- Remember that Lassa fever is a contagious viral infection, though, and that it could spread beyond its current footprint at any time. So don’t panic, but practice reasonable caution.
- If you are in the endemic zone, pay attention to any warnings posted by governmental or health organizations, steer clear of unsanitary conditions and infected persons, and utilize the other precautions discussed in more detail in this article.
- If a person who has recently been in the endemic region presents with flu-like symptoms or signs of a gastrointestinal illness, it would be prudent to avoid contact and have that person seek a medical evaluation.
- The virus is usually transmitted through contamination of food or surfaces by rat urine or droppings. Eating the rodent, which is not unheard of, may also transmit the virus.
- Steering clear of rats and rat excrement is good practice at all times, but you should take particular care within the endemic region. Avoid areas where there is accessible food or trash, because there is a good chance the rats are there, even if you don’t see them.
Taking Precautions
- Keeping your own area clean will do little good if your neighbor’s place is a rodent hotel, however. Organizations that are battling Lassa fever regularly promote “community hygiene” programs in an effort to make entire areas less hospitable to rodents.
- In one of the rare cases of Lassa fever in the U.S., a traveler who returned from western Africa died in New Jersey in May 2015. As part of the precautions taken, anyone who had been in close proximity to the victim was monitored for 21 days.
- The person who died of Lassa fever in New Jersey in 2015 failed to respond accurately about recently traveling to the endemic zone, and as a result was sent home from the hospital initially. This probably contributed the patient’s death and put others at unnecessary risk. Never withhold information that may indicate you have Lassa fever; you are not doing yourself or others any favors.
Understanding the Illness
- While often compared to the Ebola virus because of overlaps in outbreak zones, Lassa fever is less readily communicable and has a far smaller fatality rate (about one percent of infected persons, compared to 70% for Ebola). That still counts for some five thousand deaths per year, and Lassa fever should by no means be underestimated.
- The incubation period is typically six to 21 days, and the illness usually lasts for one to four weeks. In fatal cases, the cause of death is usually multi-organ failure.
- Deafness occurs in about 25% of all cases, regardless of severity otherwise. Of these instances, the hearing loss reverses itself about half of the time, usually in one to three months.
- Isolation of infected patients during treatment is always advised. Barrier protections and other infection-control procedures are necessary.
