What Is COVID-19?
COVID-19 is an infectious disease caused by the novel coronavirus SARS-CoV-2, first identified in Wuhan, China in late 2019. Coronaviruses are a large family of viruses that can cause respiratory infections in both humans and animals. SARS-CoV-2 primarily affects the respiratory system and spreads mainly through droplets released when an infected person coughs, sneezes, or talks.
At MedicalPoint Hospital, we closely follow global guidelines in diagnosing and treating COVID-19, helping patients recover with expert care and advanced medical technology.
What Are the Initial Symptoms of COVID-19?
COVID-19 symptoms typically appear 2 to 14 days after exposure to the virus. While some individuals may remain asymptomatic, others may experience mild symptoms or progress to severe respiratory illness such as pneumonia.
Common symptoms include:
- Fever: Often above 38°C (100.4°F)
- Dry cough: Persistent and non-productive
- Shortness of breath: Especially in moderate to severe cases
- Fatigue: General feeling of tiredness and weakness
- Muscle or joint pain
- Sore throat
- Loss of smell or taste: May occur suddenly in some patients
- Headache
- Nasal congestion or runny nose
COVID-19 symptoms can vary depending on individual risk factors. Older adults and individuals with underlying conditions (diabetes, cardiovascular disease, obesity, etc.) are more prone to complications.
How Is COVID-19 Treated?
At MedicalPoint Hospital, we personalize COVID-19 treatment plans based on the severity of the infection, the patient’s medical history, and current health status. Treatment typically falls into three categories:
1. Mild Cases
- Rest and isolation
- Hydration: Encouraging fluid intake to prevent dehydration
- Fever and pain relief: Paracetamol is often used for symptom relief
2. Moderate Cases
- Antiviral drugs: Such as remdesivir may be prescribed to reduce viral replication
- Corticosteroids: Like dexamethasone to reduce inflammation
- Oxygen therapy: For patients with breathing difficulties
3. Severe Cases
- ICU admission: For patients with respiratory failure
- Mechanical ventilation: For those requiring assisted breathing
- ECMO (Extracorporeal Membrane Oxygenation): Advanced life support for severe respiratory failure
Additional or Investigational Therapies
- Monoclonal antibodies: Target the virus to prevent it from entering human cells
- Stem cell therapies (in research phase): May support immune recovery
Our multidisciplinary team—including infectious disease specialists, pulmonologists, and critical care doctors—works together to ensure the best possible outcome for every patient.
How Does the Immune System Fight COVID-19?
The immune system responds to SARS-CoV-2 infection with a two-phase defense:
1. Innate (Natural) Immunity
- Phagocytic cells (macrophages and neutrophils) quickly detect and destroy the virus
- Interferons and antiviral proteins block virus replication
2. Adaptive (Acquired) Immunity
- T cells (CD8+ cytotoxic cells) destroy virus-infected cells
- B cells produce antibodies that neutralize the virus and offer future protection
Vaccination plays a critical role in enhancing this immune response. It primes the immune system to recognize the virus quickly, reducing the risk of severe illness.
How Is COVID-19 Diagnosed?
At MedicalPoint Hospital, we use the latest diagnostic tools to ensure fast, accurate detection:
1. PCR Test (Polymerase Chain Reaction)
- Gold standard for detecting viral RNA
- Nasal or throat swab required
- Confirms active infection
2. Antigen Test
- Detects viral surface proteins
- Produces quicker results but may be less sensitive
- Useful in early detection in high-risk environments
3. Antibody Test
- Identifies past exposure by detecting immune response
- Not suitable for diagnosing active infection
4. Imaging (X-Ray / CT Scan)
- Used to assess lung involvement in moderate to severe cases
- Helps evaluate pneumonia, inflammation, or complications
All diagnostic decisions at MedicalPoint are made in accordance with current guidelines from the World Health Organization (WHO) and Turkish Ministry of Health, ensuring the highest standards of care.
When to Seek Medical Attention
You should seek immediate medical attention if you experience:
- Difficulty breathing
- Persistent chest pain or pressure
- Confusion or inability to stay awake
- Bluish lips or face
Prompt intervention improves outcomes. MedicalPoint Hospital offers 24/7 emergency services and isolation units for suspected or confirmed COVID-19 cases.
