Influenza


Influenza, commonly known as “Flu”, is an infectious disease of birds and mammals caused by RNA viruses of the Orthomyxoviridae family, or is also known as the flu virus. The most common symptoms are chills, fever, runny nose, sore throat, muscle aches, headache, cough, weakness, fatigue, and general malaise. It is common to say that you have the flu when in reality what you are suffering from is a common cold, which comes with symptoms similar to those of the flu but much less strongly than the flu or influenza. The flu is a more serious illness caused by a different type of virus. Influenza can cause nausea and vomiting, especially in children, but these symptoms are more common in related gastroenteritis, which is sometimes mistakenly referred to as the “stomach flu” or “24-hour flu.”

The flu can occasionally lead to pneumonia, direct viral pneumonia or secondary bacterial pneumonia. These types of conditions can be controlled with the appropriate treatment, but in the case of bacterial pneumonia, the patient may relapse into an even greater complication. Constant monitoring of the patient should be applied.

Influenza is usually spread through the air by coughing or sneezing. Influenza can also be spread by direct contact with bird droppings or nasal secretions, or by contact with contaminated surfaces. Many types of flu can be deactivated thanks to some type of antibacterial detergent which acts as a protection.

Influenza has a stationary behavior, except when it spreads and becomes a pandemic, the most dangerous flus are those that are transmitted from animals to humans, the world in recent years has had to survive two strong influenza that have killed to millions of human beings, we refer of course to the flu or avian influenza (H5N1) and the most recent that is still plaguing Latin American countries: the flu or swine influenza (H1N1). The vaccine for these influenzas has already been developed, but access to it is regulated by the governments of the most affected countries, which makes it difficult to administer it correctly and adequately in order to control the situation.
