The flu virus takes hundreds of thousands of lives each year. In this issue we will talk about its causes, and how it threatens all of humanity.
Influenza is an infectious disease that is not only characterized by high fever, cough and other respiratory symptoms, but can also cause pneumonia, asthma and even heart failure. Despite the availability of preventive vaccinations, every year in different countries of the world the flu becomes a real epidemic. So, according to the World Health Organization, the death rate from this disease reaches 650 thousand people annually. Of course, most of them are people over 75 years old and children under five years old, and most people recover from the flu in just a few weeks without the help of doctors.
The spread of the flu virus, like most respiratory diseases, occurs through the air, through coughing and sneezing, but even a polluted surface can cause illness, provided that you later touch the eye or mouth. It is because of this, periodically in the world occur pandemics – epidemics that affect most of the population of the Earth. In the twentieth century, three such events happened: in 1918, when about 50 million people died, in 1957 with a figure of two million, and finally, in 1968, with a death rate of one million.
Of course, we could not get past the swine flu, which in 2009 was raging around the world and was also a pandemic that claimed about 400 thousand lives. Also, you probably heard about bird flu, which, basically, only birds are ill, but the media greatly inflated information about its danger to people. So far, there is no evidence of its transmission from person to person, and a small group of infected people worked in direct contact with an infected bird. The danger of both types of virus is the lack of control over agricultural enterprises, and almost zero immunity to swine and avian influenza in modern humans.
In conclusion, we would like to say about ways to combat this disease. Vaccination is sufficient to prevent vaccination, which is carried out annually in our country, and, importantly, free of charge. If we talk about treatment, then here are used antiviral drugs, which include amantadine or zanamivir, which we recommend to use only after consulting a doctor.
