Viruses & Bacteria

Let’s delve into the fascinating world of viruses and bacteria.

  • Definition: Viruses are tiny infectious agents that cannot survive or reproduce independently. They lack cellular structures and are composed of genetic material (either DNA or RNA) surrounded by a protein coat called a capsid.
  • Characteristics:
  • a) Non-living: Viruses are not considered living organisms because they cannot carry out metabolic processes on their own.
    b) Obligate parasites: They rely on host cells to replicate and multiply.
    c) Specificity: Each virus has a specific host range (e.g., human, animal, plant) and targets specific cells.
    d) Infectious: Viruses cause diseases by invading host cells and hijacking their machinery.
  • Examples: Influenza virus, HIV, SARS-CoV-2 (responsible for COVID-19).

  • Bacteria:
  • Definition: Bacteria are single-celled microorganisms with a simple structure. They have a cell wall, cell membrane, cytoplasm, and genetic material (DNA).
  • Characteristics:
  • a) Living organisms: Bacteria are considered living because they can carry out metabolic processes independently.
    b) Diverse: Bacteria come in various shapes (e.g., cocci, bacilli, spirilla) and can thrive in different environments.
    c) Beneficial and harmful: While some bacteria are essential for processes like digestion and nitrogen fixation, others cause diseases.
    d) Reproduction: Bacteria reproduce through binary fission.
  • Examples: E. coli (found in the gut), Streptococcus (causes strep throat), Staphylococcus (can cause skin infections).

  • Indoor Contamination:
  • Both viruses and bacteria can be present indoors:
  • a) Sources: They originate from human occupants, pets, and the outdoor environment.
    b) Locations: They exist on surfaces, as suspended particles, or as bioaerosols in indoor air.
  • Health Risks:
  • a) Bacteria: Some bacteria can cause infections, food poisoning, or skin conditions.
    b) Viruses: Viral particles can remain suspended in the air and pose a risk of transmission.
    c) COVID-19: The pandemic has highlighted the importance of indoor air quality and hygiene.

    Mitigation Strategies:
  • Regular cleaning and disinfection.
  • Proper ventilation.
  • Professional disinfection services.

  • Treatment and Disinfection Services:
  • Professional Disinfection Services:
  • a) These services use approved chemicals and methods to eliminate harmful microbes.
    b) Authorized by KKM (Malaysia’s Ministry of Health) and certified Halal.
    c) Effective against viruses like COVID-19.
    d) Available for both residential and commercial spaces.
  • Methods:
  • a) Disinfection Misting: Efficiently delivers virucides to surfaces.
    b) Pressure Spraying: Directly applies disinfectant to targeted areas.
    c) Surface Wiping: Uses high-level disinfectants to kill viruses on surfaces.

    Remember, maintaining a clean and hygienic indoor environment is crucial for our well-being. If you need professional disinfection services, consider reaching out to experts who follow safety guidelines and use effective methods.
