#Mpox in #Africa: What we know and what is still lacking

Abstract

Emerging as a major global health threat, Mpox previously known as Monkeypox has drawn attention due to a worrying surge in cases. This zoonotic disease, native to Central and West Africa, is marked by fever, rash, and lymphadenopathy and is primarily spread through direct contact with infected animals or people and indirectly through contaminated objects. Recent studies have indicated possible sexual transmission, underscoring how human behavior and environmental changes are increasing its prevalence, even though human-to-human transmission is less efficient than that of smallpox. Mpox is endemic in several African countries, and currently, the infection has spread in non-endemic countries, including Rwanda, Uganda, and Kenya. Democratic Republic of Congo is the epicenter of the current Mpox outbreak. From January 1, 2022, to August 6, 2024, sixteen African countries reported Mpox outbreak. Several factors, including population immunity deficiencies and changes to the environment and ecology, have led to the widespread of Mpox in Africa. Challenges such as the fragile healthcare system, limited vaccine availability and access, weak surveillance, and low public awareness poses difficulty in containing the infection in affected countries. Given the potential of Mpox to disrupt several sectors including health systems, which may ultimately reverse progress in achieving the sustainable development goals by 2030. It is imperative for countries, both within and outside Africa, to extend financial aid and human resources to combat the infection effectively.

#Neuroinvasive #Oropouche virus in a patient with #HIV from extra-Amazonian #Brazil

{Excerpt} A novel reassortant Oropouche virus (OROV) lineage (with medium [M], large [L], and small [S] RNA segments : M1L2S2) has driven Brazil's largest and most geographically widespread OROV epidemic , expanding beyond the endemic Amazon basin to establish local transmission across multiple Brazilian states and other previously unaffected Latin American countries . The rapid spread of this lineage underscores its evolutionary potential and reinforces its significance as a public health threat .1 Similar to chikungunya and Zika viruses, expanding arboviruses can exhibit unexpected clinical and epidemiological shifts , including vertical transmissions , neuroinvasive effects, and potentially fatal outcomes.2–4 Although OROV typically causes self-limited febrile illness, accumulating clinical and experimental evidence suggests neurotropic potential .5 This Correspondence describes the first confirmed case of neuroinvasive OROV infection caused by the emergent M1L2S2 lineage in ext...

Stability of #influenza viruses in the #milk of #cows and #sheep

Abstract In late 2023, H5N1 high pathogenicity avian influenza (HPAIV) started circulating in dairy cattle in the USA . High viral titres were detected in milk from infected cows , raising concerns about onwards human infections . Although pasteurisation was shown to effectively inactivate influenza viruses in milk, unpasteurised milk still poses a risk of infection, both from occupational exposure in dairies and from the consumption of raw milk. We therefore assessed how long influenza viruses could remain infectious for in milk without heat inactivation. We examined the stability of a panel of influenza viruses in milk , including a contemporary H5N1 HPAIV and a variety of other influenza A and D viruses. We incubated viruses in cows' milk under laboratory conditions : at room temperature to simulate exposure in dairies and at 4°C to simulate exposure to refrigerated raw milk. Following an isolated report of H5N1 viral RNA being detected in milk from a sheep in the UK , we also c...

#Evidence of #Viremia in Dairy #Cows Naturally Infected with #Influenza A {#H5N1} Virus, #California, #USA

Abstract We confirmed influenza A virus (IAV) by PCR in serum from 18 cows on 3 affected dairy farms in California, USA . Our findings indicate the presence of viremia and might help explain IAV transmission dynamics and shedding patterns in cows. An understanding of those dynamics could enable development of IAV mitigation strategies.
