This is a study of diseases in humans and animals to know about how, when and why they occurred. Epidemiologist will determine what factors are associated with diseases and the factors to protect people and animals from diseases. They are also responsible to give reports to the health centres.
In this data is collected as per the disease occurring or spreading in many areas, which lead to control the flow of disease such as Swine Flu,Dengue etc.. Also it is very important to manage and examine the rates of disease. Management is responsible to handle old records and new records to ensure that the report is perfectly suitable to find the cause of disease.
<p>In this researcher are responsible to prepare a curable report on disease. As It is common that Researcher are the key persons to collect all the data regarding the disease and providing info to the labs. 1.Research team will define key terms. 2.Give important topics on health. 3.Help in describing the public health.</p>
Scientists think that people who are infected with the virus for example such as Ebola, Corona etc.. through the contact of infected animals.Which leads to death and this virus spread person to person very quick in large number. The virus spreads through direct contact (such as through broken skin or mucous membranes in the eyes, nose, or mouth) or indirect contact.
Pandemic outbreak is a disease which spreads all over the world and killed large number of peoples. It’s a huge disease or virus spreads very quick.
Epidemic is a disease which include yellow fever, bubonic plague, influenza, smallpox, chickenpox, typhus, and syndemic infection of hepatitis B and hepatitis D. These diseases spreads from person to person if anyone get contact with this and should take very safe precautions.
Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They're normally harmless or even helpful. But under certain conditions, some organisms may cause disease.
A disease caused by consuming contaminated food or drink is known as “Foodborne Diseases”. These diseases are caused by bacteria, viruses and parasites which are present in food that contaminates. However, symptoms may differ among the different types of foodborne diseases.
The International Health Regulations are binding instrument of international law that aims to a assist countries to work together to save lives and livelihoods endangered by the international spread of diseases and other health risks and b avoid unnecessary interference with international trade and travel.
Travellers may get sudden and significant changes in altitude, humidity, microbes, and temperature, which can result in ill-health. International travel can pose various risks to health, depending on the characteristics of both the traveler and the travel. Serious health risks may arise in areas where accommodation is of poor quality, hygiene and sanitation are inadequate, medical services are not well developed and clean water is unavailable. Peoples who are planning to travel country to country should have forward planning for their health.
Most common tropical diseases are trypanosomiasis, chagas disease, schistosomiasis, leishmaniasis, lymphatic filariasis, onchocerciasis. Tropical diseases are infectious diseases that either occur in tropical and subtropical regions (which is rare) or, more commonly, are more difficult to prevent or control. Bacteria and viruses are the main reason to cause tropical diseases and it is common in US. In addition, many diseases are spread by contaminated water and food sources, since clean water and sanitary conditions are often a luxury in developing countries.
Influenza, or flu, is a virus that attacks the respiratory system. The flu virus is highly contagious: When an infected person coughs, sneezes or talks, respiratory droplets are generated and transmitted into the air, and can then can be inhaled by anyone nearby. Additionally, a person who touches something with the virus on it and then touches his or her mouth, eyes or nose can become infected.
A zoonotic disease is a disease spread between animals and people. Zoonotic diseases can be caused by viruses, bacteria, parasites, and fungi. Some of these diseases are very common.
Coronaviruses are a large family of viruses that can cause illness ranging from the common cold to more severe diseases Novel coronavirus is first occurred in Wuhan, China at the end of 2019. Till January 24, 2020, 830 cases had been spread in nine countries such as China, Thailand, Japan, South Korea, Singapore, Vietnam, Taiwan, Nepal, and the United States. Twenty-six fatalities occurred, mainly in patients who had serious underlying illness.
Zika virus is caused and transmitted by Mosquitoes, which bite during the day. Symptoms are generally mild and include fever, rash, conjunctivitis, muscle and joint pain, malaise or headache. Most people with Zika virus infection do not develop symptoms. Also very dangerous if not treated well. There is no treatment available for Zika virus infection or its associated diseases.
Ebola virus disease is formerly known as Ebola haemorrhagic fever, which is very dangerous virus and rare. Ebola Virus Disease is a rare and deadly disease in people and nonhuman primates. The viruses that cause EVD are located mainly in sub-Saharan Africa. People can get EVD through direct contact with an infected animal (bat or nonhuman primate) or a sick or dead person infected with Ebola virus.
<p>HIV also known as human immunodeficiency virus that damages the cells in our immune system and breaks the ecosystem within our body by debilitating the ability to fight common infections and diseases. Most of the people affected with this virus portray symptoms like a short flu-like illness 2 to 6 weeks after the infestation, which lasts for a period of 2 weeks. After these symptoms begin to heal, this virus may not cause any further symptoms for a long period of time, although the virus continues to damage the immune system from within. HIV is found in the body fluids of an infected person. </p>
Although swine flu not only affects humans, there was a global outbreak (pandemic) in 2009–2010, the first flu pandemic in more than 40 years. It was caused by a then-new flu virus known as H1N1, a type. A influenza virus that's a combination of swine, avian (bird), and human genes that mixed together in pigs and spread to humans.
Measles is a highly contagious illness caused by a virus that replicates in the nose and throat of an infected child or adult. Then, when someone with measles coughs, sneezes or talks, infected droplets spray into the air, where other people can inhale them.
Middle East respiratory syndrome (MERS) is a viral respiratory illness caused by a coronavirus (Middle East respiratory syndrome coronavirus, or MERS‐CoV) that was first identified in Saudi Arabia in 2012. Coronaviruses are a large family of viruses that can cause diseases in humans, ranging from the common cold to Severe Acute Respiratory Syndrome (SARS).
Arbovirus is an informal name used to refer to any viruses that are transmitted by arthropod vectors. The word arbovirus is an acronym (arthropod-borne virus).The word tibovirus (tick-borne virus) is sometimes used to more specifically describe viruses transmitted by ticks, a superorder within the arthropods. Arboviruses can affect both animals (including humans) and plants. In humans, symptoms of arbovirus infection generally occur 3–15 days after exposure to the virus and last three or four days.
