Is There No Risk Of Malaria?

Parasitical Worms.com Fever is a disease caused by the agent Orientia tsutsugamushi, which has a natural outbreak, is transmitted randomly to humans when it is bitten by larvae.
Epidemiology of malaria disease
The disease is mainly distributed in Asia (Central Asia, East Asia, Southeast Asia and the Western Pacific), from Japan to Pakistan, from North Korea to North Australia, and the nature of small outbreaks (Typhus Island). on the margins of forests, newly planted or newly planted forests, adjacent areas, where many shrubs, grasses along rivers and streams, upland fields, shady spots and moist soil, even desert areas New excavations and high mountains Hymalayia also.
All ages are affected by disease, but the disease is mainly distributed at the working age, the distribution of occupation, forestry, agriculture and soldiers; The disease is mainly found in mountainous and rural areas (80

.5%), rarely in urban areas. In temperate and tropical areas, the disease develops in the summer and the rainy months with high humidity is the time for fever index. The disease occurs in Vietnam all year round but mainly in the rainy season from April to September, October, peaking in June-July Army training picnic
RESOURCES OF POLICY DISEASES
- Source of disease: wild animals: rodents (mainly rats), rabbits, pigs, birds, or cattle (dogs, pigs, chickens) ..



..
- Transmission vector: The pathogen is Orientia tsutsugamushi (also called R.orientalis, or R.tsutsugamushi). The larvae were infected with R orientalis when sucking the host blood with a pathogen; The larvae then develop into adult larvae and lay eggs The larvae hatch into larvae and are ready to suck blood (mites can transmit germs through eggs to the third generation).
These later larvae will infect other animals and humans by burning and sucking blood. thus, it is both a host and a vector for disease transmission. The infection process is maintained in the wild between mites and rodents, etc.



., and due to the transmission of pathogens through later generations of mites. Stinging and sucking human blood, transmitting R.orientalis to humans is just a coincidence.
- Transmission conditions: Leptotrombidium mites often live in the bushes, damp grass bushes .. above the tall canopy of trees; or in caves with live rodents. As a result, people often get fever when passing through or working in these places such as: combat troops, hunters, slash-and-burn fields, etc. into the caves.
Manifestations of malaria
1.



. Typical common form:
Incubation period: average from 8 to 12 days, early as 6 days, long as 21 days.
Onset period:
At the site of the incision, there is a blister, which is only one day after the bite, but the patient does not know because there is no pain, itching or itching The disease has reached an advanced stage. This bulge will then become an ulcer.
Full-time period:
1. Toxic infection syndrome: often severe and early symptoms of the disease with the following symptoms:
- Mild fever for the first 1 to 2 days, after a constant high fever; There are also many cases of sudden high fever right at 39 - 40 ° c in the first day like malaria.
- A persistent high fever around 40 ° c plateau or intermittent type lasting for 15 to 20 days. If not treated, the pulse is often dissociated like typhoid.
- Neurotoxicity is often severe, headache is the first sign, headache throughout the head, can hurt both eyes.
- Fatigue, discomfort, dizziness, lightheadedness, unsteady movements, tinnitus, trembling tongue, sweating, muscle aches as much as in leptospirosis - there are cases of lethargy renders as in typhoid.




2. Ulcerative syndrome - lymph nodes - rash:
- Ulcers: Ulcers are common in many places throughout the body, usually in young and moist skin. more common is genital; armpits, groin, then anus, groin, back, back to limbs, back, chest, abdomen, neck, sometimes ulcers in quite unexpected positions such as the ears, navel, eyelids.
The ulcer is usually round or oval, small diameter is 1mm, to large is 2 cm. if present, then black scales, hard covering on a hard bumps. If the scales have flaked, they will leave a concave ulcer, bright red, no discharge, no pus. the patient did not know there was an ulcer because there was no pain, no itching, no irritation, burning. By the 3rd week, the sores heal, the skin returns to normal
-Lymphadenopathy: There are 2 types of lymphadenopathy: Primary regional lymphadenitis and secondary systemic lymphadenitis.
- Ban: appears at the end of the first week and the second week of the disease.



. Usually maculopapular rash, size from millet to 1 cm in diameter. grows all over the body (back, chest, abdomen, limbs) except the palms, soles of the feet, about 10% have petechiae. The rash lasts from a few hours to a week.
3. Cardiovascular and vascular syndrome: very common heart damage in fever like:
- Vasodilation causes skin to be ruddy, conjunctival hyperemia with red blood (this is a symptom to distinguish malaria and typhoid) Sometimes there are cases of subcutaneous hemorrhage, epistaxis, gastrointestinal bleeding, hemoptysis ..
- Or manifestations of myocarditis: g.
