Strains of the flu in humans, birds and animals are common. If you remember, back in 2005, there was an outbreak of Avian Flu and it caused many deaths among children and adults. The symptoms of this type of flu are typically cough, fever, sore throat, fever and conjunctivitis. If it happens to be a severe case, breathing problems and pnuemonia are possible and probable. In some cases, health officials have even noted that diarrhea and seizures can result. As with all illnesses, it is important to catch the symptoms as early as possible and to avoid passing the illness on to others. If you have any of the above symptoms, see your doctor promptly for treatment.
