I got this publication in the office memo and it is worth sharing to save lives.
- Lassa fever is an acute viral infection caused by the Lassa virus.
- Everyone must take special care as Lassa fever is common to West Africa and it is an endemic disease in Nigeria.
- The United States Centers for Control and Prevention states that the viral disease was first discovered in 1969 when two missionary nurses died in a village in Nigeria.
- The agency states that the virus is named after the town in Nigeria where the first cases occurred.
- There is a recent outbreak in Nigeria over the past 7weeks, which has claimed 40 lives.
- 17 of the 36 states in Nigeria have been affected by this and a total of 397 cases have been reported, out of which 87 have been confirmed.
- The reservoir, or host, of Lassa virus is a rodent known as the multimammate rat of the genus Mastomys. It is not certain which species of Mastomys are associated with Lassa; however, at least two species carry the virus in some countries.
- It is also spread by direct contact with the blood, urine, faeces or other bodily secretions of a person with Lassa fever. In short, those who contract this virus must have touched or eaten something that had been touched by an infected rat
- Humans usually become infected with Lassa virus from exposure to urine or faeces of infected Mastomys rats. 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.
- There is no scientific evidence supporting airborne spread between humans.
- Person-to-person transmission occurs in both community and health-care settings, where the virus may be spread by contaminated medical equipment, such as re-used needles.
- Sexual transmission of Lassa virus has been reported.
- 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.
- As in Ebola, the symptoms of Lassa fever occur one to three weeks after the patient comes into contact with the virus. Its general symptoms may include general malaise, weakness, and headache in mild cases but quickly adds that when untreated, the infection may progress to respiratory distress, bleeding in the gums, repeated vomiting, facial swelling, pain in the chest, back and abdomen as well as shock.
- Neurological problems such as hearing loss, tremours, and encephalitis are symptoms of severe cases and if left untreated, death may occur within two weeks after symptom onset due to multi-organ failure in an infected person.
- The most common complication of Lassa fever is deafness. Various degrees of deafness occur in approximately one-third of infections, and in many cases hearing loss is permanent. As far as is known, severity of the disease does not affect this complication: deafness may develop in mild as well as in severe cases.
- Death usually occurs within 14 days of onset in severe cases. The disease is worse in pregnant women and nursing mothers.
- Preventing Lassa fever is first about knowing the source. The disease is spread by exposure to and eating of food contaminated with rat dropping or urine.
- Store food, cooking utensils and drinking water properly in rodent-proof containers.
- Keep homes clean and discourage rodent entry. Block all rat hideouts.
- Using rodent as food source is discouraged.
- Clean traps and dispose carcass neatly.
- “Soaking of Garri” as a meal should be discouraged for now.
- “Tasting of raw food” in the markets before purchases should be discouraged for now.
- Cook all foods thoroughly
- If you suspect that rat has eaten any food, discard it
- Hand washing with soap and running water regularly.
- Early treatment and proper fever management can improve survival chances. Report all suspected cases to appropriate Health Authorities.
I think the information above should help.
Do the needful.
