Fusion glycoprotein trimer, Human parainfluenza virus 3 (HPIV3). The viruses can be detected via cell culture , immunofluorescent microscopy , and PCR . [ 4 ] HPIVs remain the second main cause of hospitalisation in children under 5 years of age for a respiratory illness (only respiratory syncytial virus (RSV) causes more respiratory ...
Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
H. parainfluenzae biotypes I and II are capable of natural genetic transformation. [3] Natural genetic transformation is a bacterial adaptation for DNA transfer. In order for a bacterium to bind, take up and recombine exogenous DNA into its genome it must enter a special physiological state termed natural competence.
H. influenzae is a small Gram-negative bacterium, approximately 0.3 micrometer to 1 micrometer. [12] Like other Gram-negative bacteria, H. influenzae has a thin peptidoglycan layer surrounded by an outer membrane containing lipopolysaccharide. [13]

3–5 million severe cases per year [1] [2] Deaths >290,000–650,000 deaths per year [3] [4] Influenza, commonly known as the flu, is an infectious disease caused by ...
The two most common respiratory pathogens to which air passengers are exposed are parainfluenza and influenza. [4] In one study, the flight ban imposed following the attacks of September 11, 2001 was found to have restricted the global spread of seasonal influenza, resulting in a much milder influenza season that year, [ 5 ] and the ability of ...
Universal precautions are an infection control practice. Under universal precautions all patients were considered to be possible carriers of blood-borne pathogens. The guideline recommended wearing gloves when collecting or handling blood and body fluids contaminated with blood, wearing face shields when there was danger of blood splashing on mucous membranes ,and disposing of all needles and ...
