Hageman factor

Haemorrhagic fever (also spelled hemorrhagic fever) is a term used to describe a severe illness in humans and animals caused by several families of viruses. These illnesses are characterized by high fever and bleeding disorders, often leading to high mortality rates.

Causes

Haemorrhagic fevers are caused by several families of viruses, including Arenaviridae, Filoviridae, Bunyaviridae, and Flaviviridae. These viruses can be transmitted to humans through various vectors, including mosquitoes, ticks, and rodents. Some haemorrhagic fevers, such as Ebola and Marburg virus disease, can also be transmitted from person to person.

Symptoms

The symptoms of haemorrhagic fever can vary depending on the specific virus involved. However, common symptoms include high fever, fatigue, dizziness, muscle aches, loss of strength, and exhaustion. As the disease progresses, patients may develop a high fever, shock, and bleeding into the skin and organs.

Treatment

Treatment for haemorrhagic fever is primarily supportive, as there are no specific antiviral treatments for many of these diseases. This can include rehydration, pain management, and treatment of any secondary infections. In some cases, antiviral drugs may be used.

Prevention

Prevention of haemorrhagic fever primarily involves avoiding contact with the vectors that transmit these diseases. This can include using insect repellent, wearing protective clothing, and avoiding areas known to be infested with the vectors.
