Your brother has the flu describe three steps you will take to prevent catching the flu from him and why

Influenza is one of the most common infectious diseases, it is responsible for flu's symptoms.Influenza is a highly contagious acute respiratory infectious disease caused by viruses of the genus Influenza.It evolves through epidemics that can be global when the responsible virus infects people who have never met before. We are talking about a pandemic.
To prevent catching flu from your brother here's three ways:
* First, do not breath the same air room as your brother (or the least possible), because the flu virus is transmittable by air.
* Second do not touch objects that your brother has touched before (because he usually sneezes in his hand and touches his mouth and nose, so he can transmit the virus by his hands)
* And finally, wash your hand carefully several times per day, specifically after visiting your brother.
