In this first part of the book, we have highlighted that infectious diseases still impose a very high burden on populations living in low-income countries, with millions of deaths every year attributable to pathogens that have (almost) disappeared in high-income countries (such as malaria or tuberculosis). Numerous public health programs at a global scale are trying to diminish this burden through multiple interventions, involving vaccines, antibiotics, drugs and vector control, among others. Many of these global programs have been extremely successful, but their impacts have been much more striking in high-income countries than in low-income countries, where, despite noticeable successes, achievements are fragile, sustainability is uncertain and there are still many possible improvements....

The Status

College students represent a large group of people who frequently travel across regions, which increased their risk of infection and exacerbated the risk of COVID-19 spread throughout China. This study uses survey data from the end of April 2020 to analyze the status of COVID-19-infected cases, the group differences, and influencing factors in college students in Wuhan. The sample size was made up 4355 participants, including 70 COVID-19-infected students. We found that during the COVID-19 outbreak in early 2020, college students in Wuhan were primarily infected during off-campus events after winter break or infected in their hometowns after leaving Wuhan; the percentage of college students with severe cases was relatively low, and most had mild cases; however, a large proportion of asymptomatic cases may exist; there were significant group differences in gender, age and place of residence; and the risk of infection was closely related to the campus environment, in which the population density and number of faculty and students on campus had a significant impact. The results indicated that the infection of students did not occur at random, thus strengthening student health education and campus management can help curb the spread of COVID-19 among students.

Antiparasitic Treatment

INTRODUCTION: Chagas disease is considered the most serious parasitosis in America, forgotten and neglected in the world, with a characteristic that has its maximum expression in the difficulties and limitations for its diagnosis and treatment. OBJECTIVE: To assess the status of seropositivity of Chagas disease in Mexico, in addition to monitoring the effectiveness of treatment in infected patients. MATERIAL AND METHODS: Systematic reviews were conducted, with searches in Crossref, Google Scholar, Scielo, PubMed and the inclusion of guides and manuals of related health programs was evaluated based on their titles, news and relevance. RESULTS: for seropositivity, the data coincide with 100% in the characterization of the risk factors, as well as in the evaluations in the Blood Transfusion Centers of the country, finding captive cases in each state that explain the persistence of the disease . When monitoring treatments and evidence of effectiveness, the following difficulties arise: prolonged duration and side effects, adding the lack of reliable healing criteria, with an effectiveness of 60-75% in acute cases and in 100% of acute congenital cases, and in chronic cases a variation of between 15 and 30 years was found. CONCLUSIONS: Although the achievements have been commendable in reducing rates, the territory has factors that allow the redistribution of the infection, the evidence on the effectiveness is scarce, there is no evidence of epidemiological follow-up of cases in Mexico with respect to healing indicator.

One measure of the maturity of a device technology is the ease and reliability of applying contact metallurgy. Compared to metal contact of silicon, the status of GaAs metallization is still at its primitive stage. With the advent of GaAs MESFET and integrated circuits, very stringent requirements were placed on their metal contacts. During the past few years, extensive researches have been conducted in the area of Au-Ge-Ni in order to lower contact resistances and improve uniformity. In this paper, we report the results of TEM study of interfacial reactions between Ni and GaAs as part of the attempt to understand the role of nickel in Au-Ge-Ni contact of GaAs.N-type, Si-doped, (001) oriented GaAs wafers, 15 mil in thickness, were grown by gradient-freeze method. Nickel thin films, 300Å in thickness, were e-gun deposited on GaAs wafers. The samples were then annealed in dry N2 in a 3-zone diffusion furnace at temperatures 200°C - 600°C for 5-180 minutes. Thin foils for TEM examinations were prepared by chemical polishing from the GaA.s side. TEM investigations were performed with JE0L- 100B and JE0L-200CX electron microscopes.
