Fever disease

In the rainy season, people who go to the forest or work in farming should apply it to open skin of DEP, DEFA, tiger, eucalyptus oil . to avoid burning. This species infects the disease with a fever, and in severe cases, can be fatal.

Fever is also known as jungle fever or Tsutsugamushi. The outbreak is circulating in the Eastern Pacific regions, including Vietnam. This is an epidemic disease, there are three typical symptoms: ulcers, swollen glands and maculopapular rash. However, fever is also easily confused with many other fever diseases.

The source of disease is rodents, hamsters, some seabirds, dogs, chickens, pigs and rabbits. Infected insects are Trombiculae larvae. Larvae lying on the ground, grass, when meeting people or animals, cling to sucking blood to spread disease and leave people, continue to transform into mature gossips. Mo Mo grows much during the rainy months (May to November). The sick people are farmers, forest planters, soldiers marching in places with lots of bushes, cleaning spleen.

Incubation period 5-7 days, maybe 10 days without any sign. The onset of disease may be gradual, may be sudden. Patients with high fever of 39-41 degrees C, lasting 15-20 days, headache, dizziness, dizziness, tinnitus, sweating, pain in the back muscles, poor consciousness. Slow pulse, lower blood pressure. In the global period, there are symptoms of infection, systemic toxicity and 3 typical signs:

Ulcers: There are 80% of patients with fever. After 24 hours, the blister burns up, 2 mm in diameter, 4 days of cloudy fluid, 5 days of breakage, and the surrounding area is hard after closing the dark brown scales. The location of the ulcer is usually in a soft, moist, tight skin such as the genitals, anus, armpits, and groin; can be seen in the thigh, abdomen, neck, chest, back (mostly only 1 note, some cases 2 notes). When the sores go away, the skin around it is hard, scales brown. The ulcer is not itchy, no pain, so the patient does not pay attention to it.

Swollen lymph nodes: 91% of cases have lymph nodes in the area near the ulcer. Tongue with apple seeds, plum seeds, mobile, slightly painful. Full body lymph nodes are seen in the armpits, groin, neck (45%), often smaller than regional nodes.

Maculopapular rash: Grows on day 3 to day 6, with 82% of cases, diameter of millet to 1 cm, plum color, palpation. The whole body grows unordered, grows on the face, chest, abdomen, lasts 4-5 days.

Laboratory tests: Low white blood cells in the fever phase; lymphocytes increase; blood builds up; Weil Felix OXK reaction is positive.

If treated with appropriate antibiotics, only a few days of fever decreases, these signs will gradually recover and disappear. Severe cases often have complications in internal organs and nerves such as bronchitis, interstitial pneumonia, which can lead to respiratory failure, myocarditis, septic shock, intoxication, confusion. consciousness, meningitis, some coma. Death from complications is 1%.

Differential diagnosis with diseases with fever

Typhoid: Prolonged fever, lethargy, drowsiness. Abdominal bloating, constipation, sometimes loose, aching and gurgling in the right pelvic hole. Slow pulse.

Malaria: Severe fever, but normal. Test: White blood cells do not increase, red blood cells decrease, find malaria parasites in the blood.

Dengue fever : Fever lasts for several days. Red eyes, reddish skin. Bleeding rash develops at the time of fever reduction. There are also lymph nodes, but small and small. White blood cells do not increase.

The pulmonary complication of febrile fever should be distinguished from severe acute respiratory syndrome (SARS). SARS has symptoms of high fever that are suddenly over 38 degrees C; rapid pulse, headache, muscle aches, peripheral lymphadenopathy, sometimes diarrhea. X-ray of the lungs shows interstitial lesions. Blood tests showed increased white blood cells, reduced oxygen. In particular, SARS spreads strongly through air (respiratory), easily suffering from acute respiratory failure.
