Transmission of Bunyaviruses

Bunyaviruses are primarily transmitted through the bite of an infected mosquito or tick. They can also be transmitted through:

  • Contact with infected animals or their tissues
  • Contact with contaminated water or soil
  • Aerosol transmission in laboratory settings
  • Person-to-person contact, although this is rare

Diagnosis and Treatment of Bunyavirus Infections

Diagnosis of bunyavirus infections is typically made through a combination of clinical evaluation, laboratory tests, and epidemiological investigation. Treatment for bunyavirus infections is primarily supportive and may include:

  • Fluid replacement and management of electrolyte imbalances
  • Oxygen therapy and respiratory support
  • Pain management and anti-inflammatory medications
  • Antiviral medications, although their effectiveness can vary depending on the specific virus and disease
