About a new weekly of a viral outbreak that broke out somewhere in the world. Of course, the internet plays an important role in what the viral outbreak seems to be an increase in the number of viral outbreaks in the world. However, the number of infections is even increasing.
Since the beginning of 2018, Nigeria has been stricken with haemorrhagic fever caused by Lassa virus. More than 400 people were infected in July, 100 of whom died. In the Indian state of Kerala, an epidemic of Nipah virus, a virus that ignites the brain, killed 14 people in May. In Brazil, the yellow fever epidemic has reached extremely populated areas such as São Paulo and Rio de Janeiro. About 723 people were infected and a quarter of them died.
In a way, we are more aware of the danger of these outbreaks, after Ebola killed more than 11,000 people between 2014 and 2016, and Zika resulted in the birth of 3,500 children with the nervous system destroyed between 2015 and 2017.
New viruses appear all the time and we do not have many of them
Reports show that four new species of human viruses are discovered each year. In addition, scientists believe that we still have 250 new viruses discovered. However, the process of finding a new virus is extremely complex. Involves the description of the entire genetic code of the virus, its molecular sequencing, and computer tests using basic data.
Subsequently, epidemiological medical studies aimed at spreading diseases in parallel with biological experiments aim to understand the dangerousness of a virus for humans. To learn this, it can take years. An example is parvoviruses. They were discovered in the 1950s. However, it was only in 2004 that scientists discovered that they were responsible for the deaths of many children.
People have their part to blame for viral epidemics
To survive, viruses need a host body. The United Nations has estimated that the world population increases by 1% from one year to the next, which gives more viruses to the hosts. In addition, the trend towards urbanization makes people closer to each other, which facilitates the spread of viruses.
People are also expanding their settlements in order to catch the growing number of people in previously wild areas. Thus, they come into contact with new viruses, which are passed from animals to humans. For example, the flu virus was first transmitted to poultry.
Viruses are as good as they can, and that does not help
Many viruses can go unnoticed for long periods of time, but remain highly transmissible at that time when they are hidden. For example, the Ebola virus remains somewhat incognito for several months, during which it affects very badly the sexual organs, the brain or the eyes.
The HIV virus can also remain hidden for years in a person, and he can pass it on without even doing it.
There are no specific drugs for the most dangerous viruses that affect people. The reason is that viruses are part of an extremely large, diverse and growing group. In addition, the ability of virus adaptation can often lead to resistance to a particular treatment. Thus, a single drug can not be effective for all viral threats, as with antibiotics with bacteria.
The fight against viruses is far from over – it's pretty clear. The only hope is that the tricks of viruses are incomparable with the immense intelligence of scientists struggling to catch up with them every day.
