Undulating fever: features, symptoms and treatment
Undulating fever (f. undulans) is an infectious disease characterized by periodic episodes of high fever, muscle pain and other unpleasant symptoms. It is a type of hemorrhagic fever and is caused by a virus transmitted through the bites of infected mosquitoes.
Although undulating fever virus occurs in various regions of the world, particularly high incidence rates have been reported in tropical and subtropical areas of Africa, Southeast Asia, and the Pacific region. People living or traveling to these regions have an increased risk of infection.
The main vector of transmission of the virus is the Aedes mosquito, which becomes infected by feeding on the blood of an infected person. Once infected, the virus begins to multiply in mosquitoes, and they become a source of transmission through their bites.
The incubation period for undulating fever can vary from 3 to 14 days. After this, the disease manifests itself in several phases. In the initial phase, patients often experience headaches, fever, muscle and joint pain, fatigue and general weakness. During the next phase, the temperature may decrease and symptoms may subside. However, after a few days they recur and become more pronounced. Some patients may also develop a rash, an enlarged liver and spleen, and bleeding from the gums or other organs.
The diagnosis of undulating fever is made on the basis of clinical symptoms and laboratory tests. It is important to consider the epidemiological context and patient history, as symptoms may be similar to other infectious diseases.
There is no specific treatment for undulating fever, and most cases require only symptomatic treatment to relieve unpleasant symptoms. It is important to provide the patient with rest, adequate fluids, and symptomatic relief of pain and fever. In more severe cases, hospitalization may be required to maintain vital signs and control bleeding.
Prevention of undulating fever includes controlling the mosquito population and preventing mosquito bites by using window nets, repellent and protective clothing. It is also recommended to avoid being outdoors during the most active period of mosquitoes, usually dawn and dusk.
There is currently no vaccine against undulating fever. However, for those planning to travel to endemic areas, it is recommended to consult a doctor and take precautions such as using repellents and protection against mosquito bites.
Undulating fever can be a serious illness, especially in people with weakened immune systems or in children. Therefore, it is important to consult a medical specialist if you suspect this disease.
In conclusion, undulating fever is an infectious disease transmitted through the bites of infected mosquitoes. It is characterized by periodic episodes of high fever accompanied by other symptoms. It is important to take preventative measures such as controlling mosquito populations and protecting against bites, especially when traveling to endemic areas.
