Is influenza airborne or droplet?
Influenza is thought to be transmitted primarily by droplets (particles ≥ 5 μm, and settling within 3-6 feet); however, the airborne route (particles < 5 μm remaining suspended in air) has been implicated in special situations, such as aerosol-generating procedures.
Is influenza airborne or droplet precautions?
Adherence to precautions. Influenza is usually transmitted through droplet of large particles generated by cough or sneezing of an influenza patient. In some cases, it can spread through smaller aerosols. Droplet can travel less than 1 m, and therefore it is spread by close contact.
What are the mode of transmission of influenza?
Influenza viruses are predominantly transmitted by airborne spread in aerosols, but can also be transferred by direct contact with droplets. Nasal inoculation after hand contamination with the virus is also an important mode of transmission, highlighting the critical importance of hand hygiene.
Is influenza direct or indirect transmission?
The influenza viruses can also be transmitted by indirect contact by touching a contaminated object or surface and then touching your own mouth, eyes or nose before washing your hands.
How long do flu droplets stay in the air?
Flu viruses can survive as droplets in the air for hours and on surfaces for up to a day but can only survive on tissues for 15 minutes (4). Bearing this in mind, if you do catch the flu: Use tissues to cover your mouth and nose when you cough or sneeze.
Do you wear an N95 for droplet precautions?
A respirator or N95 face mask is NOT necessary but can be used for the care of a patient on Droplet Precautions. Remember, that you should continue to use Standard Precautions during patient care in addition to Droplet Precautions. This includes handling items contaminated with the patient’s respiratory secretions.
What PPE is needed for droplet precautions?
If you are treating a patient in droplet precautions you need to wear a mask, gown and gloves.
What is the incubation period for influenza?
How long does it take to develop symptoms of influenza after being exposed? The incubation period of influenza is usually two days but can range from one to four days.
Does influenza spread easily?
The flu is far easier to spread, requiring no contact at all. It’s also possible to spread the flu via surface contact. If a sick person coughs into their hand and then touches a doorknob or other surface, those who touch that same surface after and then touch their face can become infected.
What disease does influenza cause?
Complications of flu can include bacterial pneumonia, ear infections, sinus infections and worsening of chronic medical conditions, such as congestive heart failure, asthma, or diabetes.
Is airborne transmission direct or indirect?
With airborne transmission, droplet nuclei remain airborne for long periods, may disseminate widely in an environment such as a hospital ward or an operating room, and can be acquired by (and infect) patients directly, or indirectly through contaminated medical devices.
How is influenza spread through direct contact?
Influenza virus may be transmitted among humans in three ways: (1) by direct contact with infected individuals; (2) by contact with contaminated objects (called fomites, such as toys, doorknobs); and (3) by inhalation of virus-laden aerosols.
Is it possible to catch influenza twice?
Yes, because the virus can mutate (change). If you become infected with the swine flu virus, your body produces antibodies against it, which will recognize and fight off the virus if the body ever meets it again.
