There are several types of viral hemorrhagic fevers, which are considered infectious diseases and may be life-threatening. These viruses can cause damage to different parts of the body, including damage to the walls of small blood vessels. This can lead to bleeding and prevent normal blood clotting. These viruses may infect insects or rodents, and humans can become infected through contact with the body or bodily fluids of infected individuals, exposure to infected rodent waste, or through the bites of insects such as mosquitoes or ticks. These viruses may also spread from one person to another. Symptoms of Hemorrhagic Fever Symptoms may vary slightly from one person to another and can affect different organs of the body. They may also differ depending on the specific disease. The main symptoms of viral hemorrhagic fever may include the following: Early Symptoms • High body temperature (fever). • Fatigue, tiredness, or weakness. • Muscle, bone, or joint pain. • Nausea and vomiting. • Diarrhea. Life-Threatening Symptoms That May Lead to Death • Bleeding under the skin, inside the body, or from the mouth, eyes, or ears. • Nervous system problems. • Fainting or coma. • Lack of concentration and awareness of the surrounding environment, a condition known as delirium. • Kidney failure. • Difficulty breathing and respiratory failure. • Liver impairment or liver failure. People with severe cases often show signs of bleeding, which may occur under the skin, in internal organs, or from body openings such as the mouth, eyes, or ears. Blood loss is often a cause of death. Complications Viral hemorrhagic fevers may cause the following complications: • Septic shock. • Multiple organ failure. • Death. Prevention and Risk Factors for Infection The following activities and exposures may increase the risk of contracting the disease: • Working with infected individuals. • Slaughtering or eating infected animals. • Having unprotected sexual intercourse with an infected person. • Working in buildings infested with rats. • Coming into contact with an infected person's blood or other bodily fluids.
