Bird flu raises worries after study points to human transmission
As public health officials around the world monitor the status of H7N9 influenza, that strain and others continue their evolution. The very nature of the influenza virus is that it is constantly changing, emerging in a particular host then evolving so it can infect another animal – or human. The danger increases when human-to-human transmission becomes routine.
The flu is communicable before symptoms emerge. Someone who has been exposed can infect others before anyone knows the illness is present. How then, do we prepare for a disease that can be deadly before it is evident? Maintaining health is a first step. Proper diet, rest, and exercise are perennial good advice. Health authorities strive to produce vaccines against the prevalent strains of influenza each year, staying current with immunizations enhances protection. Awareness can keep you healthy, your family safe, and your business vital.
Travel to a region where H7N9– or any other infectious disease – is present or visits from such a region should prompt subsequent monitoring for flu-like symptoms. Signs of sickness should prompt a visit to a physician.
Knowing how and when to avoid exposure, and what to do if it occurs, can be life-saving.
