Only bad writers treat a kissing scene as just the physical action between two sets of lips. A true kissing dexcribe is the tension between two people before the kiss, the psychology during the kiss, and the reactions afterwards. Pay attention to psychology. A kissing scene isn’t just about the physical act of kissing. Sep 29, · Infectious mononucleosis, or "mono", is an infection usually caused by the Epstein-Barr virus. The virus spreads through saliva, which is why it's sometimes called "kissing disease." Mono occurs most often in teens and young adults.
However, you can get it at any age. Symptoms of mono include: Sometimes you may also have a swollen spleen. Glandular fever is the common term used to describe an acute viral infection called infectious mononucleosis. In the past, it was commonly known as kissing disease or mono. The virus that causes glandular fever is known as Epstein-Barr virus.

. If Chagas disease progresses to the long-lasting chronic definitiion, serious heart or digestive complications may occur. Mayo Clinic does not endorse companies or products. Principles of epidemiology, 2nd ed. Signs and symptoms of the chronic phase of Chagas disease may occur 10 to 20 years after initial infection, or they may never occur. Actions for this page
The acute phase of Chagas disease, which lasts for weeks or months, is often symptom-free.
When signs and symptoms do occur, they are usually mild and may include:. Signs and symptoms that develop during the acute phase usually go away on their own. In some cases, if the infection isn't treated, Chagas https://modernalternativemama.com/wp-content/category/where-am-i-right-now/are-lip-tint-long-lasting-makeup-brands.php will advance to the chronic phase. Signs and symptoms of the describe kissing disease definition human phase of Chagas disease may occur 10 to 20 years after initial infection, or they may never occur. In severe cases, Chagas disease signs and symptoms may include:. See your doctor if you live in or have traveled to an area where Chagas disease is widespread and you have signs and symptoms of the condition. Symptoms may include swelling at the infection site, fever, fatigue, body aches, rash and nausea.
The cause of Chagas disease is the parasite Trypanosoma cruzi, which is spread from an insect known as the triatomine bug, or "kissing bug. Triatomine bugs describe kissing disease definition human primarily in mud, thatch or adobe huts in Mexico, South America and Central America. They hide in crevices in the walls or roof during the day and come out at night — often feeding on sleeping humans. Infected bugs defecate after feeding, leaving behind parasites on the skin. The parasites can then enter your body through your eyes, mouth, a cut or scratch, or the wound from the bug's bite. Scratching or rubbing the bite site helps the parasites enter your body.
Once in your body, the parasites multiply and spread. It's rare for travelers to the at-risk areas in South America, Central America and Mexico to catch Chagas disease because travelers tend to stay in well-constructed buildings, such as hotels. Signs and symptoms such as a fever and sore throat usually lessen within a couple of weeks.
But fatigue, enlarged lymph nodes and a swollen spleen may last for a few weeks longer. The most common cause of mononucleosis is the Epstein-Barr virus, but other viruses also can cause similar symptoms. This virus is spread through saliva, and you may catch it from kissing or from sharing food or drinks. Although the symptoms of mononucleosis are uncomfortable, the infection resolves on its own without long-term effects. Most adults have been exposed to the Epstein-Barr virus and have built up antibodies. This means they're immune and won't get mononucleosis. The spleen is a small organ usually about the size of your fist.
But a number of conditions, including liver disease and some cancers, can cause your spleen to become enlarged. Mononucleosis may cause enlargement of the spleen. In extreme cases, your spleen may rupture, causing link, sudden pain in the left side of your upper abdomen. If such pain occurs, seek describe kissing disease definition human attention immediately — you may need surgery. The Epstein-Barr virus can cause much more serious illness in people who have impaired immune systems. Mononucleosis is spread through saliva. If you're infected, you can help prevent spreading the virus to others by not kissing them and by not sharing food, dishes, glasses and utensils until several days after your fever has improved — and even longer, if possible.
And remember to wash your hands regularly to prevent spread of the virus. The Epstein-Barr virus may persist in your saliva for months after the infection. No vaccine exists to prevent mononucleosis. Vectors such as mosquitoes, fleas, and ticks may carry an infectious agent through purely mechanical means or may support growth or changes in the agent. Examples of mechanical transmission describe kissing disease definition human flies carrying Shigella on their appendages and fleas carrying Yersinia pestisthe causative agent of plague, in their gut.
In contrast, in biologic transmission, the causative agent of malaria or guinea worm disease undergoes maturation in an intermediate host before it can be transmitted to humans Figure 1. The portal of entry refers to the manner in which a pathogen enters a susceptible host. The portal of entry must provide access to tissues in which the pathogen can multiply or a toxin can act. Often, infectious agents use describe kissing disease definition human same portal to enter a new host that they used to exit the source host. For example, influenza virus exits the respiratory tract of the source host and enters the respiratory tract of the new host. Other portals of entry include the skin hookwormmucous membranes syphilisand blood hepatitis B, human immunodeficiency virus. Figure 1. The final link in the chain of infection is a susceptible host.
For example, persons with sickle cell trait seem to be at least partially protected from a particular type of malaria. Specific immunity refers to protective antibodies that are directed against a describe kissing disease definition human agent. Such antibodies may develop in response to infection, vaccine, or toxoid toxin that has been deactivated but retains its capacity to stimulate production of toxin antibodies or may be acquired by transplacental transfer from mother to fetus or by injection of antitoxin or immune globulin. Nonspecific factors that defend against infection include the skin, mucous membranes, gastric acidity, cilia in the respiratory tract, the cough reflex, and nonspecific immune response. Factors that may increase susceptibility to infection by disrupting host defenses include malnutrition, alcoholism, and disease or therapy that impairs the nonspecific immune response.
Knowledge of the portals of exit and entry and modes of transmission provides a basis for determining appropriate control measures. In general, control describe kissing disease definition human are usually directed against the segment in the infection chain that is most susceptible to intervention, unless practical issues dictate otherwise. For some diseases, the most appropriate intervention may be directed at controlling or eliminating the agent at its source. A patient sick with a communicable disease may be treated with antibiotics to eliminate the infection. An asymptomatic but infected person may be treated both to clear the infection and to reduce the risk of transmission to others. In the community, soil may be decontaminated or covered to prevent escape of the agent.
Some interventions are directed at the mode of transmission. Interruption of direct transmission may be accomplished by isolation of someone with infection, or counseling persons to avoid the specific type of contact associated with transmission. Vehicleborne transmission may be interrupted by elimination or decontamination of the vehicle. To prevent fecal-oral transmission, efforts often focus on rearranging the environment to reduce the risk of contamination in the future and on changing behaviors, such as promoting handwashing. For airborne diseases, strategies may be directed at modifying ventilation or air pressure, and filtering or treating the air. To interrupt vectorborne transmission, measures may be directed toward controlling the vector population, such as spraying to reduce the mosquito population. Some strategies that protect portals of entry are simple and effective.
For example, bed nets are used to protect sleeping persons from being bitten by mosquitoes that may transmit malaria. Wearing of long pants and sleeves and use of insect repellent are recommended to reduce the risk of Lyme disease and West Nile virus infection, which are transmitted by the bite of ticks and mosquitoes, respectively. Vaccinations how do we learn to listen to development of specific antibodies that protect against infection.
COVID-19: Advice, updates and vaccine options
On the other hand, prophylactic use of antimalarial drugs, recommended for visitors to malaria-endemic areas, does not prevent exposure through mosquito bites, but does prevent infection from taking root. Finally, some interventions attempt to prevent a pathogen from encountering a susceptible host. The degree of herd immunity necessary to prevent or interrupt an outbreak varies by disease. In theory, herd immunity means that not everyone in a community needs to be resistant immune to prevent disease spread and occurrence of an outbreak. One problem is that, in highly immunized populations, the relatively few susceptible persons are often clustered in subgroups defined by socioeconomic or cultural factors. If the pathogen is introduced into one of these subgroups, an outbreak may occur. Information about dengue fever is provided on the following pages.
After studying this information, outline the chain of infection by identifying the reservoir sportal s of exit, mode s of transmission, portal s of entry, and factors in host susceptibility. Check your answer. Dengue is an acute infectious disease that comes in two forms: dengue and dengue hemorrhagic fever. The principal symptoms of dengue are high fever, severe headache, backache, joint pains, nausea and vomiting, eye pain, and rash. Generally, younger children have a milder illness than older children and adults. Dengue hemorrhagic fever is a more severe form of dengue. It is characterized by a fever that lasts from 2 to 7 days, with general signs and symptoms that could occur with many other illnesses e. This stage is describe kissing disease definition human by hemorrhagic manifestations, tendency to bruise easily or other types of skin hemorrhages, bleeding nose or gums, and possibly internal bleeding.
This may lead to failure of the circulatory system and shock, followed by death, if circulatory failure is not corrected. Diagnosis of dengue infection requires laboratory confirmation, either by isolating the virus from serum within 5 days after onset of symptoms, or by detecting convalescent-phase specific antibodies obtained at least 6 days after onset of symptoms. There is no specific medication for treatment of describe kissing disease definition human dengue infection. Persons who think they have dengue should use analgesics pain relievers with acetaminophen and avoid those containing aspirin.
They should also rest, click the following article plenty of fluids, and consult a physician. Persons with dengue hemorrhagic fever can be effectively treated by fluid replacement therapy if an early clinical diagnosis is made, but hospitalization is often required. Dengue is endemic in many tropical countries in Asia and Latin America, most countries in Africa, and much of the Caribbean, including Puerto Rico. Cases have occurred sporadically in Texas. Epidemics occur periodically. Globally, an estimated 50 to million cases of dengue and several hundred thousand cases of dengue hemorrhagic fever occur each year, depending on epidemic activity.
