A propósito de la gripe pandémica
Influenza is a disease caused by a highly infectious virus that spreads easily from person to person, primarily when an infected individual coughs or sneezes. An influenza pandemic is a global epidemic of an especially virulent virus, newly infectious for humans, and for which there is no preexisting immunity. This is why these pandemic strains have such potential to cause severe morbidity and mortality. According to the World Health Organization (WHO), the next pandemic is likely to result in 1 to 2.3 million hospitalizations and 280,000 to 650,000 deaths in industrialized nations alone. Its impact is expected to be even more devastating in developing countries. In an attempt to minimize the impact of a pandemic, many countries are developing national and transnational plans against an eventual influenza pandemic situation.
