Plos Current Outbreaks
An outbreak of Lassa Fever (LF) reported and confirmed in Ondo state, Southwest Nigeria in January 2016 was investigated. This paper provides the epidemiology of the LF and lessons learnt from the investigation of the outbreak.
Results: We identified 90 suspected LF case...s of which 19 were confirmed by the laboratory. More than half (52.6%) of the confirmed cases were females with majority (73.7%) in the age group ≥ 15 years. The Case Fatality Rate (CFR) of 63.2% among the laboratory-confirmed positive cases where 9 of 19 cases died, was significantly higher compared to the laboratory confirmed negative cases where 6 of the 65 cases died ( CFR; 8.5%) p ≤ 0.05. Two hundred and eighty-seven contacts of the confirmed cases were identified, out of which 267(93.0%) completed the follow-up without developing any symptoms and 2 (0.7%) developed symptoms consistent with LF and were confirmed by the laboratory. More than half of the contacts were females (64.5%) with most of them (89.2%) in the age group ≥ 25 years.

The technical note by the Global Task Force on Cholera Control (GTFCC) discusses the use of Oral Cholera Vaccines (OCVs) for international workers and travelers in cholera-affected areas. It reviews the effectiveness of WHO-prequalified vaccines (Dukoral®, Shanchol™, and Euvichol®), emphasizing ...their role in preventing infection and reducing transmission risks.
The document highlights concerns about travelers contracting cholera in endemic regions and potentially spreading the disease upon returning home. While the overall risk is considered low, certain groups, such as humanitarian workers and travelers to high-risk areas like South Asia, face a higher exposure.
Recommendations include vaccination for emergency and relief workers who may come into direct contact with cholera patients or contaminated environments. However, routine vaccination for general travelers is not widely recommended. The note also calls for better surveillance and studies to assess the potential of vaccines in preventing international transmission.

7 April 2022. Aimed at national policymakers, public health and healthcare planners, staff working in reception centres, and healthcare staff caring for displaced persons, the information note concludes that universal testing of incoming refugees from Ukraine for tuberculosis (TB) infection is not r...ecommended. Specific groups, such as household contacts of bacteriologically confirmed pulmonary cases, or those who are immunocompromised should however be considered for TB infection testing.

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.

Au Sénégal, la mortalité infanto-juvénile est surtout causée par le paludisme les maladies diarrhéiques et les infections respiratoires aigües (IRA). Des travaux ont montré que 80% des décès d’enfants de zéro à cinq ans (0 à 5 ans) surviennent dans les maisons ...sans aucun contact avec les services de santé. D’où la nécessité de mettre en place des interventions à base communautaire efficaces pour réduire cette mortalité. A ce propos, la problématique de la consolidation et de l’élargissement des interventions à base communautaire se pose avec beaucoup d’acuité.

Globally, in low-income countries, the average newborn mortality rate is 27 deaths per 1,000 births, the report says. In high-income countries, that rate is 3 deaths per 1,000. Newborns from the riskiest places to give birth are up to 50 times more likely to die than those from the safest places.
...>
The report also notes that 8 of the 10 most dangerous places to be born are in sub-Saharan Africa, where pregnant women are much less likely to receive assistance during delivery due to poverty, conflict and weak institutions. If every country brought its newborn mortality rate down to the high-income average by 2030, 16 million lives could be saved.
More than 80 per cent of newborn deaths are due to prematurity, complications during birth or infections such as pneumonia and sepsis, the report says. These deaths can be prevented with access to well-trained midwives, along with proven solutions like clean water, disinfectants, breastfeeding within the first hour, skin-to-skin contact and good nutrition.

Considered a neglected tropical disease, Guinea worm disease (dracunculiasis) is a parasitic infection caused by the nematode roundworm parasite Dracunculus medinensis. It is contracted when people consume water from stagnant sources contaminated with Guinea worm larvae. Inside a human's abdomen, Gu...inea worm larvae mate and female worms mature and grow. After about a year of incubation, the female Guinea worm, one meter long, creates an agonizingly painful lesion on the skin and slowly emerges from the body. Guinea worm sufferers may try to seek relief from the burning sensation caused by the emerging worm and immerse their limbs in water sources, but this contact with water stimulates the emerging worm to release its larvae into the water and begin the cycle of infection all over again.

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.
