The virus was discovered first by the epidemiologist Jordi Casals-Ariet. He got infected and barely survived the illness back in 1969. This doctor has detected the virus in the blood of several nurses, who came back from West Africa.

He and his team studied the virus and few of the workers at the lab got infected. One of them even died, but Jordi Casals-Ariet survived. Further examinations of the Lassa fever were carried out in top security lab at CDC (Centers for Disease Control and Prevention) in Atlanta, USA.

  • Minor fever
  • Headache

lassa virus symptomsOver 80 percent of all the infected persons experience these mild disease manifestations. Due to the fact that people do not seek medical help it becomes hard to evaluate the size of the epidemic. Scientists believe that 100 to 300 thousand cases of Lassa Fever have taken place in the West Africa. However, no one knows for sure.

Severe Lassa Fever symptoms:

  • Vomiting
  • Nose, gum, eyes hemorrhaging
  • Swelling of the face
  • High fever
  • Severe pain in chest or back
  • Tremors
  • Shock

Around 20 percent of all the patients experience all or some of these symptoms. The death rate is not high, although doctors consider that this fever has taken the lives of over 5 000 people in West Africa. Plus, the fever can produce various complications, such as deafness.

Lassa fever treatment

lassa virus treatmentThe problem with Lassa fever is that it can rarely be timely diagnosed. Once that is done patients can be administered early treatment. Such antiviral drugs as Ribavirin produce positive effects in treating Lassa virus when given during the first week or so after getting infected. Later on patients should be treated accordingly to the symptoms they develop. Unfortunately there is no vaccine suitable to prevent Lassa virus.

Is there a new Lassa fever outbreak in Nigeria in 2016?

In the very beginning of the year Prof. Isaac F. Adewole, who is the minister of health has made a statement about this virus. He said that indeed Nigeria has been undergoing a new outbreak of the disease for over 6 weeks by now. And Port Harcourt is not the only place where the trouble is brewed. Presently over 8 states have been affected by the virus.

There are 14 confirmed cases of Lassa Fever with almost 80 suspected cases and 35 deaths possibly caused by the virus. This means Nigerians should be on guard and do everything possible to minimize their contact with rats and their extremists and seek medical help, if they suspect the chance of being infected with the virus.

I have realised, that there are much more diseases than we know or we are told. But i have read about this dangerous virus. It is rather scary, because each disease one day may become our problem. We, who live far from Africa, think that such viruses are far from us and have no any attitude to us. But we are wrong, because it is a worlds problem, and we all are the citizens of it! If we know much about viruses we have a possibility to avoid the infection, prevent the illness or to have a possible treat in time. It is useful information and I am glad, that I have a possibility to learn more about such kinds of viruses!
