VIRAL INFECTIONS
Viral infections occur when viruses invade the body, infect cells, and multiply. They can affect different parts of the body and vary widely in severity, from the common cold to more severe illnesses like hepatitis or HIV.
Causes
Viral infections are caused by various viruses, which are microscopic pathogens that can infect cells. Common modes of transmission include:
- Airborne droplets: (e.g., flu, common cold).
- Direct contact: Skin-to-skin or mucous membrane contact (e.g., herpes).
- Contaminated food/water: (e.g., norovirus, rotavirus).
- Vector-borne: Via insects like mosquitoes (e.g., dengue, Zika).
- Blood and bodily fluids: (e.g., HIV, hepatitis B and C).
Common Types of Viral Infections
- Respiratory Viruses:
- Influenza, common cold (rhinovirus), COVID-19.
- Gastrointestinal Viruses:
- Norovirus, rotavirus.
- Skin Infections:
- Herpes simplex virus, varicella-zoster (chickenpox, shingles).
- Systemic Viruses:
- Dengue, chikungunya, HIV, hepatitis.
- Neurological Viruses:
- Rabies, poliovirus, Japanese encephalitis.
Symptoms
Symptoms vary depending on the virus and area of infection but may include:
- Fever.
- Fatigue and body aches.
- Cough and sore throat.
- Runny or stuffy nose.
- Headache.
- Skin rash or blisters.
- Nausea, vomiting, or diarrhea.
- Joint pain or muscle aches.
Diagnosis
- Clinical Evaluation:
- Based on symptoms and medical history.
- Lab Tests (if needed):
- Blood tests to identify viral markers or antibodies.
- PCR tests to detect viral genetic material.
- Rapid antigen tests for specific viruses (e.g., influenza, COVID-19).
Treatment
Viral infections generally do not respond to antibiotics.
Viral infections can be treated successfully with Homoeopathic medicines
- Supportive Care:
- Hydration, rest, and a nutritious diet.
