How does the flu affect the community?
The substantial economic impact of influenza on society results primarily from lost work time and reduced productivity of patients and caregivers and increased use of medical resources. Additionally, since the 1980s, aging of the US population has meant rising influenza-related morbidity and mortality.
What is the best definition of a flu pandemic?
An influenza pandemic is a global outbreak of a new influenza A virus. Pandemics happen when new (novel) influenza A viruses emerge which are able to infect people easily and spread from person to person in an efficient and sustained way.
What is 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.
Can you get swine flu from eating pork?
Can people catch swine flu/variant flu from eating pork? Swine influenza has not been shown to be transmissible to people through eating properly handled and prepared pork (pig meat) or other products derived from pigs.
Is it pandemic or pandemic?
According to the Center for Disease Control and Prevention (CDC), the difference between an epidemic and a pandemic is that: Epidemic is a sudden outbreak of a disease in a certain geographical area. Pandemic is an outbreak of a disease that has spread across several countries or continents.
What is the mode of transmission of common cold?
The common cold is spread either by direct contact with infected secretions from contaminated surfaces or by inhaling the airborne virus after individuals sneeze or cough. Person-to-person transmission often occurs when an individual has a cold blow or touches their nose and then touches someone or something else.
Should influenza patients be isolated?
Patients with suspected or confirmed influenza should be isolated in a single patient room. When single room is not available, the patient should be assigned to the cohort room. Healthcare workers should wear masks when they enter rooms with patients suspected or confirmed influenza.
What is the difference between H5N1 and H1N1?
The H5N1 virus (red RNAs) is not transmissible among guinea pigs, while the H1N1 virus (green RNAs) has highly efficient transmission. Exchange of the H5N1 RNA coding for PA or NS from H1N1 produces a highly transmissible virus. Exchange of the H5N1 RNA coding for NA or M produces a less efficiently transmitted virus.
What is the difference between H1N1 and H2N2?
H1N1 is one of the more promiscuous. It can infect birds, people, pigs and horses. H2N2, on the other hand, only makes its way into people and birds. A family tree of influenza A shows how human viruses, red, are related to bird and swine flus.
