Know the Difference between Cold and Swine Flu Symptoms
Symptom Cold Swine Flu
Fever Fever is rare with a cold.
Fever is usually present with theflu in up to 80% of all flu cases.
A temperature of 100F orhigher for 3 to 4 days isassociated with the flu.
Coughing
A hacing! productive"mucus# producing$ coughis often present with acold.
A non#productive "non#mucusproducing$ cough is usuallypresent with the flu "sometimesreferred to as dry cough$.
Acheslight &ody aches and
pains can &e part of a cold.
evere aches and pains are
common with the flu.
Stuffy Nose

/ecommendations to prevent spread of the virus among humans includeusing standard infection control against influen+a. *his includes freLuentwashing of hands with soap and water or with alcohol#&ased handsaniti+ers! especially after &eing out in pu&lic.98,:'hance of transmissionis also reduced &y disinfecting household surfaces! which can &e done
effectively with a diluted chlorine &leach solution.983:

Alcohol#&ased gel or foam hand saniti+erswor well to destroy
viruses and &acteria. Anyone with flu#lie symptoms such as a suddenfever! cough or muscle aches should stay away from wor or pu&lictransportation and should contact a doctor for advice.
ocial distancingis another tactic. 6t means staying away from otherpeople who might &e infected and can include avoiding large gatherings!spreading out a little at wor! or perhaps staying home and lying low if aninfection is spreading in a community. ;u&lic healthand other responsi&leauthorities have action plans which may reLuest or reLuire social
distancing actions depending on the severity of the out&rea.

As swine influen+a is rarely fatal to pigs! little treatment &eyond rest andsupportive care is reLuired.924:6nstead veterinary efforts are focused onpreventing the spread of the virus throughout the farm! or to otherfarms.911:accination and animal management techniLues are mostimportant in these efforts.
