Corona Virus

BackgroundThe World Health Organization (WHO) has been on alert since the 31st December 2019, following an outbreak of a new strain of coronavirus in Wuhan City, China late last month.Coronavirus is a family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS), pneumonia and bronchitis.This new strain infecting humans was named "2019-nCoV". Little is known about this strain of coronavirus, although human-to-human transmission has been confirmed.Coronaviruses are common amongst animals worldwide, but only a handful of them are known to affect humans.Though the spread of the virus seems to have been contained within a few cities circling Wuhan, there have been a few cases reported outside of China.Chinese officials have effectively sealed off the region with travel bans to and from the affected areas and airports across the world have also stepped up screening passengers coming from that region.What are the symptoms? According to WHO, signs of infection ranges from respiratory symptoms such as fever, cough and breathing difficulties; it also includes impaired liver and kidney function. In more severe cases, it can lead to Pneumonia, SARS, kidney failure and even death. The incubation period of the 2019-nCoV strain is yet to be determined. How is it transmitted? As with other coronaviruses, 2019-nCoV can be transmitted in the following ways: l Through air by coughing sneezing l Close contact such us touching and shaking hands with infected person l Contact with contaminated objects then touching the mouth, eyes or nose.How is it treated?There are no specific treatments for all coronavirus infections and most people will recover on their own, available measures involves rest and medication to relieve symptoms.You are however advised to drink a lot of fluids and have enough rest should you worry about your symptoms.There is no vaccine for the new coronavirus (2019-nCoV).

Geography of Landslides. Mitigation and Resilience.

A landslide is a geological event in which a mass of rock, earth, or debris moves down a slope under the force of gravity. Landslides can range in size from small to large and can be triggered by natural events such as heavy rainfall, earthquakes, or volcanic activity, or by human activities such as construction or mining. The geography of landslides is affected by a variety of factors that can increase the likelihood of landslides occurring in a particular area. These factors include slope angle and steepness, the type of soil and rock present, the climate and weather patterns of the region, the presence or absence of vegetation, and human activities such as construction, mining, and deforestation. Areas with steep slopes are more prone to landslides because gravity has a stronger effect on loose soil and rock, making it more likely to move downhill. Similarly, areas with loose, sandy soil or weak, fractured rock are more prone to landslides because they are less stable and more easil...

Geography of Flood. Types. Charector.

The geography of floods refers to the characteristics and patterns of floods in different geographic regions. Floods can occur in various landscapes, such as mountains, plains, coastal areas, and urban environments. The geography of a region plays a significant role in determining the frequency, magnitude, and impacts of floods. Some of the factors that influence the geography of floods include: Topography: The shape and elevation of the land can affect the flow and accumulation of water during a flood. For example, flat terrain can lead to slow-moving and widespread flooding, while steep slopes can result in flash floods and landslides. Climate: Regions with high rainfall or snowmelt can experience more frequent and intense floods, while dry regions may experience flash floods due to sudden, heavy rainfall. Hydrology: The characteristics of a river basin, such as its size, shape, and water flow, can influence the severity of a flood. For example, large river basins with extensive floo...

Flood prone regions India

Floods are natural disasters characterized by the overflow of water onto normally dry land. Various factors contribute to floods, including intense rainfall, rapid snowmelt, storm surges from coastal storms, and the failure of dams or levees. The geographical explanation involves understanding the key components of flood-prone regions: 1. Proximity to Water Bodies: Flood-prone regions are often situated near rivers, lakes, or coastal areas. These locations are more susceptible to flooding as they are in close proximity to large water sources that can overflow during heavy precipitation or storms. 2. Topography: Low-lying areas with gentle slopes are prone to flooding. Water naturally flows to lower elevations, and flat terrains allow water to accumulate easily. Valleys and floodplains are common flood-prone areas due to their topographical characteristics. 3. Rainfall Patterns: Regions with high and concentrated rainfall are more likely to experience flooding. Intense and prol...

Landslides. TYPES OF LANDSLIDES The term "landslide" describes a wide variety of processes that result in the downward and outward movement of slope-forming materials including rock, soil, artificial fill, or a combination of these. The materials may move by falling, toppling, sliding, spreading, or flowing. The animated GIF shows a graphic illustration of different types of landslides, with the commonly accepted terminology describing their features. The various types of landslides can be differentiated by the kinds of material involved and the mode of movement.
