Vaccination has proven effective at controlling outbreaks in high-incidence areas and is also very cost-effective: prices are normally less than US$1 per dose. Because the price is low, poverty-stricken communities are more willing to take advantage of the vaccinations. Although vaccination programs for typhoid have proven effective, they alone cannot eliminate typhoid fever. Combining vaccines with public-health efforts is the only proven way to control this disease.Since the 1990s, the WHO has recommended two typhoid fever vaccines. The ViPS vaccine is given by injection, and the Ty21a by capsules. Only people over age two are recommended to be vaccinated with the ViPS vaccine, and it requires a revaccination after 2–3 years, with a 55%–72% efficacy. The Ty21a vaccine is recommended for people five and older, lasting 5–7 years with 51%–67% efficacy. The two vaccines have proved safe and effective for epidemic disease control in multiple regions.A version of the vaccine combined with a hepatitis A vaccine is also available.Results of a phase 3 trial of typhoid conjugate vaccine (TCV) in December 2019 reported 81% fewer cases among children. Treatment
Oral rehydration therapy
The rediscovery of oral rehydration therapy in the 1960s provided a simple way to prevent many of the deaths of diarrheal diseases in general. Antibiotics
Where resistance is uncommon, the treatment of choice is a fluoroquinolone such as ciprofloxacin. Otherwise, a third-generation cephalosporin such as ceftriaxone or cefotaxime is the first choice. Cefixime is a suitable oral alternative.Properly treated, typhoid fever is not fatal in most cases.
Tinea manuum is a fungal infection of the hand, mostly a type of dermatophytosis, often part of two feet-one hand syndrome. There is diffuse scaling on the palms or back of usually one hand and the palmer creases appear more prominent. When both hands are affected, the rash looks different on each hand, with palmer creases appearing whitish if the infection has been present for a long time. It can be itchy and look slightly raised. Nails may also be affected.The most common cause is Trichophyton rubrum. The infection can result from touching another area of the body with a fungal infection such as athletes foot or fungal infection of groin, contact with an infected person or animal, or from contact with soil or contaminated towels. Risk factors include diabetes, high blood pressure, weak immune system, humid surroundings, excessive sweating, recurrent hand trauma and cracks in feet. Pet owners and farmworkers are also at higher risk. Machine operators, mechanics, gas/electricity workers and people who work with chemicals have also been reported to be at greater risk.Diagnosis is by visualization, direct microscopy and culture. Psoriasis of the palms, pompholyx and contact dermatitis may appear similar. Treatment is usually with long-term topical antifungal medications. If not resolving, terbinafine or itraconazole taken by mouth might be options.It occurs worldwide.
