What Are the Most Dangerous Diseases?
What are the most dangerous diseases? Heart disease is the number one killer, accounting for more than 12 per cent of all deaths. It is a mosquito-borne disease that is ten times more deadly than the seasonal flu. There are also deadly viruses such as HIV and COVID-19. In this article, we’ll cover HIV, Ebola, and Tuberculosis. These diseases can kill an entire population.
COVID-19 is 10 times more deadly than seasonal flu
The number of deaths due to COVID-19 is much higher than that from seasonal flu, but it is still too early to draw any definitive conclusions. Experts are working to determine the mortality rate, but it could be anywhere from 10 to 44 times greater than influenza. Some experts say that the higher mortality rate could be due to the different ways COVID-19 spreads, while others say that it is simply due to the fact that COVID-19 is a completely new virus.
The symptoms of seasonal flu typically include fever and body aches and spread through respiratory droplets. COVID-19, however, is not spread through respiratory droplets and is much more severe. Unlike the flu, COVID-19 does not have a seasonal influenza virus, which means that it is more common and spreads far more quickly. The virus is not as easy to detect, either, making it important to find a hospital immediately.
HIV is one of the deadliest viruses
HIV is a virus that targets the immune system and weakens the body’s defence against many infections and certain types of cancer. It weakens the immune system by destroying immune cells and compromising their functions. The virus is diagnosed as acquired immunodeficiency syndrome (AIDS) when it causes long-term and severe clinical manifestations. For example, HIV-positive people may develop recurring fever, body sores, and memory loss.
If you are not aware of your infection, you must undergo HIV testing immediately. Many people with HIV do not know they have the disease. In the U.S., about 14% of people with HIV are unaware of their infection. In this stage, HIV remains present in white blood cells, making it easier for it to spread from person to person. Although most people don’t experience symptoms during the first few months of infection, they may experience flu-like symptoms within two to four weeks of becoming infected. In spite of this, newly-infected people can still transmit the virus to others.
Ebola is a mosquito-borne disease
Although this virus is not a mosquito-borne disease, it is a serious illness. Symptoms include fever, joint pain, and lack of appetite. The disease causes 50% to 90% mortality. It has been endemic in parts of Africa for decades. In 1976, a small outbreak was discovered in the Democratic Republic of Congo, near the Ebola River. The outbreak in 2014-2016 was the largest since 1976 and began in Guinea. The disease eventually spread to Sierra Leone and Liberia.
Infected persons may contract Ebola by direct contact with the virus. Infection is also possible from contaminated objects or animal fluids. The disease is transmitted to humans through broken skin, the nose, and eyes. Contact with infected bats and bushmeat is also a risk factor. Luckily, the Ebola virus is not a mosquito-borne disease. However, mosquito bites are a serious risk.
Tuberculosis is the leading cause of death from a single infectious agent
While TB affects almost every part of the world, some areas are more affected than others. By 2020, the World Health Organization estimates that two-thirds of new cases will be in eight countries. These countries include India, China, Indonesia, the Philippines, and Pakistan. Nigeria had the highest burden of HIV-associated TB. Diagnosed in 85% of cases, TB is often curable with a six-month course of drugs. However, in countries with a high burden of TB, diagnosis has fallen drastically, particularly in countries with poor healthcare systems.
Although TB can be curable, if you do develop symptoms, talk to your healthcare provider to determine whether you are at risk. If you have any symptoms, including fever, chills, sore throat, and difficulty breathing, you should get tested to see if you’re contagious. TB can be treated successfully if caught early, but if left untreated, it can be fatal.
Respiratory cancer is the second leading cause of death from a single infectious agent
While the incidence of respiratory cancer is declining globally, it remains one of the leading causes of death from infectious agents. In fact, despite advances in medical technology and antimicrobial drugs, the mortality rate associated with infectious diseases is still high, with a staggering 2.7 million people dying from one infectious agent every year. These figures are even more disturbing considering that the causes of infectious death from cancer are often overlooked.
In sub-Saharan Africa, lung cancer is the leading cause of cancer deaths and precedes cervical cancer. According to the SEER database, lung cancer accounts for about 30% of all cancer deaths in the world. Furthermore, in low-income countries, the mortality rate from respiratory cancer is nearly twice that of the same type of disease in the same population. However, there is no definitive evidence about the role of race in survival.
Tuberculosis is primarily found in poor populations
People with tuberculosis should take extra precautions, including frequent cleaning and washing, as well as taking a number of antibiotics. Since the bacteria that cause tuberculosis are slow-growing, most antibiotics must be taken for a long time to kill them. In addition, the disease may become resistant to antibiotics if not completely eliminated. If left untreated, tuberculosis tends to recur.
Symptoms of tuberculosis may include coughing. Although this symptom is mild and reversible, infected people may mistake it for a common cold or asthma. Sometimes, they will produce small amounts of sputum that is streaked with blood. In rare cases, a person with tuberculosis may also experience a cold sweat during the night. Though night sweats may be indicative of tuberculosis, other conditions may also cause this symptom.
