Hyponatremia Overview Hyponatremia is a condition that happens when the level of sodium in the blood is lower than the typical range. Sodium is an electrolyte, and it helps regulate the amount of water that's in and around your cells. In hyponatremia, one or more factors cause the sodium in the body to be diluted. These factors can range from an underlying medical condition to drinking too much water. When this happens, the body's water levels rise, and cells begin to swell. This swelling can cause many health problems, from mild to life-threatening. Hyponatremia treatment is aimed at resolving the underlying condition. Depending on the cause of hyponatremia, you may simply need to cut back on how much you drink. In other cases of hyponatremia, you may need intravenous electrolyte solutions and medications. What are the types of hyponatremia? Types of hyponatremia include: Euvolemic hyponatremia/dilutional hyponatremia. This is when the amount of sodium in your body stays the ...
Crimean-Congo haemorrhagic fever Overview Crimean-Congo haemorrhagic fever (CCHF) is a widespread disease caused by a tick-borne virus (Nairovirus) of the Bunyaviridae family. The CCHF virus causes severe viral haemorrhagic fever outbreaks, with a case fatality rate of 10–40%. CCHF is endemic in Africa, the Balkans, the Middle East and Asian countries south of the 50th parallel north – the geographical limit of the principal tick vector. The Crimean-Congo haemorrhagic fever virus in animals and ticks The hosts of the CCHF virus include a wide range of wild and domestic animals such as cattle, sheep and goats. Many birds are resistant to infection, but ostriches are susceptible and may show a high prevalence of infection in endemic areas, where they have been at the origin of human cases. For example, a former outbreak occurred at an ostrich abattoir in South Africa. There is no apparent disease in these animals. Animals become infected by the bite of infected ticks and the virus remain...
