Introduction:
The global impact of COVID-19 continues to prompt critical research into how we can better understand and manage the virus. One intriguing approach focuses on the role of pH balance in viral viability and disease severity. A recent mini-review published in the International Journal of Clinical Virology delves into the relationship between blood alkalinity and SARS-CoV-2 stability, offering promising insights for therapeutic strategies.

Main Content Sections:
- SARS-CoV-2 is most stable in an acidic environment (pH 6.0–6.5).
- In contrast, human blood operates in an alkaline range of 7.35–7.45.
- This mismatch suggests that maintaining or slightly increasing alkalinity could weaken the virus.
Role of Hemoglobin in pH and Oxygenation
- Hemoglobin not only transports oxygen but also acts as a buffer to maintain blood pH.
- A drop in pH weakens hemoglobin’s ability to bind oxygen a condition exacerbated during infection.
- This leads to hypoxia, a major complication in severe COVID-19 cases.
The Werigo-Bohr Effect
- Explains how low pH interferes with oxygen binding, highlighting why patients experience oxygenation issues even without visible lung damage.
Coronavirus Strategy: pH Adaptation
- The virus may trigger local pH shifts to suit its acidic stability range, enhancing its survivability.
- Damaged alveoli from infection reduce CO₂ removal, further lowering blood pH and promoting viral propagation.
Blood Pressure, Acidosis, and COVID-19
- Acidosis correlates with elevated blood pressure and intracranial pressure, worsening patient outcomes.
- Some hypertension medications may aid by helping stabilize pH and vascular function.
Therapeutic Recommendations
- Short-term: Use of micro-alkaline additives in inhaled air under controlled conditions.
- Mid-term: Application of slaked lime in patient environments to reduce CO₂ and indirectly boost oxygenation.
- Long-term: Develop daily pH monitoring protocols as part of infectious disease management.
Integration of External Medical Source
The American Thoracic Society (ATS) has long emphasized the importance of gas exchange and buffering systems in respiratory care. The insights from this review align with the growing need for pH-focused management strategies in critical care settings.
