What temperature do you incubate inoculations?
Therefore, 35 ˚C is an optimum temperature for incubation of inoculated ECEs, in inactivated AI (A/Chicken/ Iran/99/H9N2) vaccine production process and this optimization help reduce extra production costs and increase amount of vaccine output.
How does the influenza virus can be transmitted?
Most experts believe that flu viruses spread mainly by tiny droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby.

What happens when tubes are incubated for a long time or at higher temperature?
0.05 ml. approx. 8 U/ml. Mix, incubate for 15 min.
How long does influenza virus live on surfaces?
Flu viruses that are able to survive on surfaces outside of the body that will then get transferred to someone’s hands can live up to 24 hours. Although, infectious flu viruses can survive on tissues including your hands for only 15 minutes.
Does flu lead to ARDS?
Acute respiratory distress syndrome (ARDS) is a fatal complication of influenza infection. In this Review we provide an integrated model for its pathogenesis. ARDS involves damage to the epithelial–endothelial barrier, fluid leakage into the alveolar lumen, and respiratory insufficiency.
