Millions of people around the world suffer from STDs. An STD is an infection transmitted through some form of sexual contact caused by bacteria, viruses or fungi. These types of illnesses may not be curable, but they can be treated. However, they can affect your daily life forever if left untreated. Some of them can even be considered deadly if not taken seriously. There are different types of STDs around the world. From bacterial to viral to fungal. This article will specifically cover the three types of STDs. Each type of STD will be examined and explained as to where it originated, what can be done to stop it from spreading, and if there are any treatments. Starting with bacterial STDs, also known as STIs or sexually transmitted infections, can include chlamydia, gonorrhea, and syphilis. Next, let's move on to viral STDs, including hepatitis B, herpes, HIV, and human papillomavirus (HPV). And finally fungal STDs which include parasites and yeast infections. Say no to plagiarism.

The structure of a bacteria is a gel-like substance composed of water, enzymes, nutrients, and gases. They contain all the cellular structures that real cells have but, as previously mentioned, they do not have a nucleus surrounded by a membrane. The reproduction of bacteria is caused by binary fission. During this phase, the chromosome copies itself and then forms two identical copies. The cell will grow and divide into two new daughter cells. These two daughter cells will be identical to the parent cell. This entire process can take place in less than five minutes, which can result in the formation of a bacterial colony. The lifespan of a bacteria can be determined by four factors. These factors include the lag phase, the logarithmic or exponential phase, the stationary phase and finally the death phase. During the lag phase, bacteria do not grow. What he does is he tries to adapt to his environment. It also tries to produce vitamins and amino acids which are used for division. Once this is done, they can make copies of their DNA. If the environment suits them, the latency phase can be very short and allow them to move on to the next phase. In the logarithmic or exponential phase, the bacteria will multiply rapidly. For some it may take minutes and for others it may take days. This is a previous mention under the name binary fission. In the stationary phase, the size of the bacteria will decrease due to the minimum space provided to grow. Finally, in the death phase, the bacteria dies because it loses all ability to reproduce. This, just like the previous phase, may take a few minutes or days. This will happen, however, if the bacteria has not yet found a new environment to reproduce in. One type of bacterial STD is Chlamydia. This bacterial STD or STI is preventable and is the result of the bacteria Chlamydia trachomatis which can only affect the urethra and cervix. This disease is common between the ages of fifteen and nineteen. This diseasemay, however, show no signs of symptoms. It may take several weeks to notice signs of Chlamydia. These signs may include pain during urination, pain during sex, abnormal discharge, frequent urge to urinate, and sometimes pelvic pain. Fortunately, this condition is also treatable. It can be treated with antibiotics. These medications can be 95% effective. But it will take time for the medicine to work, depending on how the disease progresses. Viral STDsA virus is a small infectious agent that replicates only within the living cells of an organism. They can infect all types of life forms. They can range from animals and plants to microorganisms in which they include bacteria and archaea. They cannot reproduce on their own. Most of these infectious agents contain RNA or DNA as their genetic material. Their nucleic acid can even be single or double standard. They also have something called virion. The virion is an infectious viral particle composed of nucleic acid and an outer protein coat. A single virus can contain enough RNA or DNA to encrypt up to four proteins. Other more complex viruses can encrypt up to one hundred to two hundred proteins. Reproduction of a virus can occur in two ways. One being the lytic cycle and the other being the lysogenic cycle. During the lytic cycle, the virus attaches to the host cell. Once attached, the nucleic acids take over the function of the host cell to produce multiple copies of itself, creating new viruses. As host cells fill with new viruses, they eventually burst. The host cell will eventually die and the virus is looking for a new host cell. However, during the lysogenic cycle, when the virus enters the host cell, it can remain inactive for years. During this time, the nucleic acid becomes part of the host cell's chromosomes but does not affect its functions. Once the viral acid becomes active, it will separate from the host's genetic material and take on its function of producing more virus cells and destroying the host cell. The lifespan of a virus strictly depends on the environment and the type of virus. Depending on the type of virus, its lifespan may depend. Some can last weeks, some a year, some can even last seconds. It is not known for certain how long a virus can last, but humidity plays an important role in its survival. A very well-known type of viral STD is HIV or human immunodeficiency virus. HIV can harm your immune system by essentially destroying all of the body's white blood cells that help fight infections. This exposes a person to many health problems. In some, but not all, cases, HIV can lead to AIDS. HIV is often transmitted during unprotected sex or sometimes through used or shared needles. A mother can also transmit HIV to her child during childbirth. The first symptoms of HIV may be swollen lymph nodes that may last for two to four weeks, but other serious symptoms may not appear until years later. There is no cure for this virus, but there are medications that can help fight HIV infections and reduce the risk of infecting others, but it is a lifelong medication. Fungal STDsA fungus is the plural form of mushroom. There are nearly 144,000 known species of mushrooms. This is any spore-producing organism that feeds on organic matter. They can live in many places,-20378999
