In many countries neonatal tetanus is responsible for half of all neonatal deaths due to vaccine-preventable diseases and for almost 14% of al¡ infant deaths. It is estimated that in the 1970s more than 10,000 newborns died annually from neonatal tetanus in the Americas. Neonatal tetanus is prevent...ed by immunization and/or assuring clean delivery and post-delivery practices.

Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

Chloroquine and hydroxychloroquine are known to potentially cause heart rhythm problems, and these could be exacerbated if treatment is combined with other medicines, such as the antibiotic azithromycin, that have similar effects on the heart.

The overall objective of this prospective meta-analyses (PMA) is to estimate the effect of anti-IL-6 therapy compared with usual care in hospitalized patients with suspected or confirmed COVID-19. The primary comparison is of the class effect of anti-IL-6 therapies. It will also es...timate the effects of specific anti-IL-6 therapies.

WHO has a unique combination of technical public health and scientific expertise, and a global operational footprint, with field offices in more than 150 countries. In 2020, this global, technical, and operational reach meant WHO was able to support countries around the world in every aspect of COVI...D-19 public health response, from surveillance and laboratory testing to maintaining essential health services in the most vulnerable and fragile contexts.

The Guidelines for the Prevention, Surveillance and Management of COVID-19 Infection amongst Health Care Workers (HCW) in Zimbabwe were developed to prevent, detect and manage HCW COVID-19 infection, an emerging pandemic affecting the whole world. The HCW is at the fore front of this pandemic, thus ...the need for standardised operating procedures is of utmost importance. These guidelines therefore seek to reduce the significant morbidity and mortality among the HCW, ultimately ensuring the reduction of the cost to the health care worker and the Ministry of Health and Child Care (MoHCC) as a whole. The Ministry of Health and Child Care requires that all health care workers in various health care settings follow infection prevention and control procedures.

Après plus de trois ans sans cas, Haïti a signalé le 2 octobre 2022 un ensemble de cas de choléra dans la zone métropolitaine de Port-au-Prince, alors que le pays était sur le point d'être déclaré exempt de choléra.
Cette résurgence du choléra en Haïti survient dans un contexte opér...ationnel complexe, au milieu d'un environnement socio-politique instable marqué par des blocus, des pénuries de carburant, des activités de bandes criminelles et une insécurité galopante. Les troubles civils et le manque d'accès aux communautés touchées aggravent la crise humanitaire complexe et entravent les efforts de réponse d'urgence.

After more than three years without cases, Haiti reported on 2 October 2022 a cluster of cholera cases in the metropolitan area of Port-au-Prince, just as the country was on the verge of being declared cholera- free.
This cholera resurgence in Haiti is happening in a complex operational context, ...amid a volatile socio- political environment marked by blockades, fuel shortages, criminal gang activity and rampant insecurity. Civil unrest and lack of access to the affected communities are deepening the complex humanitarian crisis and hindering emergency response efforts.

In 2005, the World Health Organization (WHO) recognized Chagas disease (CD; Trypanosoma cruzi infection) as a neglected tropical disease (NTD) [1] and included it into the global plan to combat NTDs [2]. The Target 3.3 of the United Nations Sustainable Development Goals (UN/SDG) aims at ending the e...pidemics of NTDs by 2030 [3]. Mother-to-child (congenital/connatal) transmission is currently the main mode of transmission of T. cruzi over blood transfusions and organ transplantations in vector-free areas within and outside Latin America (LA). Based on recent demonstrations that congenital transmission can be prevented [4–7], WHO has shifted its objective, in 2018, from control to elimination of congenital CD (cCD).

Yaws is a disfiguring non-venereal disease caused by infection with the spirochaete. Treponema pallidum subspecies pertenue which is closely related to the causative agent of syphilis and those of the other endemic treponematoses, bejel and pinta. The disease is endemic in certain areas of the World... Health Organization (WHO) African, South-East Asia and Western Pacific regions. Of the neglected tropical diseases identified for elimination and eradication, yaws is one of two diseases targeted for eradication. In 1949, the Second World Health Assembly adopted resolution WHA2.36, which addresses yaws, bejel and pinta as major public health problems that need attention.

Rabies is a fatal viral disease, but is preventable in humans. The rabies virus is transmitted to humans through virus-laden saliva from a rabid animal, mostly dogs. The virus is shed in the saliva of an infected animal and can be introduced into another body through bites, scratches and any other ...wounds that transect the skin. Contact of the infected saliva with mucous membranes is also thought to be a possible route of infection, whereas contact of infected saliva with intact skin is not considered an exposure. Rabies is preventable through pre-exposure prophylaxis (PrEP) for individuals at high and continual risk, and post-exposure prophylaxis (PEP).

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.
