Man's feet infected with mites

Qiang typhus, also known as jungle typhus or red worm disease, is an acute fever mainly caused by the bites of the larvae of tsutsugamushi Rickettsia. It has a certain incubation period and is prone to symptoms such as headache, coma, fever, etc. More serious cases can even lead to shock, cardiac failure, etc. Patients should rest in bed, actively take medication, and strengthen dietary adjustments.

Treatment options

1. General treatment is to rest in bed, eat easily digestible food, strengthen care, pay attention to oral hygiene, and turn over regularly. Drink plenty of water and make sure to get enough water. High fever can be reduced by physical measures such as ice compresses and ethanol baths. Antipyretics can be used as appropriate, but antipyretics that induce excessive sweating should be used with caution. When you are restless, you can use sedatives and. 2. Pathogen treatment: Chloramphenicol is particularly effective for this disease. After taking the medicine, the body temperature will gradually return to normal within 1-3 days. The dosage is 2g/d for adults and 25-40mg/kg/d for children, divided into 4 doses. For those who have difficulty taking the medicine orally, it can also be given by intravenous drip. After the fever subsides, the dose is halved and continued for another 7-10 days. Tetracyclines can also achieve satisfactory therapeutic effects. Doxycycline can be used as an option. The adult dose is 0.2g, once a day, for 5-7 consecutive days. Other drugs such as roxithromycin, azithromycin, and erythromycin also have certain therapeutic effects and can be used by children who are not suitable for using tetracyclines. The dosage of roxithromycin is 0.6g/d for adults and 2-3mg/kg/d for children, divided into 2 doses. The dose is halved after the fever subsides. The course of treatment is 10 days.

Disease prevention

Prognosis: If untreated, the mortality rate ranges from 0% to 30%, depending on virulence and resistance factors; with treatment, no mortality is expected. Secondary and tertiary attacks of scrub typhus caused by different serotypes are generally mild, with no eschar or rash. It has been confirmed that Orientia tsutsugamushi is still present in lymph node tissue one year after recovery, indicating that the disease may still be reactivated during immunosuppression. Prevention: Vaccines were developed and tested during and after World War II. Some are effective against homologous strains, but there is no antigen that can induce protection against all antigenically different strains of Orientia tsutsugamushi. Troops in epidemic areas can take a dose of doxycycline once a week to prevent scrub typhus.
