Fever is difficult to detect, can lead to death

Patients with febrile illness are likely to die if not detected in time.

According to the Department of Preventive Medicine (Ministry of Health), febrile illness is transmitted from mite larvae infected with R.orientalis infection and transmitted to humans; disease is not transmitted from person to person.

September and October are easy to develop diseases . People with this disease often have fever but are unexplained, it is difficult to detect, so they need specific knowledge about the disease to treat and monitor.

Larvae are mites, spider mites, arthropods, small sizes less than 1 mm, yellow and orange colors; also known as red goose . In the larval stage, gnawing is usually parasitic in mice, small animals and capable of burning people.

The vector of infection is a red mite larvae (Leptotrombidium akamushi and L. deliense) . Immediately after hatching the red mite larvae already carry pathogens. They crawl on grass or leaves waiting for a host to be human or animal to cling to blood. In humans, red gnawing often bites in enclosed areas.

The red mite larvae have 6 legs, are hairy and cannot be detected with the naked eye. Once clinging to people, they usually burn for 3-8 days and create sores that are painless or itchy so it is difficult to detect.

Burning spots often have ulcers.

Expression of the disease

When being infected with germs, the patients will incubate an average of 8-12 days. At first, where the larvae burned with a nodule of pea-sized water, there was no pain, patients often did not pay attention. After a few days, the disease comes with symptoms such as high fever from 38-40 degrees C, continuous fever, lasts about 15-20 days, even up to 27 days without treatment. In the first 1-2 days, there may be tremor, accompanied by severe headache, muscle aches.

Occurrence of characteristic ulcers of the disease in the area of ​​soft and moist skin such as genital area, cystic area, anus, groin, armpit, neck . sometimes in unexpected position in the ear, belly button , eye lashes (easily mistaken for strabismus). Characteristics of ulcers are painless, non-itchy; The patient usually has only one note, circle or oval, diameter of 1mm - 2 cm. Initial burns develop gradually into cloudy fluid, after 4 - 5 days break.

Lymph nodes appear at the same time as fever or after fever for 2-3 days at the area of ​​the ulcer, the touch often feels swollen and painful.

Along with lymph nodes, the rash appears after about a week of fever, and the nodule is more pronounced than that of Dengue. Ban grows all over the body, except for the palm of the foot, lasts for a few hours to a week.

Severe patients often have symptoms such as: faint heartbeat, low blood pressure, slow pulse compared to temperature, nosebleeds, bronchitis, atypical pneumonia .

In addition, febrile illness may not be characterized by ulcers, so it is difficult to detect.

The disease must be treated with appropriate antibiotics. If late or ineffective intervention can have complications such as myocarditis, septic shock, pneumonia, respiratory failure, encephalitis, meningitis . very dangerous.

How to prevent disease

The main preventive measure is to prevent burning stings by: Avoid sitting, lying, or drying clothes, putting backpacks on the grass, near the bush, tree stumps. When going to the fields for slash-and-burn cultivation, field operations, and reconnaissance into the forest, it is necessary to wear shoes and socks, to tighten pants to avoid sticking to the body and burning.

Impregnate clothes with groping agents (permethrine and benzyl benzoate) or rub your limbs with a pickling medication (diethyltoluamid, DEET).

Kill mites in the environment by spraying antiseptic drugs such as Diazinon, fenthion, malathion, lindane, dieldrin, chlordan . into moist soil, bushes of grass under 20 cm high around the house, shady place.

Conducting rat killing is the host species for parasitic larvae.

Luminescence, environmental sanitation to avoid nesting.
