5 Most Dangerous and Deadly viruses in the world!

Top 5 Most Deadly Virus around the world!

5. Lassa virus

A nurse in Nigeria was the first person to be infected with the Lassa virus. The virus is transmitted by rodents. Cases can be endemic - which means the virus occurs in a specific region, such as in western Africa, and can reoccur there at any time. Scientists assume that 15 percent of rodents in western Africa carry the virus.

4. Bird flu virus

The various strains of bird flu regularly cause panic - which is perhaps justified because the mortality rate is 70 percent. But in fact the risk of contracting the H5N1 strain - one of the best known - is quite low. You can only be infected through direct contact with poultry. It is said this explains why most cases appear in Asia, where people often live close to chickens.

3. Hantavirus

The Hantavirus describes several types of viruses. It is named after a river where American soldiers were first thought to have been infected with the Hantavirus, during the Korean War in 1950. Symptoms include lung disease, fever and kidney failure.

2. Ebola

There are five strains of the Ebola virus, each named after countries and regions in Africa: Zaire, Sudan, Tai Forest, Bundibugyo and Reston. The Zaire Ebola virus is the deadliest, with a mortality rate of 90 percent. It is the strain currently spreading through Guinea, Sierra Leone and Liberia, and beyond. Scientists say flying foxes probably brought the Zaire Ebola virus into cities.

1. Marburg virus

The most dangerous virus is the Marburg virus. It is named after a small and idyllic town on the river Lahn - but that has nothing to do with the disease itself. The Marburg virus is a hemorrhagic fever virus. As with Ebola, the Marburg virus causes convulsions and bleeding of mucous membranes, skin and organs. It has a fatality rate of 90 percent.

Two main types of glands in the human body

There are two main types of glands in the human body: exocrine glands and endocrine glands. The main difference between these two types of glands is that exocrine glands secrete their products into ducts that lead to body cavities, internal organs, or the body's outer surface, while endocrine glands secrete hormones directly into the bloodstream. Examples of exocrine glands include sweat glands, salivary glands, mammary glands, and sebaceous glands. Examples of endocrine glands include the pituitary gland, thyroid gland, pancreas, and adrenal glands. These glands are responsible for regulating a host of bodily functions such as metabolism, blood pressure, and reproductive processes. Additionally, there are also other types of specialized glands, such as lacrimal glands (which produce tears), ceruminous glands (which produce earwax), and mucous glands (which produce mucus).

How do government regulations protect the environment?

Government regulations can protect the environment in several ways. Limiting the release of pollutants: Environmental regulations often place limits on the amount of pollutants that businesses and industries are allowed to release into the air, water, or soil. This helps to reduce pollution levels and protect the health of both humans and wildlife. Setting efficiency standards: Regulations can require industries to follow specific efficiency standards, such as reducing energy use or using more sustainable production methods. This can help reduce resource consumption and minimize the environmental impacts of production. Promoting conservation and preservation: Governments can establish laws and regulations to protect natural areas, such as national parks or wildlife reserves, from development or destruction.
