The vaccine is expected to be available to the public in October of this year. One also needs protection against the regular flu virus which shows up every winter. It is unlikely there will be enough vaccine to vaccinate the entire world population. Pregnant women, children, young adults, healthcare professionals engaged in patient care, military personnel all should get priority.
Public need to remember that every year seasonal influenza causes 30,000 deaths in America especially the elderly with chronic lung disease, heart disease and kidney disease. Death generally happens only when there is severe involvement of both lungs by what is called acute lung injury or acute respiratory distress syndrome. With modern medical amenities, 42 percent of such cases can be saved.
Two classes of drugs are available to minimize the effects of flu on the body. They are Tamiflu (Oseltamivir) and Relenza (Zanamivir). Recently, Japanese scientists have successfully tested CS-8959 in a clinical trial. This drug may be released for public use in Japan next year. This is found to be safer and more efficacious than Tamiflu.
According to a British Medical Journal report, children under the age of 12 should not be given Tamiflu or Relenza. These drugs reduced the length of the flu infection by only one day. More importantly these drugs reduced the transmission of the virus only by eight percent.
The Mexican experience has also revealed the effectiveness of personal protective equipment, to prevent the infection of health care workers. Doctors and nurses taking care of critically ill patients should be given N 95 masks for their safety.
So many people are dying everyday from dengue fever, malaria, tuberculosis and various bacterial and viral infections. Yet, the media by heightening awareness about the disease has unwittingly engendered undue public anxiety.
