|Signs and Symptoms||
Fever, runny nose, sore throat, diarrhea, coughing, vomiting, nausea, lethargy, myalgia, anorexia and dyspnea.
|Incubation Period||Estimated incubation period is unknown and could range from 1-7 days.|
|Prophylaxis||Antiviral chemoprophylaxis with antiviral drugs.|
Oseltamivir, Zanamivir for seven days after exposure.
Daily temperature recording.
|Emory Requirements||Report any exposures.|
|Laboratory Acquired Infections (LAIs)||No data available.|
|Sources||No data available.|

|BSL-2||Diagnostic laboratory work on clinical samples from suspected cases. All sample manipulations should be conducted inside a biosafety cabinet (BSC).|
|BSL-2+||Viral isolation on clinical specimens from suspected cases should be performed in a BSL-2 laboratory with BSL-3 practices.|
|ABSL-2||All animal work with Influenza A/H1N1.|
|Small||Notify others working in the lab. Allow aerosols to settle. Don appropriate PPE. Cover area of the spill with paper towels and apply an EPA registered disinfectant, working from the perimeter towards the center. Allow 30 minutes of contact time before disposal and cleanup of spill materials.|

|Mucous membrane||Flush eyes, mouth or nose for 15 minutes at eyewash station.|
|Other Exposures||Wash area with soap and water for 15 minutes.|
|Reporting||Immediately report incident to supervisor, complete an employee incident report in PeopleSoft.|

|Disinfection||70% ethanol, 5% Lysol, and 10% bleach.|
|Inactivation||Virions are sensitive to treatment with heat, lipid solvents, non-ionic detergents, formaldehyde, oxidizing agents. The infectivity is reduced after exposure to irradiation.|
|Survival Outside Host||Influenza viruses can remain infectious for about one week at human body temperature, over 30 days at 0°C (32°F), and indefinitely at very low temperatures.|
Personal Protective Equipment (PPE)
|PPE||Wear PPE according to the requirements of the lab and the protocol. This includes and is not limited to double-gloves, closed toed shoes, closed front gowns, and appropriate face and eye protection based on risk assessment. Wash hands with soap and water before and after removing gloves.|
Due to the modes of transmission, respirators may be required when working with Influenza A / H1N1. Fit testing and training is required annually per Emory’s Respiratory Program.
