HIV, like many other STD's is transmitted through unprotected sexual intercourse. However, it can also be transmitted by infected "blood transfusions", an infected mother to fetus, and sharing infected needles as well as breast milk (2009, NIAID). The reason it is really unlikely that a person should contract this virus by skin contact, is because the way HIV invades a person's system (2009, NIAID). The virus itself has special markers on its plasma membrane called "CD Markers" that locate specific cells within a person's body that target specific cells such as helper-T Cells and Microphages (2012, Phelan). The HIV virus cannot invade cells that it cannot latch on to, so a handshake with a person who has HIV will not transfer the disease because skin cells do not have the appropriate receptors that the virus can attack. When the HIV cells find the specific cell it targets, they attach themselves to its surface and then releases its DNA proteins into the cell. The virus's DNA then take over the host cell's DNA and commands it to create copies of the HIV virus. The cell produces viral RNA which creates viral proteins that migrate to the cell edge and form an undeveloped HIV virus which then is expelled from the cell and matures into a new copy of the HIV virus.
In some rare cases, some people possess a gene that blocks and prevents HIV. According to an article in the Wall Street Journal, some people are born with a rare mutated gene that inactivates the "CCr5" gene, which is crucial for the HIV virus to infiltrate immune system cells. Without this gene activated, the HIV cannot infect the person. Some researchers believe that this rare gene came about as a mutation in Europe during the era in which of bubonic plague came about (2...

It is crucial to understand that, unlike most transmissible diseases, AIDS/HIV is not transmitted through sneezing, coughing, eating or drinking from common utensils, or even being around an infected person. Casual contact with AIDS/HIV infected persons does not place others at risk. HIV/AIDS can be passed through unprotected sex with an infected person, sharing contaminated needles, from infected mother to baby during pregnancy, birth or breastfeeding, and through direct exposure to infected blood or blood
His life began three weeks earlier than I was than he was expected. This was a result of me having high blood pressure, premature dilation of the cervix, and taking a late maternity leave. These problems led me to being on bed rest for the next two months after his birth. At the last prenatal check, Ivan was showing some signs of distress and the doctor decided to induce my labor. Ivan’s early arrival came on the 20th of August at 5:52 p.m. Ivan’s weight was around 5 pounds and had an Apgar score of 6. An Apgar score is the standardized measurement system that looks for a variety of indications of good health in newborns (Feldman, 2014). Some factors that are analyzed are the appearance, pulse, reflexes, activity, and respiration of the newborn to determine their good health (Feldman, 2014). Using this scale, nurses
Different people define success in many different ways. What is considered success by one person may be viewed as failure by another person. Randy Shilts, a homosexual newspaper reporter / author, attempts to make fundamental changes in America’s opinion on AIDS. In Randy Shilts’s essay, "Talking AIDS to Death," he speaks of his experiences as an "AIDS celebrity." At the core of Shilts’s essay is the statement, "Never before have I succeeded so well; never before have I failed so miserably"(221). Shilts can see his accomplishments from two points of view- as a success and as a failure. Despite instant fame, Shilts is not satisfied with the effects his writings has on the general public. Shilts’s "success" and reasons for failure can both be considered when one decides whether or not his efforts were performed in vain.
A significant research investment has been made in helping to reduce the burden of HIV-1 infection worldwide. Antivirals help delay the onset of AIDS. Vaccine research has achieved some minor victories. Animal models allow more thorough and representative study of HIV-1. While HIV/AIDS still remains a major concern for the global community, continued research will doubtless bring further advances, helping to prevent infections before they occur and to provide better outcomes for those already infected with HIV-1. Fortunately, the battle with HIV/AIDS—though far from being over—is going better than it ever has before.
According to Lucile Packard Children’s Hospital, “In the United States, nearly thirteen percent of babies are born preterm, and many of these babies also have a low birth weight.” The baby may be put into the NICU for varies reasons. However, the most common reason that a child is put into the NICU is because he or she is premature. Premature means the baby was born before the 36 weeks. It is never good for a baby to be born early, as this could mean that the baby is not fully developed. There are other factors as to why a child may need to be put into the NICU after birth. For instance, birth defects can be the cause of why a baby is put into the NICU. A baby may be born with an infection such as herpes or chlamydia which can damage the newborns immune system at such a young age. Low blood sugar or hypoglycemia can also cause an infant to be put into the NICU. Some maternal factors of why a baby may be put into the NICU is if the mother is “younger than 16 or older than 40.” If the parent may be an alcoholic or expose the baby to drugs, this can put the child into NICU care. If the parent has an STD or sexual transmitted disease, the baby is most likely going to have to be put into the intensive care unit. “Twins, triplets, and other multiples are often admitted into the NICU, as they tend to be born earlier and s...
Acquired Immune Deficiency Syndrome (AIDS) was first recognized as a new disease in 1981 when increasing numbers of young homosexual men succumbed to unusual opportunistic infections and rare malignancies (Gallant49).During this time, many people were contacting this disease because it was not discovered yet and people did not have knowledge about it.Scientists believe HIV came from a particular kind of chimpanzee in Western Africa. Humans contracted this disease when they hunted and ate infected animals. A first clue came in 1986 when a morphologically similar but antigenically distinct virus was found to cause AIDS in patients in western Africa (Goosby24). During this time, scientists had more evidence to support their claim about this disease. Once discovered this disease was identified as a cause of what has since become one of the most devastating infectious diseases to have emerged in recent history (Goosby101). This disease was deadly because it was similar to the Black Death, it was killing majority of the population. Since its first identification almost three decades ago, the pandemic form of HIV-1 has infected at least 60 million people and caused more than 25 million deaths ...

Human Immunodeficiency Virus (HIV) was once considered a taboo disease that made its appearance in the United States around the late 1970s. Little was known about the virus and it was originally thought to just be found in the gay male community. As more and more research has been done people now understand the virus and realize that it affects men and women as well as all races, ages, and sexual orientation. It is believed that HIV is a mutated form of the Simian Immunodeficiency Virus (SIV) that is found in chimpanzees. It most likely moved to the human population from people hunting monkeys, coming in contact with their blood, and eating their meat (The Origin of HIV/AIDS, 2014).

HIV is a battle that has existed for a long time and is still an uphill battle for those affected. This sickness has not only hurt the people but it has grown to affect the economy and politics of numerous countries and regions like America and South Africa. Therefore, the stance on the resilience has grown over the past forty years. It has existed and grown and has come to be one of the biggest social issues in the world. It has become so intertwined with society that it has had lasting affects on all divisions of the world and those divisions are economic divisions, political division, and social divisions within Africa, America, and Asia.
HIV and AIDS have affected millions of people throughout the world. Since 1981, there have been 25 million deaths due to AIDS involving men, women, and children. Presently there are 40 million people living with HIV and AIDS around the world and two million die each year from AIDS related illnesses. The Center for Disease Control estimates that one-third of the one million Americans living with HIV are not aware that they have it. The earliest known case of HIV was in 1959. It was discovered in a blood sample from a man in Kinshasa, Democratic Republic of the Congo. Looking further into the genetics of this blood sample researchers suggested that it had originated from a virus going back to the late 1940’s or early 1950’s. In 1999, researchers had discovered that HIV is derived from chimpanzees native to west equatorial Africa. This epidemic is spreading throughout countries and infecting 14 thousand victims every day. Learning about HIV includes knowing how to contract the virus, understanding most of the people it affects, how to prevent the spread of it, and knowing what treatments are available.
Acquired Immunodeficiency Syndrome (AIDS) first came to light in 1981. There has been a long and arduous global effort on the prevention of HIV/AIDS. HIV is a virus that is spread through body fluids that affect the specific T-cells of the immune system. Without treatment HIV infection leads to AIDS and there is no cure for AIDS. HIV infection can be controlled and the importance of primary pre...
In 1981, a new fatal, infectious disease was diagnosed--AIDS (Acquired Immuno-Deficiency Syndrome). It began in major cities, such as New York, Los Angeles, Miami, and San Francisco. People, mostly homosexual men and intravenous drug users, were dying from very rare lung infections or from a cancer known as Kaposi’s sarcoma. They have not seen people getting these diseases in numerous years. Soon, it also affected hemophiliacs, blood recipients, prostitutes and their customers, and babies born from AIDS-infected women. AIDS was soon recognized as a worldwide health emergency, and as a fatal disease with no known cure, that quickly became an epidemic. When high-profile victims began to contract the virus, such as basketball star Magic Johnson, the feeling spread quickly that anyone, not just particular groups of people, could be at risk. AIDS impairs the human body’s immune system and leaves the victim susceptible to various infections. With new research, scientists think that the disease was first contracted through a certain type of green monkey in Africa, then somehow mutated into a virus that a human could get. AIDS is a complicated illness that may involve several phases. It is caused by a virus that can be passed from person to person. This virus is called HIV, or Human Immuno-deficiency Virus. In order for HIV to become full-blown AIDS, your T-cell count (number of a special type of white-blood cells that fight off diseases) has to drop below 200, or you have to get one of the symptoms of an AIDS-induced infection.
The emergence of HIV/AIDS is viewed globally as one of the most serious health and developmental challenges our society faces today. Being a lentivirus, HIV slowly replicates over time, attacking and wearing down the human immune system subsequently leading to AIDS (Acquired Immunodeficiency Syndrome) at which point the affected individual is exposed to life threatening illnesses and eventual death. Despite the fact that a few instances of this disease have been accounted for in all parts of the world, a high rate of the aforementioned living with HIV are situated in either low or medium wage procuring nations. The Sub-Saharan region Africa is recognized as the geographic region most afflicted by the pandemic. In previous years, people living with HIV or at risk of getting infected did not have enough access to prevention, care and treatment neither were they properly sensitized about the disease. These days, awareness and accessibility to all the mentioned (preventive methods, care etc.) has risen dramatically due to several global responses to the epidemic. An estimated half of newly infected people are among those under age 25(The Global HIV/AIDS Epidemic). It hits hard as it has no visible symptoms and can go a long time without being diagnosed until one is tested or before it is too late to manage.
