While none of the main four species of malaria parasite that cause human infections are known to have animal reservoirs, [360] P. knowlesi is known to infect both humans and non-human primates. [52] Other non-human primate malarias (particularly P. cynomolgi and P. simium) have also been found to have spilled over into humans. [361]
The recent spread of Dengue can also be attributed to rapid population growth, increased coagulation in urban areas, and global travel. Without sufficient vector control, the dengue virus has evolved rapidly over time, posing challenges to both government and public health officials. [62] Malaria is caused by a protozoan called Plasmodium ...
Dengue fever is a mosquito-borne disease caused by dengue virus, prevalent in tropical and subtropical areas. It is frequently asymptomatic; if symptoms appear, they typically begin 3 to 14 days after infection. These may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin itching and skin rash. Recovery ...
The symptoms experienced by those infected with dengue can vary widely: up to 80% of dengue cases are asymptomatic, and while some infections may trigger only flu-like symptoms, more serious cases ...
Dengue virus (DENV) is the cause of dengue fever.It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. [1] [2] Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, [3] [4] [5] all of which can cause the full spectrum of disease. [1]
Plasmodium knowlesi is a parasite that causes malaria in humans and other primates. It is found throughout Southeast Asia , and is the most common cause of human malaria in Malaysia . Like other Plasmodium species, P. knowlesi has a life cycle that requires infection of both a mosquito and a warm-blooded host.
Dengue symptoms include a high fever, headache, vomiting, skin rash, and muscle and joint pain that can be so severe the disease has been called "break-bone" fever.
For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus. Although invertebrate-transmitted diseases pose a particular threat on the continents of Africa, Asia and South America, there is one way of controlling invertebrate-borne diseases, which is by controlling the invertebrate vector.
