted when the saliva, urine, and excreta of multi-mammalian rats come into contact with humans. Human-to-human transmission is rare but can occur through contact with the body fluids of an infected person. In some cases, Lassa fever has similar symptoms to malaria, appearing between one and three weeks after exposure to the virus. In mild cases, the disease causes fever, fatigue, weakness, and headache.
Secondary transmission from person to person can also occur following exposure to the virus in the blood, tissue, urine, feces, or other bodily secretions of an infected patient.
The NCDC further noted that the predominant age group so far affected by the disease in Nigeria ranged between 21 and 30 years, the disease control agency stated.
The Agency explained that the animal vector for the Lassa virus, the multimammate rat, is found throughout the west African region, thereby calling on neighboring countries to stay alert on the spread of the Lassa fever.
Meanwhile, NCDC is distributing medical response supplies to states and treatment centers, as part of measures to control the spread of the disease.
