Patients with retreatment tuberculosis (TB) represent those
who have been treated previously for onemonth ormorewith
anti-TB drugs and who have been diagnosed once again with
the disease.These patientsmainly include relapses, treatment
after failure, or loss to follow-up on a first-line treatmen...t
regimen [1]. The number of these patients is not negligible.
In 2014, of the 6.3 million TB cases that were notified
by National TB Programmes (NTPs) to the World Health
Organization (WHO), approximately 700,000 patients were
already previously treated

Stay-at-home restrictions and other measures restricting the movement of people contribute to an increase in genderbased violence, a finding confirmed by media reports, official ...statements and information received from OHCHR field presences and human rights defenders in many countries.
Women and girls already in abusive situations are more exposed to increased control and restrictions by their abusers, with little or no recourse to seek support. Hotlines receive reports of women being threatened with being thrown out of their homes, exposed to the infection, or having financial resources and medical aid withheld.

Primary care can play a significant role in the COVID-19 response by differentiating patients with respiratory symptoms from those with COVID-19, making an early diagnosis, helping vulnerable people cope with their anxiety about the virus, and reducing the demand for hospital services. This document... provides national and subnational health managers, as well as staff at primary care facilities, with interim guidance on timely, effective and safe supportive management of patients with suspected and confirmed COVID-19 at the primary care level; and delivery of essential health services at the primary care level during the COVID-19 outbreak

Mothers and healthcare workers who support them have many questions and concerns about whether it is safe for mothers with confirmed or suspected COVID-19 to be close to and breastfeed their babies during the pandemic.
To address their questions, WHO has released a list of Frequently asked question...s: Breastfeeding and COVID-19. The FAQ complements the WHO interim guidance: Clinical management of severe acute respiratory infection when COVID-19 is suspected and draws upon other WHO recommendations on infant and young child feeding.
The FAQs aim to provide information to healthcare workers supporting mothers and families in maternity services and community settings, and communicate how the interim guidance should be implemented. Additionally, the FAQs provide information about the protective effects of breastfeeding and skin-to-skin contact, and the harmful effects of inappropriate use of infant formula milk.

As of 12June 2020, there are 667confirmed COVID-19 casesin the OPT (565 of which are recovered cases), and 48% of which (320 cases) are in East Jerusalem and its suburbs. Additionally, there have been 5 reported COVID-19 deaths (1 in the West Bank, 1 in Gaza and 3 in East Jerusalem)
For COVID-19, as for many infectious diseases, the true level of transmission is frequently underestimated because a substantial proportion of people with the infection are undetected either because they are asymptomatic or have only mild symptoms and thus typically fail to present at healthcare fac...ilities. There may also be neglected or under-served segments of the population who are less likely to access healthcare or testing. Under-detection of cases may be exacerbated during an epidemic, when testing capacity may be limited and restricted to people with severe cases and priority risk groups (such as frontline healthcare workers, elderly people and people with comorbidities). Cases may also be misdiagnosed and attributed to other diseases with similar clinical presentation, such as influenza.
Differences in mortality between groups of people and countries are important proxy indicators of relative risk of death that guide policy decisions regarding scarce medical resource allocation during the ongoing COVID-19 pandemic. This document is intended to help countries estimate CFR and, if possible, IFR, as appropriately and accurately as possible, while accounting for possible biases in their estimation

Systematic screening for TB disease is the systematic identification of people at risk for TB disease, in a predetermined target group, by assessing symptoms and using tests, examinations or other procedures that can be applied rapidly.
Systematic screening can benefit people who are at risk of get...ting TB, as early detection and start of treatment can improve their outcomes and reduce their costs. It can also benefit entire communities at higher risk for TB, by reducing the prevalence of TB disease and preventing future cases.

SARS-CoV-2 infections among children and adolescents cause less severe illness and fewer deaths compared to adults. While a less severe course of infection is a positive outcome, there are concerns that mild symptoms may have led to less testing, resulting in fewer identified cases of COVID-19 in ch...ildren. If children with mild or no symptoms transmit the disease, they may act as drivers of transmission within their communities. Understanding symptoms, infectivity and patterns of SARS-CoV-2 transmission in children and adolescents is essential for developing, adapting and improving control measures for COVID-19 across all ages. This is a summary of the current knowledge around SARS-CoV-2 infection acquisition and transmission and COVID-19 disease symptoms in children and adolescents. It aims to inform decisions, based on local contexts, on how to best keep schools, kindergarten and day-care facilities open and what advice to apply to intergenerational mixing.

Brazil created the Emergency Operations Center (COE) and immediately notified WHO when the first case in Brazilian territory
was confirmed on February 26.
The sub-Saharan African region, carries 90% of the over 250 million cases of schistosomiasis occurring worldwide. In this region, after Nigeria, Tanzania is second country having the highest cases of schistosomiasis and approximately 51.5%0 of the Tanzanian population is either exposed or live in ar...eas with high risk of exposure. The country is endemic to both Schistosoma mansoni and Schistosoma haematobium, these infections are common in communities characterised with limited access to water, sanitation, hygienic practices and health services. Schistosoma mansoni infection is associated with hepatosplenic disease characterised with hepatomegaly, splenomegaly, progressive periportal fibrosis (PPF) which can lead to portal hypertension and its related sequelae, mainly ascites, liver surface irregularities, oesophageal varices and haematemesis. The main consequences of S. haematobium infection are haematuria, dysuria, nutritional deficiencies, urinary bladder lesions, hydronephrosis, urinary bladder squamous cell carcinoma and in children, growth retardation. Preventive chemotherapy using mass drug administration (MDA) of praziquantel targeting primary school aged children is the main strategy for controlling schistosomiasis in Tanzania.

This country profile presents a summary and analysis of Argentina's status with yellow fever. It is part of a series of profiles on this topic, each focusing on a different country in the Region of the Americas. Argentina's geographical location presents a wide territorial extension throughout diffe...rent latitudes, which determines a wide climatic variety, maintaining the conditions for the enzootic transmission of the yellow fever virus in jungle areas of the northeast of the country bordering Brazil and Paraguay. After controlling the major urban epidemics that hit the port city of Buenos Aires in the 20th century, Argentina maintains foci of enzootic activity in the northeast and isolated human cases for jungle acquisition. The increases in viral activity usually occur in a regional context of epizootics that affect southern Brazil and eastern Paraguay. Argentina has not presented autochthonous cases since 2008. Outbreaks have been sporadic with long intervals without evidence of viral activity.

Since the last situation report on the multi-country outbreak of cholera was published on 6 July 2023 (covering data reported until 15 of June), and as of 15 July 2023, one new outbreak of cholera was reported from India on 15 May 2023. In total, 25 countries have reported cases since the beginning ...of 2023. The WHO African Region remains the most affected region with 14 countries reporting cholera cases since the beginning of the year. The overall capacity to respond to the multiple and simultaneous outbreaks continues to be strained due to the global lack of resources, including shortages of the Oral Cholera Vaccine (OCV) and cholera supplies, as well as overstretched public health and medical personnel, who are dealing with multiple parallel disease outbreaks and other health emergencies. Based on the large number of outbreaks and their geographic expansion, as well as a lack of vaccines and other resources, WHO continues to assess the risk at global level as very high.

The Democratic Republic of Timor-Leste has the highest TB incidence rate in the South East Asian Region - 498 per 100,000, which is the seventh highest in the world. In Timor-Leste TB is the eighth most common cause of death.
The salient observations are as follows:
In 2018, 487 (12.5%) of the... 3906 notified TB patients were tested for RR-TB and only 12 lab confirmed RR-TB patients were initiated on standard MDR-TB treatment of 20-months duration, (a 3-fold increase in RR-TB detection compared with 2017). This amounts to treatment coverage of only 17% of 72 estimated MDR/RR-TB among notified TB patients (3906) and 5% of 240 estimated incident MDR-TB patients as compared to 62% treatment coverage of 6300 incident drug sensitive TB patients estimated in TLS. The treatment success in the 2016 annual cohort of 6 MDR-TB patients has been reported at 83%. 80% of TB patients know their HIV Status with around 1% TB-HIV co-infection, 37/ 77 (48%) TB-HIV Co-infection Detected. Of the 387 PLHIV currently alive on ART, exact status on TB screening and testing is unknown. % of PLHIV newly enrolled in HIV care who received IPT is not known.
In 2018, the mortality rate for TB was 94 deaths per 100,000 people (1200 per annum) in TL with an increasing mortality trend (Figure 1), despite TB services being available for nearly two decades.
A survey of catastrophic costs due to TB (2016) highlights that 83% of TB patients are reported to be facing catastrophic costs due to the disease. This is the highest rate in the world.

Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.
