By Naveen Athrappully Contributing Writer  Monkeypox cases in African countries have seen a massive jump, with nations in Central Africa accounting for more than eight out of 10 infections, according to the Africa Centers for Disease Control and Prevention.  Since January, a total of 48,093 cases of monkeypox, known as mpox, were reported from 19 member states of the African Union, with 10,372 confirmed infections and 1,048 deaths, the agency said in an Oct. 31 news briefing.  The number of confirmed cases so far this year is up by more than 500% compared to the entirety of 2023.  Central Africa — Burundi, Chad, Equatorial Guinea, Gabon, Cameroon, the Central African Republic, the Democratic Republic of the Congo, the Republic of the Congo, and São Tomé and Príncipe — accounted for more than 85% of cases and more than 99% of deaths.  The greatest number of confirmed cases have been reported in the Democratic Republic of the Congo.  Five countries have not reported a confirmed case in the past five weeks — Cameroon, Gabon, Guinea, Rwanda, and South Africa. Cases in Liberia and Uganda have increased.  Uganda reported its first death from confirmed cases in late October. Adding in an earlier death in Kenya, only two people have died in Africa from mpox outside of Central Africa so far this year.  Mpox has two genetic clades — 1 and 2. Experts point out that clade 1 causes more severe cases while also spreading with greater ease, thereby posing higher health risks.  The Africa CDC reported on two subclades of clade 1 — a and b. Children younger than age 15 are “disproportionately affected” by clade 1a, making up nearly 66% of sampled sequences.  The agency noted that 53% of clade 1b cases were among individuals ages 15 and older, which suggests “intimate and close contacts as major transmission routes.”  Vaccination plans are in place targeting six nations — Democratic Republic of the Congo, Nigeria, Rwanda, the Central African Republic, South Africa, and Cote d’Ivoire.  The agency called for intensifying efforts in active surveillance, universal testing, targeted vaccination, and holistic case management to deal with the increasing mpox cases.  “Political and financial support is critical to control the current outbreak and prevent a sexually transmitted pandemic more severe than COVID-19,” the Africa CDC stated.  Global Spread of Mpox  Meanwhile, the World Health Organization activated its Global Health Emergency Corps in October for the first time to provide support to nations with mpox outbreaks. Set up in 2023, the corps is a collaboration platform for nations and health emergency networks.  “WHO and partners are supporting the government of the Democratic Republic of the Congo and other countries to implement an integrated approach to case detection, contact tracing, targeted vaccination, clinical and home care, infection prevention and control, community engagement and mobilization, and specialized logistical support,” said Dr. Mike Ryan, executive director of WHO’s Health Emergencies Program.  Last month, the WHO approved the first mpox diagnostic test for emergency use, which enables the detection of both clade 1 and 2 variants of the virus from swabs of human skin lesions.  Dr. Yukiko Nakatani, WHO assistant director-general for access to medicines and health products, said the new diagnostic test is a “significant milestone” in ensuring that testing for the virus expands in affected nations.  “Increasing access to quality-assured medical products is central to our efforts in assisting countries to contain the spread of the virus and protect their people, especially in underserved regions,” Nakatani said.  As of Oct. 20, most countries outside of Africa have detected only clade 2b of mpox, according to a WHO report.  The exceptions to this trend are Sweden, Thailand and Germany, which have detected one case each of clade 1b among travelers from Africa. India also identified a clade 1b case in a traveler from the United Arab Emirates. In Africa, all viral clades of monkeypox have been reported, according to the report.  As for the United States, “there have been no reported cases of clade I mpox” in the country, an Oct. 23 update from the U.S. Centers for Disease Control and Prevention stated. “Clade II mpox is still circulating at low levels.”  Many cases in regions with regular monkeypox outbreaks were identified in children, raising concerns as to whether minors in the United States could be affected if the disease were to spread significantly in the country.  However, the CDC does not expect to see such risks. The agency ran a simulation of clade 1 outbreaks occurring in the United States, with the modeling also looking at impacts on children.  “The results indicate that close-contact transmission within and between households is unlikely to result in a large number of mpox clade I cases in the United States,” the agency stated.  The post Mpox cases spike 500% in Africa   appeared first on Santa Clarita Valley Signal.
