Epidemics In India
An epidemic (from Greek ἐπί ''epi'' "upon or above" and δῆμος ''demos'' "people") is the rapid spread of disease to a large number of hosts in a given population within a short period of time. For example, in meningococcal infections, an attack rate in excess of 15 cases per 100,000 people for two consecutive weeks is considered an epidemic. Epidemics of infectious disease are generally caused by several factors including a change in the ecology of the host population (e.g., increased stress or increase in the density of a vector species), a genetic change in the pathogen reservoir or the introduction of an emerging pathogen to a host population (by movement of pathogen or host). Generally, an epidemic occurs when host immunity to either an established pathogen or newly emerging novel pathogen is suddenly reduced below that found in the endemic equilibrium and the transmission threshold is exceeded. An epidemic may be restricted to one location; however, if it spreads ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Disease Vector
In epidemiology, a disease vector is any living agent that carries and transmits an infectious pathogen such as a parasite or microbe, to another living organism. Agents regarded as vectors are mostly blood-sucking ( hematophagous) arthropods such as mosquitoes. The first major discovery of a disease vector came from Ronald Ross in 1897, who discovered the malaria pathogen when he dissected the stomach tissue of a mosquito. Arthropods Arthropods form a major group of pathogen vectors with mosquitoes, flies, sand flies, lice, fleas, ticks, and mites transmitting a huge number of pathogens. Many such vectors are haematophagous, which feed on blood at some or all stages of their lives. When the insects and ticks feed on blood, the pathogen enters the blood stream of the host. This can happen in different ways. The '' Anopheles'' mosquito, a vector for malaria, filariasis, and various arthropod-borne-viruses ( arboviruses), inserts its delicate mouthpart under the skin and feeds ...

Plague Of Athens
The Plague of Athens (, ) was an epidemic that devastated the city-state of Athens in ancient Greece during the second year (430 BC) of the Peloponnesian War when an Athenian victory still seemed within reach. The plague killed an estimated 75,000 to 100,000 people, around 25% of the population, and is believed to have entered Athens through Piraeus, the city's port and sole source of food and supplies. Thucydides, an Athenian survivor, wrote that much of the eastern Mediterranean also saw an outbreak of the disease, albeit with less impact.Thucydides, ''History of the Peloponnesian War'' 2.49 The war, along with the plague, had lasting effects on Athenian society. Short-term, there was civil disorder, and violations of usual funerary practices. Thucydides describes a decrease in traditional religious practices and increase in superstitious explanations. He estimates that it took 15 years for the Athenian population to recover. Long-term, the high death toll drastically redistri ...

Thucydides
Thucydides ( ; ; BC) was an Classical Athens, Athenian historian and general. His ''History of the Peloponnesian War'' recounts Peloponnesian War, the fifth-century BC war between Sparta and Athens until the year 411 BC. Thucydides has been dubbed the father of "scientific history" by those who accept his claims to have applied strict standards of impartiality and evidence-gathering and analysis of cause and effect, without reference to intervention by the Ancient Greek religion, gods, as outlined in his introduction to his work. Thucydides has been called the father of the school of political realism, which views the political behavior of individuals and the subsequent outcomes of relations between states as ultimately mediated by, and constructed upon, fear and self-interest. His text is still studied at universities and military colleges worldwide. The Melian dialogue is regarded as a seminal text of international relations theory, while his version of Pericles's Funeral O ...

Hippocrates
Hippocrates of Kos (; ; ), also known as Hippocrates II, was a Greek physician and philosopher of the Classical Greece, classical period who is considered one of the most outstanding figures in the history of medicine. He is traditionally referred to as the "Father of Medicine" in recognition of his lasting contributions to the field, such as the use of prognosis and clinical observation, the systematic categorization of diseases, and the (however misguided) formulation of Humorism, humoral theory. His studies set out the basic ideas of modern-day specialties, including surgery, urology, neurology, acute medicine and Orthopedic surgery, orthopedics. The Hippocratic school of medicine revolutionized ancient Greek medicine, establishing it as a discipline distinct from other fields with which it had traditionally been associated (theurgy and philosophy), thus establishing medicine as a profession. However, the achievements of the writers of the Hippocratic Corpus, the practitioners ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odyssey
The ''Odyssey'' (; ) is one of two major epics of ancient Greek literature attributed to Homer. It is one of the oldest surviving works of literature and remains popular with modern audiences. Like the ''Iliad'', the ''Odyssey'' is divided into 24 books. It follows the heroic king of Ithaca, Odysseus, also known by the Latin variant Ulysses, and his homecoming journey after the ten-year long Trojan War. His journey from Troy to Ithaca lasts an additional ten years, during which time he encounters many perils and all of his crewmates are killed. In Odysseus's long absence, he is presumed dead, leaving his wife Penelope and son Telemachus to contend with a group of unruly suitors competing for Penelope's hand in marriage. The ''Odyssey'' was first written down in Homeric Greek around the 8th or 7th century BC; by the mid-6th century BC, it had become part of the Greek literary canon. In antiquity, Homer's authorship was taken as true, but contemporary sch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homer
Homer (; , ; possibly born ) was an Ancient Greece, Ancient Greek poet who is credited as the author of the ''Iliad'' and the ''Odyssey'', two epic poems that are foundational works of ancient Greek literature. Despite doubts about his authorship, Homer is considered one of the most revered and influential authors in history. The ''Iliad'' centers on a quarrel between King Agamemnon and the warrior Achilles during the last year of the Trojan War. The ''Odyssey'' chronicles the ten-year journey of Odysseus, king of Homer's Ithaca, Ithaca, back to his home after the fall of Troy. The epics depict man's struggle, the ''Odyssey'' especially so, as Odysseus perseveres through the punishment of the gods. The poems are in Homeric Greek, also known as Epic Greek, a literary language that shows a mixture of features of the Ionic Greek, Ionic and Aeolic Greek, Aeolic dialects from different centuries; the predominant influence is Eastern Ionic. Most researchers believe that the poems w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obesity Epidemic
Obesity has been observed throughout human history. Many early depictions of the human form in art and sculpture appear obese. However, it was not until the 20th century that obesity became common — so much so that, in 1997, the World Health Organization (WHO) formally recognized obesity as a global epidemic and estimated that the worldwide prevalence of obesity has nearly tripled since 1975. Obesity is defined as having a body mass index (BMI) greater than or equal to 30 kg/m2, and in June 2013 the American Medical Association classified it as a disease. In countries of the Organisation for Economic Co-operation and Development (OECD), one child out of five is overweight or obese. Once considered a problem only of high-income countries, obesity rates are rising worldwide. In 2014, the mean BMI in 128 countries was above the threshold for overweight. Globally, there are now more people who are obese than who are underweight, a trend observed in every region over the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HIV/AIDS
The HIV, human immunodeficiency virus (HIV) is a retrovirus that attacks the immune system. Without treatment, it can lead to a spectrum of conditions including acquired immunodeficiency syndrome (AIDS). It is a Preventive healthcare, preventable disease. It can be managed with treatment and become a manageable chronic health condition. While there is no cure or vaccine for HIV, Management of HIV/AIDS, antiretroviral treatment can slow the course of the disease, and if used before significant disease progression, can extend the life expectancy of someone living with HIV to a nearly standard level. An HIV-positive person on treatment can expect to live a normal life, and die with the virus, not of it. Effective #Treatment, treatment for HIV-positive people (people living with HIV) involves a life-long regimen of medicine to suppress the virus, making the viral load undetectable. Treatment is recommended as soon as the diagnosis is made. An HIV-positive person who has an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexually Transmitted Infection
A sexually transmitted infection (STI), also referred to as a sexually transmitted disease (STD) and the older term venereal disease (VD), is an infection that is Transmission (medicine), spread by Human sexual activity, sexual activity, especially Sexual intercourse, vaginal intercourse, anal sex, oral sex, or sometimes Non-penetrative sex#Manual sex, manual sex. STIs often do not initially cause symptoms, which results in a risk of transmitting them to others. The term ''sexually transmitted infection'' is generally preferred over ''sexually transmitted disease'' or ''venereal disease'', as it includes cases with no Signs and symptoms#Symptomatic, symptomatic disease. Symptoms and signs of STIs may include vaginal discharge, penile discharge, genital ulcers, ulcers on or around the genitals, and pelvic pain. Some STIs can cause infertility. Bacterial STIs include Chlamydia infection, chlamydia, gonorrhea, and syphilis. Viral STIs include genital warts, genital herpes, and ...
