Haemorrhagic Viral Diseases

Haemorrhagic viral diseases are a group of infections caused by different viruses that affect multiple organ systems and cause bleeding disorders. These diseases can be severe and life-threatening, with no specific treatments for most of them. For instance:

  • Hantaviruses cause haemorrhagic fever with renal syndrome. It can lead to acute kidney injury, fever, and bleeding.
  • The Ebola virus can cause severe haemorrhagic fever with a high mortality rate. Symptoms include fever, headache, muscle pain, and internal and external bleeding.
  • Dengue fever is another common haemorrhagic virus that leads to further complications.
  • Lassa virus leads to haemorrhage, encephalitis, and multi-organ failure.
  • Crimean-Congo haemorrhagic fever is also a viral condition that can lead to bleeding, fever, and multiple organ failure.

Symptoms

Recent statics indicated that over 5 to 20 cases of Crimean-Congo haemorrhagic fever are reported annually in South Africa.

Some of the primary medical conditions or symptoms associated with haemorrhagic viral diseases include:

  • High Fever: Many haemorrhagic viral diseases cause a fever, which chills and sweating may accompany.
  • Body aches: Muscle and joint pain are common symptoms of viral diseases, including haemorrhagic diseases.
  • Bleeding: Bleeding is a common medical condition in many hemorrhagic viral diseases. It can occur from multiple sites, including the nose, mouth, ears, gums, and gastrointestinal tract. In severe cases, patients may experience internal bleeding.
  • Headache: Hemorrhagic viral diseases can cause severe headaches.
  • Fatigue: Fatigue and weakness increase as the viral attack worsens.
  • Skin rash: You can develop a skin rash, which may be accompanied by itching in Hemorrhagic viral diseases.

All patients with hemorrhagic viral diseases will experience all these symptoms but the severity of them can vary widely.

Causes

Hemorrhagic viral diseases are typically transmitted through contact with infected animals or other infected humans. For instance,

  • Contact with infected animals, such as fruit bats, or human bodily fluids, such as blood, sweat, and urine, can transmit the Ebola virus and Marburg virus.
  • You may develop Lassa fever if you come in contact with infected rodents or their urine and droppings. The virus can also be contracted from person to person through contact with bodily fluids.
  • A bite from an infected mosquito can cause the Dengue virus and yellow fever virus.
  • Tick bites, infected animal blood, and human bodily fluids can cause Crimean-Congo haemorrhagic fever.

Risk Factors

The risk factors for haemorrhagic viral diseases vary depending on the specific virus, the mode of transmission, and the individual’s immune response. However, you may be prone to haemorrhagic viral diseases due to the following factors.

Exposure to Infected Animals: Many haemorrhagic viral diseases are zoonotic, which means they are transmitted to humans from infected animals. People who work with animals, such as farmers and veterinarians, are at increased risk of exposure to these viruses.

Travel to Endemic Areas: Some haemorrhagic viral diseases are more common in certain regions, such as Africa and South America.

Poor Sanitation: Contaminated water or food, such as hepatitis E, can be more common in areas with poor sanitation and increase the risk of Haemorrhagic diseases.

Diagnosis or Complications

Diagnosing haemorrhagic viral diseases require lab tests, clinical assessments, and imaging studies. Your doctor can also take a PCR test (polymerase chain reaction) to detect viral DNA or RNA in blood or other bodily fluids, providing a more specific diagnosis than other tests.

Not treating a viral disease on time can cause bleeding from multiple sites, leading to anaemia, low blood pressure, and shock. You may also suffer from multiple organ failure.

Treatment & Prevention

There are currently no specific antiviral treatments for many haemorrhagic viral diseases, but supportive care can effectively manage symptoms and reduce complications. Some pain medications can be used to manage body aches, headaches, and other symptoms.

Prevention strategies for haemorrhagic viral diseases include avoiding contact with infected animals or their bodily fluids, practising good hygiene, using insect repellent to prevent mosquito bites, and getting vaccinated against some viruses, such as yellow fever.

If you suspect you may have been exposed to a haemorrhagic viral disease, seek medical attention promptly.
