Infection control is the discipline concerned with preventing nosocomial or healthcare-associated infection, a practical (rather than academic) sub-discipline of epidemiology. It is an essential, though often underrecognized and undersupported, part of the infrastructure of health care. Infection control and hospital epidemiology are akin to public health practice, practiced within the confines of a particular health-care delivery system rather than directed at society as a whole. Anti-infective agents include antibiotics, antibacterials, antifungals, antivirals and antiprotozoals.[1]

Infection control addresses factors related to the spread of infections within the healthcare setting (whether patient-to-patient, from patients to staff and from staff to patients, or among-staff), including prevention (via hand hygiene/hand washing, cleaning/disinfection/sterilization, vaccination, surveillance), monitoring/investigation of demonstrated or suspected spread of infection within a particular health-care setting (surveillance and outbreak investigation), and management (interruption of outbreaks). It is on this basis that the common title being adopted within health care is "infection prevention and control." (got from google

Wine goes bad soon after opening because the ethanol CH3CH2OH dissolved in it reacts with oxygen O2 gas to form water and aqueou
bagirrra123 [75]

Answer:

We need 0.095 moles of ethanol

Explanation:

Step 1: Data given

Number of moles water = 0.095 moles

Step 2: The balanced equation

CH3CH2OH + O2 ⇒ H2O + CH3COOH

Step 3: Calculate moles of ethanol

For 1 mol ethanol we need 1 mol oxygen to produce 1 mol water and 1 mol acetic acid

For 0.095 moles water, we need 0.095 moles ethanol and 0.095 moles  oxygen

We need 0.095 moles of ethanol

what was the initial pressure of 14.8 mL of gas at 75.5 C , when it occupied a volume of 16.5 mL at 70.2 C and 101.3 kPa?
OLEGan [10]

Answer:

1038.96 kPa

Explanation:

We’ll use the ideal gas law; P1V1/T1 = P2V2/T2

P1*14.8/75.5 = 101.3*16.5/70.2

P1 = (101.3 * 16.5 * 75.5) / (70.2 *14.8)

P1 = 1038.96
