“Top 7 Deadly Viruses in the World Without A Vaccine Yet”

Viruses and the importance of knowing how to protect yourself from them have been on everyone’s lips due to the very recent global pandemic caused by COVID-19. The general population has been on alert for all the complications that have come with this new virus.

In biology, there are a series of microorganisms that are usually infectious, which can cause negative repercussions in a living organism, that is, viruses. These viruses, according to National Human Genome They are made up of a core of nucleic acid, which is DNA or RNA, which is surrounded by a protein membrane.

The danger of these microscopic agents is that they do not have the ability to reproduce on their own, they must find a host to take and infect their organism, this to seize the components of the host’s healthy cells and use them to make copies of the virus itself. .

At present, the research and development of vaccines that protect us against these microorganisms are constantly being updated, and although there have been many advances, there are still viruses that do not have a vaccine and can be very dangerous if the necessary care is not taken, even reaching to cause a new global health emergency.

Currently, the World Health Organization has classified seven viruses that do not yet have a finished vaccine, which, although they have been discovered for a long time, have only recently evolved in these viruses, causing massive infections in humans. .

Ebola: disease first detected in 1976 in Africa.

This causes high fever in a high way

• Headaches
• Stomachache
• Sore throat
• extreme fatigue
• Vomiting and/or diarrhea
• absence of hunger
• In advanced cases internal and external bleeding, being fatal to the host.

Currently, they are looking to develop a couple of vaccines.

bird flu: this virus is of greater risk for birds, but there are also infections in humans. It is normal for this contagion to occur thanks to direct contact with birds that are carriers.

The symptoms that appear after a few days of contagion are the same as those of a common cold:

• Tos
• Fever
• Headache
• Sore throat
• inconvenience to breathe
• Muscle pains

This virus can become fatal if it is not treated in the first days of the onset of symptoms.

Middle East Respiratory Syndrome or MERS-coV: This virus is part of the coronavirus family, the current list of viruses that we’ve heard a lot about, thanks to COVID-19. This has a symptomatology that goes from:

• Tos
• Fever
• Diarrhea
• Pneumonia.

Severe Acute Respiratory Syndrome SARS: it also shares similarities with the current virus that is attacking globally, making it part of the Coronavirus family. Your symptoms are:

• Fever
• Dry cough
• Headaches and muscle pain
• Trouble breathing.

Nipah: This is one of the most recently discovered viruses, it emerged in Southeast Asia thanks to fruit bats. This disease do present:

• breathing difficulties
• Fever
• Headache and throat
• nausea
• vomiting

Marburg fever: virus identified in 1967 in Germany and Serbia, distributed directly by fruit bats or by some of their fluids. This is identified by fever initially, accompanied by:

• gastrointestinal upset
• bleeding
• Finally, multiple organ failure.

Crimea-Congo Fever: Discovered in 1944, this disease is transmitted by ticks or by having contact with infected tissue. Symptoms appear almost immediately:

• Fever
• Dolor muscular
• dizziness
• neck difficulties
• Eye irritation and hypersensitivity to light.

Of all the viruses mentioned, none has a vaccine that has a high percentage of effectiveness, however, hard work continues so that health lasts and their development is completed.
