Fever and COVID-19

Fever and COVID-19

Fever is one of the most common presenting symptoms of a SARS-COV-2 infection.

In an observational study presented in the Clinical Infectious Disease Journal in March 2020, researches found that only 74.1% of severe cases of SARS-COV-2 presented with fever and in those that did have fever, it was significantly lower than in general patients. These findings suggest that patients with a weak fever response to the virus are more vulnerable to serious disease.

Fever: body temperature >100.4 F

Ideal microbe killing temperature: 102-103 F

Concerns with fever:
• Dehydration: >104 F
• Dangerous: > 107 F
• Febrile seizure:
• Most common ages 6mo-5y
• Often runs in families
• Triggered by fever >101 F
• Most brief (<15 minutes) seizures do not cause long term health consequences

Common fever drugs:
• Acetaminophen (Tylenol): 10–15 mg/kg/dose every 4–6 hours
• Ibuprofen (Advil): 5–10 mg/kg/dose every 8 hours

Cautions with Ibuprofen in SARS-COV-2 infection:
• May suppress antibody formation
• May increase ACE2, leading to increased viral entry into cells

Cautions with Acetaminophen (Tylenol):
• May suppress the liver’s production of glutathione, an important antioxidant
• Take 600mg NAC for adults or 200mg for children 3 times per day for 3 days after taking acetaminophen

Naturopathic treatment of fever:

First do no harm: If possible, avoid suppressing a fever <102-103F

Hydrotherapy:
• To lower the body temperature if fever is uncomfortable: Tepid (81–92F) or Neutral (93–96F) sponge baths (gentle friction promotes peripheral circulation and improves heat loss)
• Under a doctors supervision only, consider raising a weak (less than 102) fever using hyperthermic therapies (see post on hydrotherapy)

Botanical medicine:
• Diaphoretics (sweat inducers): yarrow (Achillea millefolium), linden (Tilia tomentosa), meadowsweet (Filipendula ulmaria).

Nutrition:
• Starve a fever: drink clear broth, electrolyte drinks or ice chips
