Reference only, to read alongside your own examination.

Symptoms — what the patient reports (7)

  • Symptoms usually begin 7 to 39 days after exposure, starting with headache, muscle aches, vomiting, and abdominal pain [abdominal pain · headache · muscle pain · vomiting]
  • Roughly three to six days into the illness, breathlessness, fluid in the lungs, low blood pressure, and shock can develop quickly [breathlessness · hypotension · shock]
  • A history of contact with rodents, their droppings, or a rodent bite - especially in farming or forestry work - is a key exposure clue [animal bite]
  • There are two syndromes. Haemorrhagic fever renal syndrome brings acute kidney injury, thrombocytopenia, fever and low blood pressure [fever · hypotension]
  • The pulmonary syndrome instead brings fever, muscle aches and severe respiratory compromise, and belongs to North and South America [fever · muscle pain]
  • Red flag: the pulmonary syndrome often needs mechanical ventilation and kills up to 40%, against 1% to 15% for the renal one
  • It is caught by breathing in aerosolised urine or droppings, or from an animal bite, and the rodents carrying it are themselves perfectly well [animal bite]

Signs — what you find (3)

  • Reduced urine output, petechiae, and bleeding may be observed [bleeding · petechiae]
  • Severe infection can cause metabolic acidosis
  • Cardiovascular collapse is a possible complication during the respiratory phase [collapse]

Tests (6)

  • An initial chest x-ray shows pulmonary edema in only about a third of patients, but nearly all show interstitial edema by 48 hours after admission
  • Roughly two-thirds of patients develop lower-lobe or central lung opacities with some degree of pleural fluid
  • Thrombocytopenia appears on blood counts once hospitalisation is required and helps predict how the disease will progress
  • A blood smear can show immature white cells along with severe thrombocytopenia, low sodium, and blood in the urine
  • Diagnosis relies on immunofluorescence, immunoblot testing, or an IgM ELISA, which is the preferred method
  • There is no cure, and the treatment is supportive

If not this — what else fits (4)

  • ARDS shares acute breathlessness with bilateral non-cardiogenic infiltrates and a PaO2/FiO2 ratio under 300, and is hard to distinguish from hantavirus
  • Broad-spectrum antibiotics for suspected mycobacterial pneumonia have not been shown to change outcomes in hantavirus infection
  • An influenza PCR test can help rule in influenza pneumonia rather than hantavirus
  • Viral haemorrhagic fevers need specific PCR testing to pin down a single causative organism

NO DRUG THERAPY IN PRIMARY CARE (RECOGNITION & REFERRAL)

1st line
Adult dose and duration

Rodent-borne viral illness causing fever with renal or pulmonary syndromes. Not an established clinical entity in Egypt, so this is a recognise-and-refer diagnosis if ever suspected in someone with relevant travel or rodent exposure abroad. - Refer

Paediatric dose

Children follow the same pathway: recognise and refer. No primary-care medicine is implied.

Dose source

No dose - referral pathway, no medicine given in primary care

Why

Rodent-borne viral illness causing fever with renal or pulmonary syndromes. Not an established clinical entity in Egypt, so this is a recognise-and-refer diagnosis if ever suspected in someone with relevant travel or rodent exposure abroad.

Cautions
  • Not endemic in Egypt. Relevant to a returning traveller or an imported case; consider the travel history before anything else.
  • No medicine is prescribed for this in primary care - this entry is for recognition and referral. Anything given is decided by the service it is referred to.
  • RED FLAG - Rapid respiratory compromise (dyspnea, pulmonary edema, hypotension, shock) develops 3 to 6 days after the initial prodrome.
  • RED FLAG - Thrombocytopenia or a decreasing platelet count warrants immediate hospital admission.
  • RED FLAG - Respiratory distress suggesting hantavirus pulmonary syndrome, oliguria or acute renal failure, or rodent exposure in a region where hantavirus is known to circulate.
