H1N1 1

H1N1, also known as swine flu, is a highly contagious respiratory disease in pigs caused by influenza A viruses that can spread from animals to humans. Symptoms include cough, fever, sore throat, myalgia, weakness and fatigue. It spreads through direct contact with infected animals or people, unhygienic food preparation if eating undercooked meat, and inhalation of aerosols from coughs or sneezes of infected individuals. Diagnosis involves rapid tests, viral culture, PCR and serologic testing. Treatment focuses on rest, hospitalization if severe, and prevention through vaccination and hygiene.

Swine Flu (H1N1- Influenza
A virus subtype)
•H1N1 influenza, referred to as swine flu, is a highly
contagious respiratory disease in pigs caused by one of
several swine influenza A viruses.
•Influenza, one of the most common infectious diseases,
is a highly contagious airborne disease that occurs in
seasonal epidemics and manifests as an acute febrile
illness with variable degrees of systemic symptoms.
Although the seasonal strains of influenza virus that
circulate in the annual influenza cycle constitute a
substantial public health concern, far more lethal
influenza strains than these have emerged
periodically.
Besides humans, influenza also infects a variety of
animal species; some of these influenza strains are
species-specific, but new strains may spread from
other animals to humans.
Incidence and Prevalence
(Global,National, and Recent)
Etiologic Agent Period of Communicability
Direct contact. Transmission of influenza from poultry
MODE or pigs to humans appears to occur predominantly as a
result of direct contact with infected animals.
OF Unhygienic food preparation. The risk is especially

TRANS- high during slaughter and preparation for consumption;


eating properly cooked meat poses nor risk.

MISSION Aerosol transmission. Influenza viruses spread from


human to human via aerosols created when an infected
individual coughs or sneezes; infection occurs after an
immunologically susceptible person inhales the aerosol;
if not neutralized by secretory antibodies, the virus
invades airway and respiratory tract cells.
Contact with contaminated objects. Contact with
excrement from infected or contaminated surfaces or
water are also considered mechanisms of infection.
Clinical Manifestation
The presentation of influenza virus infection varies; however, it usually
includes many of the symptoms described below.
Cough. Cough and other respiratory symptoms may be initially
minimal but frequently progress as the infection evolves; patient
may report nonproductive cough, cough-related pleuritic chest pain,
and dyspnea.
Fever. Fever may vary widely among patients, with some having low
fevers and other developing fevers as high as 1040F; some patients
report feeling feverish and feeling chills.
Sore throat. Sore throat may be severe and may last 3-5 days; the
sore throat may be a significant reason why patients seek medical
attention.
Myalgia. Myalgias are common and range from mild to severe.
Weakness. Weakness and severe fatigue may prevent patients from
performing their normal activities or work; patients report needing
additional sleep; in some cases, patients with influenza may be
bedridden.
