Although social distancing and the use of antiviral medicines can be partially effective at slowing pandemic flu spread, vaccination remains the most effective means of pandemic influenza control, the authors conclude.
Two doses of vaccine, delivered three weeks apart, may be needed to confer adequate protection to the virus. Ira Longini and colleagues emphasized that a combination of factors—the availability of an effective vaccine to protect people against pandemic H1N1, coupled with the timing of the outbreak—will determine how quickly the pandemic can be slowed.
The researchers estimate that to bring the pandemic under control aggressive vaccination of the population must begin at least a month before it peaks, concentrating on children as much as possible.
Vaccination increases population-level immunity and lowers the effective reproductive number of the virus, which results in two main effects: slowing the spread of infection and reducing the height of the pandemic peak; and reducing the overall illness attack rate, hospitalizations and mortality.
Other key findings in the study: Longini and colleagues are considered among the world’s leading disease modeling experts.
The major two types of Swine influenza are influenza C. Influenza A is further classified into four major classes; H1N1, H1N2, H3N1, H3N2, and H2N3 (Stephenson, 7). This influenza is more contagious and dangerous for pigs because a considerable percentage of pigs die from swine flu disease every year.
Swine Flu is transmitted from one pig to another in many ways; by aerosols, through direct or indirect interaction, or contact with already infected pigs (Tasian, 8).They are part of the federal government’s Models of Infectious Disease Agent Study Network, an effort funded by the National Institute of General Medical Sciences at the National Institutes of Health.Funding for the study came from the National Institute of General Medical Sciences and the National Institute of Allergy and Infectious Diseases.The biggest victim of Swine Flu -- Youngsters: Swine flu does not infect every age group with the same sternness, severity, and complexity; its biggest victims have always been the young adults.This thing can be evidenced from the fact that most of the fatalities caused by swine flu in Mexico, Northern Ireland, Philippines, Japan, Taiwan, U. A, and many European countries were of youngsters (Tanaka, Niki, & Kokaze, 121).“Our estimates of pandemic H1N1 in households, schools and in the community places this virus in the higher range of transmissibility,” said Dr.Yang Yang, first author of the paper and a staff scientist at VIDI.This is because swine influenza virus was quite new in both these creatures (Tasian, 7).Origin of Swine Flu: Today, it is believed that pigs were the origin of this virus that caused the humans to be contaminated with it very badly.Every individual is equally exposed to swine flu when it spreads in the air, but some people may have a high degree of risk towards this virus.This high-risk group includes; heart, liver, and kidney disease patients, neurological disease patients, pregnant women, and the people over the age of 60.
