CAPE TOWN Sacramento Kings Women's Jersey , Oct. 31 (Xinhua) -- South African health authorities on Tuesday issued a malaria alert after high numbers of malaria cases were reported.


Everyone is at risk of contracting malaria in malarious areas but children under five years of age, pregnant women, people with compromised immune systems, travellers from non-endemic areas and immigrant workers are at higher risk, the Department of Health said.


High numbers of malaria cases are being reported in the malaria transmission areas in northern South Africa, according to the department.


Vhembe and Mopani districts in Limpopo Province and Bushbuckridge in Mpumalanga Province are the most affected Portland Trail Blazers Women's Jersey , the department said without disclosing the number of reported malaria cases.


Compared to previous years, a modest increase in cases in the Kruger National Park and private game reserves in the area has been confirmed, department spokesperson Popo Maja said.


This follows a very busy 2017 malaria season in the entire Southern African region, which peaked in April and May and extended into June.


High rainfall, humidity and ambient temperatures provided ideal conditions for malaria mosquito breeding and contributed to an increase in malaria cases, Maja said.


According to the South African National Institute for Communicable Diseases Phoenix Suns Women's Jersey , unusual malaria cases, affecting persons with no recent history of travel to malaria transmission areas, have been reported in Pretoria and some other nearby places. One patient has died.


The key prevention strategy of the malaria control programs in endemic areas is spraying of households with long acting residual insecticides, or indoor residual spraying (IRS), which target indoor feeding mosquitos.


This IRS program is in progress in both Limpopo and Mpumalanga and is planned to target a larger area than in 2016, Maja said.


Travellers from or residents of malaria transmission areas in Limpopo and Mpumalanga Philadelphia 76ers Women's Jersey , and the far northern KwaZulu-Natal and neighboring countries such as Mozambique, Botswana, Zimbabwe and Namibia who present with fever and "flu-like" illness must have an urgent blood test and malaria treated as a medical emergency, Maja said.


Misdiagnosis of malaria as influenza is not uncommon with disastrous consequences in a number of persons, he cautioned.


The Department of Health in South Africa is ensuring universal coverage of key interventions, which include indoor residual spraying Orlando Magic Women's Jersey , effective case management and distribution of prevention messages to communities at high risk, Maja said.


"All travellers to malaria risk areas must take precautions to prevent mosquito bites and medication to prevent malaria should be highly considered," Maja said.


Malaria symptoms include fever, headache, chills and vomiting, which appear within 10-15 days after the infective mosquito bite.


The life-threatening disease Oklahoma City Thunder Women's Jersey , transmitted to people through the bites of infected Anopheles mosquitoes, is preventable, treatable and curable.

HAIKOU, Oct. 23 (Xinhua) -- Deep in the silent sea, Huang Hui can hear only bubbles gurgling from her oxygen tank. She can only see a few meters around her Minnesota Timberwolves Women's Jersey , feeling small and alone.


She plants corals, the size of her palm, on the seafloor, hoping they one day become a forest.


If her dream is realized, the forest will have vivid colors, with fish weaving in and out.


A coral biologist with the South China Sea Institute of Oceanology under the Chinese Academy of Sciences New Orleans Pelicans Women's Jersey , Huang has studied coral for around 20 years. Now she and her team are building a large pilot zone and a demonstration area for coral planting in the South China Sea.

Coral is hailed as rain forest or life engine of the sea. Though it covers less than two thousandths of the seafloor area, it is the habitat of nearly 30 percent of marine species, making coral reefs among the most diverse ecosystems on the planet.


Globally coral provides a living for half a billion people, generating billions of dollars of revenue from tourism and fishing. The South China Sea accounts for 2.57 percent of the resources around the globe, ranking eighth in the world.


Corals require precise living conditions: water can neither be too hot nor too cold New York Knicks Women's Jersey , the ideal temperature ranging from 23 to 27 degrees centigrade; hydraulic pressure cannot be too high; salinity must be moderate and stable; and the environment must be clean.


Corals have a symbiotic relationship with zooxanthellae algae, which live in coral and give it nutrition and color. If the environment is unsuitable, the zooxanthellae algae leave, and the coral turns white and dies.


Coral reef degradation tolls the alarm bell of climate change. More than a third of the world's coral reefs are severely degraded. Contributing factors include warmer waters, ocean acidification, seawater pollution Milwaukee Bucks Women's Jersey , increased UV radiation, destructive fishing and offshore construction. Scientists once predicted corals would be wiped out within 50 years, triggering a breakdown of the entire ocean ecosystem.


Huang still remembers the first time she went underwater. It was in 2002 in the South Chi" Chilean presidential.
