Lassa Fever

Lassa fever is a severe viral disease that occurs exclusively in Central and Western Africa. This disease is caused by the Lassa virus, which is transmitted to humans through contact with the secretions of infected rodents, especially rats. Most cases of Lassa fever occur in areas where rats are common.

After an incubation period that lasts from 3 to 21 days, the person develops severe headache and muscle pain, and the temperature rises sharply. Difficulty swallowing, as well as coughing and nausea are common. In some cases, conjunctivitis may develop, that is, inflammation of the eye mucous membranes. Some patients may have a fever that lasts for a few days and then decreases for a few days before rising back to a high level.

In approximately 50% of cases, patients die from heart or kidney failure. While most patients recover, some may experience complications such as deafness, dizziness, weakness and various vision problems.

The most effective treatment for Lassa fever is plasma replacement, which can help improve the patient's condition and reduce the likelihood of death. There are also drugs that are sensitive to Lassa virus, including ribavirin.

However, because Lassa fever can mimic other diseases such as malaria, diphtheria or influenza, diagnosing the disease can be difficult. Therefore, it is important to consult a doctor at the first suspicion of Lassa fever, especially if you live in an area where the disease is common.

Overall, Lassa fever is a serious illness that can lead to death. However, early seeking medical help and proper treatment can help reduce the risks of complications and increase the likelihood of recovery.

Lassa fever is a severe viral disease that occurs exclusively in central and western Africa and has a high mortality rate. The disease develops after an incubation period of 3 to 21 days and is accompanied by severe headache and muscle pain, high fever, and difficulty swallowing. On average, about 50% of those affected die from heart or kidney failure, making this disease one of the most dangerous in the world.

The main treatment for Lassa fever is plasma replacement - transfusion of blood plasma obtained from a healthy donor into the patient. This allows you to reduce the level of the virus in the body and reduce the symptoms of the disease. However, the virus that causes this disease is only sensitive to ribavirin, which is used as an adjunctive treatment.

Lassa fever poses a serious threat to the health and lives of people in African countries where it is common. This disease requires rapid and effective treatment to prevent its spread and reduce mortality in the population.
