Yaoundé, May 30, 2019 (AFP) - Cameroon has declared a public emergency after reporting a polio case in its far north, four years after the virus disappeared from the country, the health ministry said on Thursday.   The confirmed case of polio type 2 was found in the Mada area in the remote north bordering Chad and Nigeria, the ministry said in a statement.   It declared a "new polio epidemic following the confirmation of a case of poliovirus type 2 detected in samples."

A source at the ministry said the outbreak may have been caused in part by a refusal of vaccinations and the cross-border movement of people in the area.   Polio is a highly infectious viral disease which mainly affects young children and can result in permanent paralysis. There is no cure and it can only be prevented through immunisation.   International polio vaccination efforts have run into problems in Pakistan and Afghanistan. Militants and religious leaders in rural areas often tell locals immunisation is part of a shadowy conspiracy to weaken their faith.

Yaoundé, Nov 28, 2018 (AFP) - At least 29 people were wounded Wednesday when a women bomber blew herself up in a border town in Cameroon's Far North, a region frequently hit by Boko Haram jihadists, security sources said.    But a second bomber was shot dead by troops deployed in the town before she could detonate her explosives, the source said.    "A suicide bomber blew herself up this morning in Amchide" on the Nigerian border, a regional security source said, speaking on condition of anonymity and giving a toll of 29 wounded.

The attack occurred on market day when the town was filling up with early-morning shoppers, a local civil defence group official said.    "There were many people hurt, I saw about 20," he said. "After the attack, the market emptied."   A once-bustling trade hub, in 2014 Amchide was thrust into the forefront of a major battle between Cameroonian troops and Boko Haram militants who held the nearby Nigerian town of Banki for several months.    The violence forced most residents to flee the town, although some have now begun to return.    After pushing back Boko Haram, the Cameroonian army dug long trenches around Amchide and even inside the town to foil new incursions by the jihadists, with Wednesday's attack the first in many months.

Wanji S, Chounna Ndongmo WP, Fombad FF, et al. Impact of repeated annual community-directed treatment with ivermectin on loiasis parasitological indicators in Cameroon: implications for onchocerciasis and lymphatic filariasis elimination in areas co-endemic with _Loa loa_ in Africa.

Abstract
---------
Background
Loiasis is a filarial infection endemic in the rainforest zone of west and central Africa, particularly in Cameroon, Gabon, Republic of Congo, and Democratic Republic of the Congo. Repeated treatments with ivermectin have been delivered using the annual community-directed treatment with ivermectin (CDTI) approach for several years to control onchocerciasis in some _Loa loa_ and _Onchocerca volvulus_ co-endemic areas. The impact of CDTI on loiasis parasitological indicators is not known. Therefore, we designed this cross-sectional study to explore the effects of several rounds of CDTI on parasitological indicators of loiasis.

Methodology/principal findings
The study was conducted in the East, Northwest, and Southwest 2 CDTI projects of Cameroon. Individuals who consented to participate were interviewed for ivermectin treatment history and enrolled for parasitological screening using thick smears. Ivermectin treatment history was correlated with loiasis prevalence/intensity. A total of 3684 individuals were recruited from 36 communities of the 3 CDTI projects, and 900 individuals were from 9 villages in a non-CDTI district. In the East, loiasis prevalence was 29.3% (range, 24.2% to 34.6%) in the non-CDTI district but 16.0% (3.3% to 26.6%) in the CDTI district with 10 ivermectin rounds (there were no baseline data for the latter).

In the Northwest and Southwest 2 districts, reductions from 30.5% to 17.9% (after 9 ivermectin rounds) and from 8.1% to 7.8% (not significantly different after 14 rounds) were registered post-CDTI, respectively. Similar trends in infection intensity were observed in all sites. There was a negative relationship between adherence to ivermectin treatment and prevalence/intensity of infection in all sites. None of the children (ages 10 to 14 years) examined in the East CDTI project harboured high (8000 to 30,000 mf/mL) or very high (more than 30,000 mf/mL) microfilarial loads. Individuals who had taken more than 5 ivermectin treatments were 2.1 times more likely to present with no microfilaraemia than those with fewer treatments.

Conclusion
In areas where onchocerciasis and loiasis are co-endemic, CDTI reduces the number of and microfilaraemia in _L. loa_-infected individuals, and this, in turn, will help to prevent non-neurological and neurological complications post-ivermectin treatment among CDTI adherents.
====================
[Onchocerciasis (African River blindness) is a neglected tropical disease, but the invasive nematode _Loa loa_ is not on the list. The study clearly demonstrates that scheduled regular ivermectin against onchocerciasis also reduced the nematode burden of _L. loa_.

_L. loa_, the African eye worm, is a nematode transmitted by tabanid flies (Order: Diptera; Family: Tabanidae) of the genus _Chrysops_. _L. loa_ may cause skin oedema (Calabar swellings) and may occasionally invade the eye. As far as it is known, there is no animal reservoir. - ProMED Mod.EP]

Buea, Cameroon, Oct 6, 2018 (AFP) - "For the peak season I would have about 280 persons climbing Mount Cameroon," said John Ngomba, a tour guide in the town of Buea, which has been at the forefront of Cameroon's anglophone separatist insurgency.   "But now there are no tourists coming. It's really crazy. The reason tourists are not coming is because of the crisis."

Since an independence declaration a year ago, Buea -- once a tourist hotspot -- has suffered near-daily clashes and visitors have all but disappeared.   The violence has claimed the lives of at least 420 civilians, 175 members of the security forces and an unknown number of separatists, according to the International Crisis Group think-tank.   "Sometimes I would receive 600 Germans a year. They would come through the cruise ships. I could have about 30 to 50 tourists a week who came to visit," said Ngomba in his hut in the town's Bismarck Fountain gardens.

Cameroon was once a German colony but was divided between Britain and France after World War I -- a separation that lies at the heart of the current conflict.   France's colony won independence in 1960, becoming Cameroon, and in 1961 the British-ruled Southern Cameroons was merged into it, giving the new state English-speaking majorities in the northwest and southwest.   "I am a father of five children. How am I living with them? It's impossible," said Ngomba, who has appealed for help from the German embassy, which assists with the upkeep of the garden containing a bust of Bismarck.

- Empty hotels -
"The fountain is not even working," he said, looking out over the restive town below and the former German governor's residence, which is now an army base.   But Ngomba insisted that the foothills above Buea remained safe.   "If the tourists arrive and get to this point, they are safe," he said.   "I tell people: after the election, things will be OK," he added of polls due on unday at which President Paul Biya will seek a seventh term.

But several countries including Germany, Britain, Canada and the United States have issued security advisories to their citizens about the anglophone regions.   "We used to have customers coming from many countries -- America, Europe, Nigeria," said Janet Nkowo, 30, a receptionist at the Eta Palace Hotel in downtown Buea.   "I think it's because of the crisis. The difference is really clear," she said.   "We have one-quarter of what we had, I don't know how the director does it. I think things will hopefully get better on Sunday."

Most of Buea's hotels are sitting empty, the majority of shops are shuttered and only a handful of students queued up at the town's university to register for the new academic term.   A total of 246,000 people have fled their homes in the southwest region that includes Buea -- and 25,000 have left the country altogether for Nigeria, according to UN figures.

At the town's weekly market, one of the few retail outlets still functioning, many stalls sat empty.   A man in a white vest shouted "French bastards" at passers-by, in French.   "Maybe if voting passes well, they will come back," said Fidelis Kum, a stallholder selling hair extensions, as customers haggled over live chickens nearby and women sat shelling snails.

The health ministry said 6 people have died in Cameroon from a cholera outbreak that has infected 43 people since May 2018. "Cases of cholera were documented since May 2018 in 4 districts in northern regions," health minister Andre Mama Fouda said in a statement sent late [Sat 14 Jul 2018]. He said one case of the disease had been found in the capital Yaounde. "From the moment the 1st cases were documented in the northern region, every measure was taken to contain the epidemic," Fouda said.

Cholera is caused by a bacterium transmitted through contaminated food or drinking water. It causes acute diarrhoea, with children particularly at risk. In 2010, an outbreak of the disease killed more than 750 people across Cameroon.
