HOW LASSA FEVER IS TRANSMITTED

HOW LASSA FEVER IS TRANSMITTED

Humans usually become infected with lassa virus from exposure to urine or faeces
of infected mastomy rat. Lassa virus may also be spread between through direct contact with the blood, urine, faeces or other bodily secretions of a person infected with lassa fever. There is no epidemiological evidence supporting airborne spread between humans.
    Persons at greater risk are those living in rural areas where mastomys are usually found especially in communities where there is overcrowded living conditions, poor sanitation and poor reporting of persons showing symptoms of this disease. Health workers are at risk if they care for lassa fever patient in the absence of proper barrier nursing and infection control practices.

Diagnosis

Lassa fever is difficult to distinguish from other viral haemorrhagic fevers such as ebola virus and many other diseases that cause fever including malaria, shigellois, typiod fever and yellow fever. Definitive diagnosis requires testing that is available only in specialized laboratories located at irua, edo state and rivers state in the south south as well as other states in Nigeria.
