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.

This field action guide focuses on the first psychosocial assessment to be conducted just after a calamity strikes or just after a major event in an ongoing armed conflict. While it is necessary to update that initial assessment as the emergency situation evolves through the different phases of reco...very (briefly outlined in the “phase chart”), this mini book is meant to guide the formation of a team to assess the psychosocial as well as physical needs of children, their families and the communities and then the recommendations the team makes for ensuing support.

History has shown that governments tend to deprioritize environmental commitments during times of financial and public crises as they work to mitigate immediate needs—and the age of COVID-19 has been no different. Even though human interaction with wildlife is believed to be the cause of the pande...mic, the focus on COVID’s fallout has deprioritized the importance of reversing the damage humans have done to the planet.
COVID has had a multifaceted and detrimental effect on environmental conservation. Not only has funding been diverted to deal with the pandemic, conservation-oriented organizations are operating with minimal staff or have closed entirely. People whose daily work it is to advance environmental science and protect the land and water have become ill or have been forced to stay home because of travel restrictions. Plastic use is at an all-time high.
The good news is that there is an unprecedented opportunity for philanthropy to recharge the effort to protect the planet. This Giving Smarter Guide examines the state of environmental philanthropy, and provides an overview of potential strategic starting points for philanthropy and impact capital to play a role in saving the planet. In addition to offering recommendations specific to the COVID-19 response, the Center for Strategic Philanthropy also asks the questions that philanthropists should consider at the start of their journey into the field of conservation philanthropy.

Progress was made on policies favouring inclusion and integration into national systems3 with 92% of 48 operations surveyed reporting refuge...es having access to national primary health care facilities under the same conditions as nationals and 96% reporting refugees having access to all relevant vaccines under the same conditions as nationals. While many refugee hosting countries have policies that allow refugees to access national health services, many face partial access, prohibitive out-of-pocket expenditures and other barriers including distance to facilities, language and provider acceptance. Furthermore, more work is needed on strengthening these systems to be able to meet the needs of both host communities and refugees.
