Calabazo Virus
Calabazo virus is an enveloped, single-stranded, negative-sense RNA hantavirus species of the order ''Bunyavirales''. It is a novel New World microtine rodent-borne hantavirus discovered in Central America on the Azuero Peninsula of Panama in early 2000. Human infection with Calabazo virus results in respiratory illness similar to Hantavirus pulmonary syndrome but it is not severe or fatal and rarely requires hospitalization. Reservoir Calabazo virus was identified in the cane mouse (Zygodontomys brevicauda). Transmission Calabazo virus has not been shown to transfer from person-to-person. Transmission by aerosolized rodent excreta still remains the only known way the hantaviruses are transmitted to humans. In general, droplet and/or fomite transfer has not been shown in these viruses in either the hemorrhagic or pulmonary forms.

Hantavirus
''Orthohantavirus'' is a genus of viruses that includes all hantaviruses (family ''Hantaviridae'') that cause disease in humans. Orthohantaviruses, hereafter referred to as hantaviruses, are naturally found primarily in rodents. In general, each hantavirus is carried by one rodent species and each rodent that carries a hantavirus carries one hantavirus species. Hantaviruses in their natural reservoirs usually cause an asymptomatic, persistent infection. In humans, however, hantaviruses cause two diseases: hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). HFRS is mainly caused by hantaviruses in Africa, Asia, and Europe, called Old World hantaviruses, and HPS is usually caused by hantaviruses in the Americas, called New World hantaviruses. Hantaviruses are transmitted mainly through aerosols and droplets that contain rodent excretions, as well as through contaminated food, bites, and scratches. Environmental factors such as rainfall, temperature, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bunyavirales
''Bunyaviricetes'' is a class of segmented negative-strand RNA viruses with mainly tripartite genomes. Member viruses infect arthropods, plants, protozoans, and vertebrates. The name ''Bunyaviricetes'' derives from Bunyamwera, where the virus Bunyamwera virus was first discovered. Bunyaviruses belong to the fifth group of the Baltimore classification, Baltimore classification system, which includes viruses with a Sense (molecular biology), negative-sense, single-stranded RNA genome. They have an Viral envelope, enveloped, spherical virion. Though generally found in arthropods or rodents, certain viruses in this class occasionally infect humans. Some of them also infect plants. In addition, there is a group of bunyaviruses whose replication is restricted to arthropods and is known as insect-specific bunyaviruses. A majority of bunyaviruses are vector-borne. With the exception of Hantaviruses and Arenaviruses, all viruses in the ''Bunyaviricetes'' class are Arbovirus, transmitted ...

Central America
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes, which has resulted in death, injury, and property damage. Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain ...

Panama
Panama, officially the Republic of Panama, is a country in Latin America at the southern end of Central America, bordering South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half of the country's over million inhabitants. Before the arrival of Spanish Empire, Spanish colonists in the 16th century, Panama was inhabited by a number of different Indigenous peoples of Panama, indigenous tribes. It Independence Act of Panama, broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Viceroyalty of New Granada, Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Choclo Virus
Choclo virus (CHOV) is a single-stranded, negative-sense RNA zoonotic New World hantavirus. It was first isolated in 1999 in western Panama. The finding marked the first time Hantavirus pulmonary syndrome (HPS) was found in Central America. During this outbreak, a high seroprevalence was found among the general population, suggesting that this virus has an extremely low pathogenicity and causes sub-clinical to mild symptoms. This was confirmed in a study that infected hamsters with CHOV. All of the hamsters tested positive for CHOV, but none exhibited any symptoms. Discovery The virus was first isolated in 2000 from the spleen of a northern pygmy rice rat captured in Las Tablas, Los Santos in the Los Santos Province in western Panama and is named after the El Choclo cantina near the city. Transmission Choclo virus has not been shown to transfer from person-to-person. Transmission by aerosolized rodent excreta still remains the only known way the virus is transmitted to hum ...

Hantavirus Pulmonary Syndrome
Hantavirus pulmonary syndrome (HPS), also called hantavirus cardiopulmonary syndrome (HCPS), is a severe respiratory disease caused by hantaviruses. The main features of illness are microvascular leakage and acute respiratory distress syndrome. Symptoms occur anywhere from one to eight weeks after exposure to the virus and come in three distinct phases. First, there is an early phase with flu-like symptoms such as fever, muscle aches, headache, and shortness of breath, as well as low platelet count. Second, there is cardiopulmonary phase during which people experience elevated or irregular heart rate, cardiogenic shock, and pulmonary capillary leakage, which can lead to respiratory failure, low blood pressure, and buildup of fluid in the lungs and chest cavity. The final phase is recovery, which typically takes months, but difficulties with breathing can persist for up to two years. The disease has a case fatality rate of 30 to 60 percent. Death usually occurs suddenly during the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1993 Four Corners Hantavirus Outbreak
The 1993 Four Corners hantavirus outbreak was an outbreak of Orthohantavirus, hantavirus disease in the United States in the Four Corners region of Arizona, Colorado, and New Mexico. Hantaviruses that cause disease in humans are native to rodents and, before the outbreak, were mainly found in Asia and Europe. Previously, however, they were only known to cause hemorrhagic fever with renal syndrome. The outbreak in the Four Corners region led to the discovery of hantaviruses from the Western Hemisphere that could cause disease and revealed the existence of a second disease caused by hantaviruses: hantavirus pulmonary syndrome (HPS). Thirty-three HPS cases were confirmed in the Four Corners states in 1993, Nationwide, 48 cases were confirmed, 27 of which (56%) resulted in death. The earliest confirmed cases of HPS in 1993 occurred in March, but the outbreak was not discovered until May when a young Navajo couple died within days of each other due to sudden respiratory failure.
