Introduction:

COVID-19, caused by SARS-CoV-2, emerged as a global health crisis in late 2019. Despite tremendous advances in understanding its structure, transmission, and epidemiological impact, critical questions remain about its origins, mutations, and long-term implications. This comprehensive review by Raza et al. unpacks the genetic evolution, spread, and systemic impacts of the virus.

Unraveling the Genomic Structure of SARS CoV-2

  • SARS-CoV-2 belongs to the β-coronavirus genus and shares 96.2% genome identity with bat coronavirus RaTG13.
  • It utilizes the ACE2 receptorfound in human lungs and heartsto invade host cells.
  • Genetic analysis confirms its close phylogenetic relation to SARS-CoV and MERS-CoV, though with greater transmissibility.

Global Epidemiological Footprint

  • First detected in Wuhan, China, in December 2019.
  • As of April 2020, over 2 million confirmed cases and 129,000+ deaths globally.
  • The virus’s R₀ (basic reproduction number) is estimated around 2.2, indicating rapid spread

Clinical Manifestations and At-Risk Populatio

  • Mild cases: fever, cough, sore throat, and fatigue.
  • Severe cases: acute respiratory distress syndrome (ARDS), septic shock, and multi-organ failure.
  • Individuals with comorbidities such as diabetes, cardiovascular diseases, and respiratory illnesses are at greater risk.

Cardiovascular Impact and Myocardial Injury

  • Patients with existing heart conditions are at higher risk of mortality.
  • Elevated levels of troponin I and troponin T are strong indicators of myocardial damage in COVID-19 patients.
  • A study in Wuhan found a 51.2% mortality rate among patients with cardiac injury, compared to 4.5% in those without.

The American College of Cardiology (ACC) highlights the need for careful cardiovascular monitoring in COVID-19 patients, especially those with elevated biomarkers.

ACE2 Receptor: The Gateway to Infectio

  • ACE2 is widely expressed in lungs and heart tissues.
  • Medications like ACE inhibitors may alter ACE2 expression posing challenges in treating hypertensive patients.
  • This dual role complicates treatment in individuals with preexisting cardiovascular conditions.

Pregnancy and Vertical Transmission

  • Current data indicates no vertical transmission of SARS-CoV-2 from mother to infant.
  • Among 38 COVID-19-positive pregnant women, no maternal deaths or infected neonates were reported.
  • Studies suggest pregnancy complications may arise due to the physiological strain but not directly from viral transmission.

The Role of Pets in Transmission

  • Cases of pet dogs and zoo animals testing positive were reported, yet no evidence confirms pet-to-human transmission.
  • WHO and CDC recommend precautionary separation from animals during human infection periods.

Unusual Ally Copper as a Preventive Tool

  • Copper surfaces deactivate SARS-CoV-2 rapidlyacting as an effective antimicrobial.
  • Hospitals using copper surfaces reported fewer infection rates.
  • Experts recommend integrating copper in high-touch public surfaces to curb viral transmission.
