Hospital-acquired infections (HAIs) that spread quickly include C. diff, a bacteria causing severe diarrhea, and antibiotic-resistant germs like MRSA, while airborne viruses (flu, COVID) and fungi like Candida auris also spread rapidly via droplets or contaminated surfaces, preying on vulnerable patients. These spread through poor hygiene, contaminated equipment, or air, especially affecting weakened patients.
Listed below are the types of HAIs and some of the possible complications:
Most Common Viral Horse Diseases, Their Symptoms, And Treatment
According to certain analyses, surgical-site infections (SSIs) are some of the most common HAIs — potentially related to improper sterile procedures or follow-up care. However, another study indicates that hospital-acquired pneumonia (HAP) may affect the largest number of patients.

the air as small droplets (droplet spread) or tiny aerosol particles (airborne spread) contact with faeces (poo) and then with the mouth (faeco-oral spread) contact with the skin or mucus membranes (the thin moist lining of many parts of the body such as the nose, mouth, throat and genitals) (contact spread)
These include Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter species.
Tuberculosis is the deadliest infectious disease in the world. Why is it so dangerous, and what are the symptoms? A stubborn cough can be a sign of tuberculosis or TB. Tuberculosis is still around, and cases have been on the rise in recent years in Colorado and around the U.S. Photo: Getty Images.
Common bacterial diseases
Organisms
Common types include central line–associated bloodstream infections, catheter-associated urinary tract infections, surgical site infections, ventilator-associated pneumonia, and Clostridioides difficile infections.
A Brief Introduction to the Top 3
The top 3 bacterial infections are Strep Throat, Urinary Tract Infections (UTIs), and Bacterial Pneumonia.
Some patients are at greater risk than others-young children, the elderly, and persons with compromised immune systems are more likely to get an infection. Other risk factors are long hospital stays, the use of indwelling catheters, failure of healthcare workers to wash their hands, and overuse of antibiotics.
Below are five examples of hospital-acquired infections, including information about their symptoms and risks.
Definition: Hospital-acquired infections (or healthcare-associated infections) are infections that occur after a patient is admitted to a hospital or any healthcare facility and that were not present at the time of admission.
Contact transmission
This is the most important and frequent mode of transmission in the health care setting. Organisms are transferred through direct contact between an infected or colonized patient and a susceptible health care worker or another person.
MRSA is one of the most common antibiotic-resistant bacteria. Symptoms of MRSA infection often begin as small red bumps on the skin that can progress to deep, painful abscesses or boils, which are pus-filled masses under the skin.
However, over the past 25 y it has been shown that gram-positive bacteria are the most common cause of sepsis. Some of the most frequently isolated bacteria in sepsis are Staphylococcus aureus (S. aureus), Streptococcus pyogenes (S. pyogenes), Klebsiella spp., Escherichia coli (E.
Viral infections often develop gradually, such as a cold that starts with a scratchy throat and progresses to a cough and congestion. Bacterial infections, however, tend to appear suddenly and with more intensity. For example, strep throat can cause a severe sore throat and high fever that comes on quickly.
Necrotizing Fasciitis
This is a very dangerous bacterial skin infection that can kill the victim within a short period of time. It is popularly known as flesh eating bug because of its ability to speedily spread through the body and kill the body's soft tissue.
Rabies virus has a characteristic bullet-shaped virion structure. Rabies virus infection in mammals is nearly 100% fatal if left untreated.
"Big Three" Infectious Diseases: Tuberculosis, Malaria and HIV/AIDS.
Methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa and other non-pseudomonal Gram-negative bacteria are the most common causes. Hospital-acquired pneumonia is estimated to increase hospital stay by about 8 days and has a reported morality rate that ranges from 30 to 70%.
Patients are admitted to the hospital for a variety of reasons. Among the most serious are potentially life-threatening bacterial infections. Examples include pneumonia, sepsis, intra-abdominal infection, endocarditis, staphylococcal skin infection, and infections caused by multidrug-resistant pathogens.
Gram-negative enteric organisms accounted for about 50% of all urinary tract infections. The top 3 pathogens for surgical site infections were S aureus (20%), P aeruginosa (15%), and coagulase-negative staphylococci (14%). Methicillin-resistant Staphylococcus aureus (MRSA) has become a prevalent cause of infections.
