[Symposium "infections, recently worth noticing". Introductory address]

Area of Science:

• Infectious Diseases
• Microbiology
• Public Health

Context:

• The development of antibiotics and vaccines has not eradicated bacterial and viral infections.
• Antibiotic-resistant bacteria and emerging viral strains pose significant global health challenges.
• Healthcare-associated infections, particularly from methicillin-resistant Staphylococcus aureus (MRSA), are a major concern in hospital management.

Purpose:

• To present recent research on critical infectious microorganisms: HIV, MRSA, and HCV.
• To enhance understanding of the challenges posed by antibiotic resistance and viral mutations.
• To inform healthcare professionals about the risks associated with hazardous microorganisms.

Summary:

• The emergence of antibiotic-resistant bacteria and variant viruses, such as HIV and Hepatitis C Virus (HCV), has proven initial eradication hopes illusory.
• HIV remains a significant concern due to the lack of a cure, while MRSA complicates the prevention of hospital-acquired infections, especially with healthy carriers.
• HCV poses a serious threat, potentially causing chronic hepatitis, cirrhosis, and hepatoma, and is a greater concern than Hepatitis B Virus (HBV) due to established HBV prevention measures.

Impact:

• Improved understanding of HIV, MRSA, and HCV can lead to enhanced prevention strategies.
• Highlighting the risks for healthcare workers (doctors, nurses, clinical technologists) emphasizes the need for appropriate precautions.
• This research aims to strengthen measures against hazardous microorganisms, improving patient and healthcare worker safety.
