Common diseases caused by bacteria and viruses




















A virus is a micro organism and it is usually very difficult to kill. Usually, viruses and bacteria can cause diseases. Bacteria are larger and capable of reproducing on themselves while viruses are much smaller and are not capable of reproducing on their own. A virus reproduces inside the living cell of the host. Bacteria can reside in any location or climate on earth.

Also, it can live on or inside animals, people, and plants. Bacteria that cause diseases are known as Pathogenic Bacteria. They produce poisonous substances called Exotoxins and Endotoxins that present various mild to serious symptoms.

Below is the list of some human diseases caused by Bacteria. Pneumonia is caused by bacteria called Streptococcus Pneumonia. The infection usually starts when the bacteria are inhaled and reproduces themselves at a rapid rate in the lungs. If it becomes pathogenic, it results in pneumonia. Streptococcus Pneumonia is usually cocci shaped bacteria.

Most common symptoms of pneumonia include coughing, high fever, and difficulties breathing among others. Pneumonia is mostly treated with antibiotics.

A pneumococcal vaccine helps to protect against the development of this disease. Once infected, the common symptoms are diarrhea, dehydration, muscle cramps, rapid heart rate, low blood pressure, loss of skin elasticity, and excessive thirst.

Without proper treatment, death can occur within just a few hours CDC, Escherichia Coli, more commonly known as E. Coli, is a type of bacteria that lives in the intestines of humans and animals. Though most strains of e. Coli, which infects around , people and kills 90 every year in the US. Once infected, symptoms usually start within days of exposure and can include abdominal pain, diarrhea, vomiting, and fever.

Those with healthy immune systems usually heal within 5 to 7 days. If left untreated, those with compromised immune systems can escalate into dehydration, intestinal infection, kidney failure, and death.

The disease is usually transmitted through unsafe handling of food and through contaminated water. Poor sanitation can move bacteria from humans or animals into the water stream CDC, Waterborne pathogens are everywhere but it is up to us to ensure we take the proper precautions to reduce the risk of exposure.

One crack in a water pipe can put the entire water supply at risk of exposure. When traveling, camping, or preparing for water storage at home, proper knowledge of the potential risks at hand is essential. When overseas, only drink water from trusted, properly sealed bottled sources. When unsure of the quality of a water source, always err on the side of caution and avoid it or apply the proper purification methods. Be aware and informed and keep yourselves and your family safe.

Protozoa are single-celled eukaryotes that feed on organic matter and can either be free-living or parasitic. They are similar to algae but too small to be seen without a microscope. Parasites are a type of protozoa which thrive at the expense of a host and usually dwell in fecal matter.

They can often live within a host undetected for long periods of time due to their resilient nature. Symptoms of Infectious Disease Many infectious diseases have similar symptoms, like: fever, diarrhea, fatigue, and muscle aches. Treatment for Infectious Disease Many infectious diseases can be treated by antibiotics specifically diseases caused by bacteria.

Hear From Our Specialists Jan 10, Jan 10, Jan 07, Person to person. Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn't infected. These germs can also spread through the exchange of body fluids from sexual contact.

The person who passes the germ may have no symptoms of the disease, but may simply be a carrier. Disease-causing organisms also can be passed by indirect contact. Many germs can linger on an inanimate object, such as a tabletop, doorknob or faucet handle. When you touch a doorknob handled by someone ill with the flu or a cold, for example, you can pick up the germs he or she left behind.

If you then touch your eyes, mouth or nose before washing your hands, you may become infected. Some germs rely on insect carriers — such as mosquitoes, fleas, lice or ticks — to move from host to host.

These carriers are known as vectors. Mosquitoes can carry the malaria parasite or West Nile virus. Deer ticks may carry the bacterium that causes Lyme disease. Disease-causing germs can also infect you through contaminated food and water. This mechanism of transmission allows germs to be spread to many people through a single source. Escherichia coli E. While anyone can catch infectious diseases, you may be more likely to get sick if your immune system isn't working properly.

This may occur if:. In addition, certain other medical conditions may predispose you to infection, including implanted medical devices, malnutrition and extremes of age, among others.

Most infectious diseases have only minor complications. But some infections — such as pneumonia, AIDS and meningitis — can become life-threatening.
