It is no longer news that Lassa fever in Nigeria is gradually spreading to all states of the country. A lot is in the air about how the disease is transmitted to humans. Humans usually become infected with Lassa virus from exposure to urine or faeces of infected Mastomys rats. This is especially so in houses where overcrowding is a big issue, like hostels, lodges, shanties etc.
But today, getting you to understand that rats is just one part of the transmission route is my aim.
Lassa virus may also be spread between humans through direct contact with the blood, urine, faeces, or other bodily secretions of a person infected with Lassa fever. That is why some studies have indicated that hospital Personnels, like doctors, nurses, are at a higher risk of getting the disease.
There is no evidence to show that Lassa Fever is airborne, although there have been reported cases of transmission through sex.
In Summary, Lassa fever occurs in all age groups and both sexes. Persons at greatest risk are those living in rural areas where Mastomys are usually found, especially in communities with poor sanitation or crowded living conditions. Health workers are at risk if caring for Lassa fever patients in the absence of proper barrier nursing and infection control practices.
