What factors can cause flu pandemic?

The potential of influenza pandemic has remained one of the most common health problems since the 20th century. Such a focus is the result of massive, often global spread of influenza virus. Although advances in medical technology have somewhat shortened these events, scientists still estimate that influenza pandemic will occur about three times every century. Several factors intertwine to create conditions for pandemia: animals, viral mutations and scientific and economic problems.

The flu pandemic occurs with different degrees of intensity. Many cases simply lead to an increased number of influenza cases on a large scale. However, the outbreak can occasionally lead to a deadly disaster. Perhaps the most notorious flu pandemic in modern times appeared during the Spanish outbreak of the flu from 1918. This particular pandemic required more than 50 million lives around the world. And animal infection serves as genesis for most influenza pandemics. Because the influenza virus has been treated with vaccines and other summer for many yearsKařských drugs, the virus constantly develops new ways to adapt, and thus resist these treatment. As a result, the virus is constantly developing on new tribes. When one of these strains develops resistance to traditional flu fighters, the foundations were laid for extensive outbreaks. Many scientists believe that certain types of influenza virus, such as the H5N1 tribe, have greater potential for more serious mutation.

A large percentage of mutated influenza viruses starts in other animals than in humans precisely because they do not have advanced resistance to influenza viruses. These mutations can then grow and spread unauthorized between the animal population. Some animals seem to have higher susceptibility to new influenza errors. Commonmed creatures include pigs and birds, especially ducks and chickens.

Pandemia begins seriously when animal flu virus is transmitted by people, usually by bite, scratch or contact with animals. Even whenThese cases may occur in isolated cases, the spread of the virus to humans is likely to be fast due to the immunity of the virus against influenza shots or other preventive measures. Depending on the strength and efficiency of the virus, the outbreak can escalate into a fully blown pandemic before it is possible to perform a suitable action.

As a result of technological progress, scientists can often predict whether a new influenza tribe has a virus pandemic potential. Government and medical officials can therefore take steps to control the spread of suspicious viruses of influenza. Pandemia often adheres when infected areas are poorly equipped for proper behavior, usually due to the economic disadvantage or lack of resources and readiness. The two most common retaliation of the event against the flu pandemia are quarantine and the development of the vaccine.

In cooperation with local officials, the country of the country can close areas where infections or many infections have begun from other regions. On a smaller scale, the hospital can also insert infected patients into quarantine orisolation. While the spread is contained, medical staff is entrusted with the treatment of infected. Meanwhile, scientists study the virus of mutated flu and work on drug development or vaccines that can break its resistance.

Scientists and doctors from around the world work every day to prevent another flu epidemic. In fact, influenza is one of the primary duties of the world health organization. This group classifies and monitors the potential threats and distributes the influenza educational materials for public consumption.

Understanding and treatment of influenza is an important step in combating sickness -free potential. The virus creates an infectious disease that spreads between mammals. Common symptoms of influenza infection are fever, muscle pain, headache, cough, sore throat and general weakness. The infection is transmitted by body fluids, air through cough or sneezing, or sometimes contact with a surface that has traces of virus. The flu is perhaps the most effective weapon against the flu, especially for someRych sub -groups such as small children, older people or individuals with a weakened immune system.
