Besides bacteria, viruses are also an important cause of nosocomial infection. Usual monitoring revealed that 5% of all the nosocomial infections are because of viruses [21]. They can be transmitted through hand-mouth, respiratory route and fecal-oral route [22].

What are the types of nosocomial infection?

Pathogens responsible for nosocomial infections include bacteria, viruses, and fungi….Types of Healthcare-Associated Infection (HAI)

  • Central line-associated bloodstream infections (CLABSI)
  • Catheter-associated urinary tract infections (CAUTI)
  • Surgical site infections (SSI)
  • Ventilator-associated pneumonia (VAP)

How do these communicable diseases spread?

  • physical contact with an infected person, such as through touch (staphylococcus), sexual intercourse (gonorrhea, HIV), fecal/oral transmission (hepatitis A), or droplets (influenza, TB)
  • contact with a contaminated surface or object (Norwalk virus), food (salmonella, E.

How are nosocomial infections diagnosed?

How are nosocomial infections diagnosed? Many doctors can diagnose a HAI by sight and symptoms alone. Inflammation and/or a rash at the site of infection can also be an indication. Infections prior to your stay that become complicated don’t count as HAIs.

What are the modes of disease transmission?

The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle. The portal of entry is the means by which the infectious microorganisms gains access into the new host.

What are the risk factors of nosocomial infection?

Risk factors for nosocomial infection were recorded as age, sex, cause of admission to the ICU, the Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients on admission to the ICU, any underlying diseases, surgical history, use of H2 receptor antagonists, central and/or peripheral intravenous …

How are protozoa helpful to humans?

They live in water or at least where it is damp. Some protozoans are harmful to man because they can cause serious diseases. Others are helpful because they eat harmful bacteria and are food for fish and other animals.

What is a hospital-acquired infection called?

Hospital-acquired infections, also known as healthcare-associated infections (HAI), are nosocomially acquired infections that are typically not present or might be incubating at the time of admission. These infections are usually acquired after hospitalization and manifest 48 hours after admission to the hospital.

Which disease is caused by protozoan Leishmania?

Leishmaniasis is caused by a protozoa parasite from over 20 Leishmania species. Over 90 sandfly species are known to transmit Leishmania parasites. There are 3 main forms of the disease: Visceral leishmaniasis (VL), also known as kala-azar is fatal if left untreated in over 95% of cases.

How can hospital-acquired infection be reduced?

  1. Wash Your Hands. Hand washing should be the cornerstone of reducing HAIs.
  2. Create an Infection-Control Policy.
  3. Identify Contagions ASAP.
  4. Provide Infection Control Education.
  5. Use Gloves.
  6. Provide Isolation-Appropriate Personal Protective Equipment.
  7. Disinfect and Keep Surfaces Clean.
  8. Prevent Patients From Walking Barefoot.

Some well known nosocomial infections include: ventilator-associated pneumonia, Methicillin resistant Staphylococcus aureus, Candida albicans, Acinetobacter baumannii, Clostridium difficile, Tuberculosis, Urinary tract infection, Vancomycin-resistant Enterococcus and Legionnaires’ disease.

What medicine kills protozoa?

Antimalarial drugs include mefloquine, chloroquine, proguanil with atovaquone and doxycycline. They kill or inhibit the growth of protozoa by affecting different stage of the parasitic life cycle. They are used both to treat and prevent malaria.

What are the main routes infection can enter the body?

Pathogens can enter the body by coming into contact with broken skin, being breathed in or eaten, coming into contact with the eyes, nose and mouth or, for example when needles or catheters are inserted.
