Name of the Condition

• COVID-19
• Technical term: Coronavirus Disease 2019

Summary

COVID-19 is a respiratory illness caused by the SARS-CoV-2 virus. It emerged in late 2019 and quickly became a global pandemic, affecting millions of people worldwide. The condition can range from mild symptoms to severe illness and death.

Causes

COVID-19 is caused by infection with the novel coronavirus SARS-CoV-2. It primarily spreads through respiratory droplets when an infected person coughs, sneezes, or talks. Transmission can also occur via contact with contaminated surfaces followed by touching the face.

Risk Factors

• Older age (65 and above)
• Pre-existing health conditions such as heart disease, diabetes, or respiratory illnesses
• Compromised immune system
• Living or working in crowded or high-transmission areas
• Lack of vaccination or booster doses

Symptoms

• Fever or chills
• Cough
• Shortness of breath or difficulty breathing
• Fatigue
• Muscle or body aches
• New loss of taste or smell
• Sore throat
• Congestion or runny nose
• Nausea or vomiting
• Diarrhea

Diagnosis

• Polymerase Chain Reaction (PCR) test for viral RNA
• Rapid Antigen Tests
• Serological tests to detect antibodies
• Chest imaging for severe cases

Treatment Options

• Supportive care including rest, hydration, and antipyretics
• Antiviral medications (e.g., remdesivir)
• Monoclonal antibodies for high-risk patients
• Hospitalization and intensive care for severe cases
• Supplemental oxygen or mechanical ventilation if necessary

Prognosis and Follow-Up

• Many recover with mild symptoms, but recovery can take weeks to months.
• Severe cases can result in long-term health issues or death.
• Regular follow-up care is essential for those with prolonged symptoms, often referred to as "Long COVID."

Complications

• Acute respiratory distress syndrome (ARDS)
• Heart and kidney damage
• Blood clots
• Chronic fatigue and "Long COVID" symptoms
