9 of the most dangerous infectious diseases

5- Cholera:

fatal infectious diseases

Cholera is one of the most contagious diseases that can be passed easily through contaminated food and water. Historically, cholera has ravaged local communities, killing half of them. Until now, cholera can kill nearly 120,000 people a year. It was killing millions.

Cholera kills through rapid dehydration. Symptoms are nonstop vomiting and persistent diarrhea until you can’t do more. By one estimate, patients can produce up to 20 liters (5 US gallons) of diarrhea per day. Cholera is easy to treat with fluids and electrolytes. When treated, only 1% of infected people can be killed, and without treatment there is a chance that more than 60% of infected people will die, and the most dangerous strains can be killed within two hours if the patient is left untreated.

4- Staphylococcus bacteria:

fatal infectious diseases

MRSA or methicillin-resistant Staphylococcus aureus is particularly frightening because it renders modern medicine ineffective. This disease had the ability in ancient times to infect farmers with all kinds of boils and hideous skin diseases, but this germ is more than just a skin infection it was known to kill in within 24 hours.

There are a number of MRSA strains with some being more lethal than others (ST1: USA400 and ST8: USA300), but they have one thing in common: they are resistant to a wide range of the most widely used antibiotics available to humans, and are not easily treatable.

MRSA-related conditions:

Necrotizing fasciitis: a condition that erodes the flesh and affects deeper layers of the skin.

Necrotizing pneumonia: a flesh-eroding infection of the lungs.

Osteomyelitis: A painful infection of the bone.

• Sepsis: It can be a fatal infection of the bloodstream
• Endocarditis: infection of the heart

Methicillin-resistant staphylococcus aureus (MRSA), one of the deadliest infectious diseases, can effectively eat away at your body with very few effective antibiotics and increasing resistance. use it.

3- Rabies:

fatal infectious diseases

Rabies is an infectious disease that is always fatal if the person is not treated immediately after the bite, and if intervention does not occur until after symptoms appear, there is an 8% chance of survival, and rabies kills around the world about 55,000 people, mostly in Africa and India, but is still present in the United States and Europe.

Rabies affects the central nervous system first and eventually leads to disease in the brain, resulting in death. Symptoms include acute pain, violent movements, and uncontrolled agitation (mania, water panic) and this is seen as a state of panic when the patient is given fluids to drink until When thirsty it causes painfully sharp spasms of the muscles in the throat.

Perhaps the most well-known symptom is foam in the mouth resulting from excessive saliva production, and the incubation period for rabies varies greatly from a few days to several years, and unfortunately once symptoms start, death occurs within (2-10) days, and rabies can be carried by animals. Warm-blooded, but in the vast majority of cases it is due to a dog bite.

2- Smallpox:

Smallpox may be one of the most horrible diseases of any disease, it may be a deadly contagious disease, and the traditional appearance is the body that is covered with smallpox (fluid-filled blisters), and this is not limited to the skin either but can occur in the mouth and throat, and the disease has been present Since 10,000 B.C. and has been alone responsible for 300 million deaths since 1800, while the death rate is only about a third, most survivors have some scars with other complications including blindness, and the number of deaths is high even though smallpox is highly contagious unbelievable.

The death rate depends on the type of disease, and among the four forms, malignant smallpox and hemorrhagic smallpox are usually fatal, and this is the most dangerous form of smallpox, and there are no ulcers of the skin, and instead there is bleeding under the skin that causes it to turn black, and therefore it is called black smallpox, and this type Smallpox will kill in about 6 days. The good news about the deadly smallpox is that it has been officially eradicated. The world has been free of smallpox since 1976 with the last recorded case of two-year-old Rahima in Bangladesh.

1- Bubonic plague:

The bubonic plague, called the Black Death, was a deadly contagious disease that swept through medieval Europe and killed an estimated 100 million people. There were other plague epidemics including one in the sixth century that killed 50 million people throughout the Roman Empire.

Plague is spread by bacteria carried by rat fleas, and unfortunately, it also kills them, and symptoms occur within (2-5) days of the bite, and at first the lymph nodes near the flea bite swell like golf balls, and other symptoms include convulsions, seizures and the possibility of vomiting blood, and gangrene that occurs In the extremities it can cause the fingers, toes and nose to turn black, and it can change the color of the skin, with severe pain due to the disintegrating skin on a living person.

The bubonic plague still exists and sporadic cases occur even in the USA, and there have been major outbreaks recently like the one in 1946, the good news (relatively) is that it can be treated effectively if antibiotics are given within 24 hours, otherwise The mortality rate is over 60%.
