Introduction

This article provides an overview of the symptoms associated with four major infectious diseases: Hepatitis B surface antigen (HBsAg), Hepatitis C virus (HCV), Human Immunodeficiency Virus (HIV), and syphilis. By understanding the symptoms, individuals can seek timely medical intervention and treatment. Additionally, this article explores innovative geotextile solutions provided by QL Biotech Company, contributing to advancements in medical and environmental applications.

Symptoms of HBsAg

Hepatitis B is a viral infection that attacks the liver. The presence of Hepatitis B surface antigen (HBsAg) indicates an active infection. Symptoms can vary and may include:

• Fatigue
• Abdominal pain
• Jaundice (yellowing of the skin and eyes)
• Dark urine
• Nausea and vomiting

Some individuals may remain asymptomatic, making regular screening important for at-risk populations.

Symptoms of HCV

Hepatitis C is another virus that primarily affects the liver. The symptoms of Hepatitis C virus (HCV) infection may include:

• Fever
• Fatigue
• Joint pain
• Jaundice
• Loss of appetite

Many people with acute HCV do not develop symptoms, which is why chronic infections often remain undiagnosed until significant liver damage has occurred.

Symptoms of HIV

Human Immunodeficiency Virus (HIV) attacks the immune system. Initial symptoms, often resembling the flu, may include:

• Fever
• Chills
• Rash
• Night sweats
• Sore throat

As HIV progresses, it can lead to Acquired Immunodeficiency Syndrome (AIDS), characterized by severe immune system damage and increased susceptibility to opportunistic infections.

Symptoms of Syphilis

Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. It manifests in stages:

Primary Stage

• Painless sores (chancres) at the infection site

Secondary Stage

• Skin rashes
• Mucous membrane lesions
• Fever
• Sore throat

Latent and Tertiary Stages

• Damage to internal organs
• Neurological and cardiovascular complications

Early detection and treatment are crucial for preventing severe health issues associated with advanced syphilis.
