In 2015, a rapid antigen test which gives results in 15 minutes was approved for use by WHO. It is able to confirm Ebola in 92% of those affected and rule it out in 85% of those not affected. Differential diagnosis
Early symptoms of EVD may be similar to those of other diseases common in Africa, including malaria and dengue fever. The symptoms are also similar to those of other viral haemorrhagic fevers such as Marburg virus disease, Crimean–Congo haemorrhagic fever, and Lassa fever.The complete differential diagnosis is extensive and requires consideration of many other infectious diseases such as typhoid fever, shigellosis, rickettsial diseases, cholera, sepsis, borreliosis, EHEC enteritis, leptospirosis, scrub typhus, plague, Q fever, candidiasis, histoplasmosis, trypanosomiasis, visceral leishmaniasis, measles, and viral hepatitis among others.Non-infectious diseases that may result in symptoms similar to those of EVD include acute promyelocytic leukaemia, haemolytic uraemic syndrome, snake envenomation, clotting factor deficiencies/platelet disorders, thrombotic thrombocytopenic purpura, hereditary haemorrhagic telangiectasia, Kawasaki disease, and warfarin poisoning. Prevention
Vaccines
An Ebola vaccine, rVSV-ZEBOV, was approved in the United States in December 2019. It appears to be fully effective ten days after being given. It was studied in Guinea between 2014 and 2016. More than 100,000 people have been vaccinated against Ebola as of 2019. Infection control
Caregivers
People who care for those infected with Ebola should wear protective clothing including masks, gloves, gowns and goggles. The U.S. Centers for Disease Control (CDC) recommend that the protective gear leaves no skin exposed.
Whether other mutants are able to traffic properly to the surface or coassemble has not yet been further studied.While the hypomagnesemia in patients with HSH is a direct result of TRPM6 mutations, hypocalcemia is an indirect, secondary result. Parathyroid gland secretion of PTH can be altered by changes in serum magnesium levels. The decreased serum magnesium levels seen in HSH result in decreased PTH secretion. PTH, in turn, controls the availability of serum calcium. Decreasing PTH levels cause a decrease in calcium availability in serum and, thus, the neurological symptoms of HSH. Diagnosis
Diagnosis typically occurs during the first 6 months of life due to characteristic neurological symptoms. These symptoms include muscle spasms, tetany, and seizures. Laboratory testing indicates hypomagnesemia (decreased serum magnesium levels), hypocalcemia (decreased serum calcium levels), and little to no measurable parathyroid hormone levels. Diagnosis is confirmed with these symptoms and can be further solidified with genetic sequencing of the TRPM6 gene. Treatment
Treatment of HSH involves administration of high doses of magnesium salts. These salts may be taken orally or otherwise (e.g. subcutaneously). This treatment works by increasing magnesium absorption through the non-TRPM6 mediated paracellular uptake pathways. This treatment must be continued throughout life. History
HSH was originally believed to be an X-linked disorder due to the preponderance of affected males. With the finding that mutations in TRPM6 (on chromosome 9) are causative for the disorder this is no longer the case.
