The World Health Organization (WHO) has reached out to 16 African nations to provide support for preparedness and response to a listeriosis outbreak that started in South Africa in 2017 but is now threatening other countries on the continent.
The 16 countries are Angola, Botswana, the Democratic Republic of the Congo, Ghana, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namibia, Nigeria, Swaziland, Tanzania, Uganda, Zambia and Zimbabwe.
Nearly 200 South Africans have died since January 2017 as a result of contaminated ready-to-eat meat products that are widely consumed in South Africa and may also have been exported to two West African countries and 14 members of the South African Development Community (SADC)
South African health authorities recently declared the source of the outbreak as a factory in Polokwane, South Africa. This prompted a national and international recall of the food products. However, in light of the potentially long incubation period of listeriosis and the challenges relating to large scale nationwide recall processes, further cases are likely to occur.
Namibia has reported one confirmed case of listeriosis, a man who was admitted to hospital in early March. An investigation is ongoing to determine whether the case is connected to the outbreak in South Africa.
WHO’s Health Emergencies programme, the Global Outbreak alert and Response Network (GOARN) and the International Food Safety Authorities Network (INFOSAN) are working with the 16 priority countries to improve their ability to prepare for, detect and respond to potential outbreaks.
Immediate steps will include increasing awareness on listeriosis, enhancing active surveillance and laboratory diagnosis, ensuring readiness of Rapid Response Teams, and strengthening coordination and contingency planning. Experts have been deployed to South Africa, Lesotho and Swaziland to support these efforts.
“This outbreak is a wake up call for countries in the region to strengthen their national food safety and disease surveillance systems,” says Dr Matshidiso Moeti, WHO Regional Director for Africa.
The Ministry of Health in Uganda in mid-March, 2018 warned Ugandans against consuming imported meat products mainly imported from South Africa in a bid to avoid the spread of the disease to the Country. No case of Listeriosis has been reported in Uganda as of 22nd March, 2018.
The link between the contaminated products, the producing company and strains of Listeria isolated from the patients was made by the use of whole genome sequencing of isolated strains of the Listeria bacteria. WHO is supporting further genome sequencing to determine which cases are linked to this on-going outbreak.
In March, South Africa hosted a meeting of SADC health ministers to address regional preparedness and response to listeriosis. Ministers committed to regional collaboration, exchanging information and strengthening national food safety systems in line with international standards.
WHO does not currently recommend any trade related measures in relation to the current outbreak of listeriosis in South Africa, other than the recall of products identified as sources of infection.
Countries are encouraged to pay more attention to common foodborne pathogens such as Salmonella, Campylobacter, E.coli and Listeria, to notify WHO of listeriosis outbreaks in line with the International Health Regulations (2005), and to make use of WHO guidelines to strengthen surveillance of and response to the foodborne disease.
- Listeriosis is an infectious disease caused by the bacterium Listeria monocytogenes.
- Listeria monocytogenesare widely distributed in nature. They can be found in soil, water, vegetation and the faeces of some animals and can contaminate foods.
- High risk foods include deli meat and ready-to-eat meat products (such as cooked, cured and/or fermented meats and sausages), soft cheeses and cold smoked fishery products.
- Pregnant women, the elderly or individuals with a weakened immune system, such as people with immuno-compromised status due to HIV/AIDS, leukaemia, cancer, kidney transplant and steroid therapy, are at greatest risk of severe listeriosis and should avoid high risk foods.
- Listeriosis is a serious, but preventable and treatable disease.

Traditionally, rainfall was celebrated because it is believed to be a blessing from the creator. For farmers, it should be celebrated much more since over 85 percent of farmers in Uganda depend on it for agriculture. Even in urban areas, rainfall would mean life to urban farms and gardens, more rain water – hence a saving on the water bills and much more.
However, the situation has over the years been changing from good to bad and now it is worse. Rain is now more cursed than cherished in both urban and rural areas. What a pity!
A modern saying in Uganda goes that ‘Water is life when you are not staying in Bwaise’. Bwaise is one of the suburbs of Uganda’s Capital City- Kampala that is prone to floods.
What used to be a Bwaise problem however is now in many other urban areas.
In March 2018 alone- Mbarara, Rukiga (Muhanga town) and Kabale towns among others saw the worst floods in their recent past and this is a sign of what has gone wrong over the years and what is likely to come.
In rural Uganda, the writing has for long been over the wall. The rate of environmental degradation has been growing to alarming levels presently. Hill slope forest cover has been decreasing daily, the hill slopes are poorly cultivated, bush burning has persisted while the wetlands in the low lying areas have been encroached on for agricultural practices- making mudslides, soil erosion and subsequent flooding inevitable. These floods for many years have been far in rural areas, away from the public limelight and wide mass media coverage.
However, now that the ‘flood spirits’ have invaded the urban areas, where mass media coverage is high, it is now time to wake up to the mess that has befallen our areas.
Much talk has for years centred on the rate of environmental degradation in rural areas but this phenomenon is real in urban areas. The biggest portion of wetlands in urban areas have been degraded mainly for human settlement and many forests have been degazetted. This is dangerous for our urban areas. To make matters worse, our urban areas have no adequate planning for drainage channels as well poorly planned human settlements.
In many of the big urban areas, the damage has already been done and little can be done to lessen the flooding cases- but still something can be done and must be done immediately. All buildings should have a rain water harvesting system or plan in place. This would ultimately lessen the amount of water from the roofs to the surface. Also, urban drainage channels must be opened and maintained. We cannot afford a situation where rain water finds its way to wherever it wants. Our urban areas must have more trees planted and more green belts while all buildings must be on plan and the approval of such plans must be based on technical guidance not corrupt tendencies. For the growing towns, this is the time to have the necessary plans in place to mitigate future problems like this. If such floods are not lessened, loss of lives, destruction of infrastructure, disruption of transport and business as well as spread of water-borne diseases will continue in Uganda.
In a nutshell, urban and rural floods are a sign of something gone wrong. We must take them as a warning of more danger to come and a springboard to action. In Uganda, we are found of calling government to act but in this case, government alone cannot do much. We all must join hands to protect the environment and promote sustainable urban growth.
Survival rates for children who get kidney transplants have improved significantly over the last half-century, a new study finds.
“The outlook for infants and children with end-stage kidney disease was once dismal, with poor survival rates after transplant. There has been great progress in pediatric kidney transplantation, and now the patient survival rate is almost 100 percent,” said the study’s principal investigator, Dr. Srinath Chinnakotla.
Chinnakotla is an associate professor of surgery at the University of Minnesota Masonic Children’s Hospital in Minneapolis, where the study was done.
Since 2002, 97 percent of children who had kidney transplants at the hospital were alive a year later. That compares to 85 percent 40 to 50 years ago, the study showed. Read More..
This is absolutely good news and light at the end of the tunnel. With this break-through, more children will survive kidney transplant and this is a strong foundation for further improvements in the entire health system. However, as we celebrate this good news, it is equally important to think about thousands if not millions of disadvantaged children who desperately need a kidney transplant but cannot be saved either because of the poor economic nature of their families or lack of such services in major health facilities nearby.

Blood pressure and fluid retention improve in those counseled by dietitians, small study shows
Encouraging people with kidney disease to reduce their salt intake may help improve blood pressure and cut excess fluid retention, at least for a while, a new study suggests.
Study participants lowered their systolic blood pressure (the top number)
by almost 11 points, on average, on a salt-restricted diet versus their usual diet. They also flushed out a liter of water (about one-quart) from their bodies, on average, by slashing salt in their diets, researchers said.
Having high blood pressure and retaining excess salt and water in the body stresses the heart and blood vessels, explained lead author Dr. Rajiv Saran of the University of Michigan.
For kidney disease patients, high blood pressure (or “hypertension”) and excess fluid in the body can be a toxic combination. “They die predominantly of cardiovascular disease,” said Saran, a professor of internal medicine and epidemiology in the nephrology division.
Yet doctors rarely have time or make time to counsel each patient about salt-restricted diets, he said.
Saran and co-investigators wondered whether having trained dietitians talk to patients with chronic kidney disease by phone or in person about ways to lower daily sodium intake would make a difference. Read More
Low back pain affects millions of people in the United States, and the condition is one of the most common reasons for people missing work. New guidelines from the American College of Physicians recommend noninvasive ways of treating nonradicular low back pain.
The American Chiropractic Association (ACA)
report that approximately 31 million U.S. individuals experience low back pain at one point during their lives. The ACA also note that low back pain is the leading cause of disability across the world, as well as one of the most popular reasons why people miss work.
The condition accounts for a large proportion of all doctor visits in the U.S., and almost 25 percent of the entire adult population in the U.S. has experienced at least one day of low back pain in the past 3 months.
The fight against Polio has been boosted by a new grant from Rotary International- the largest group of committed volunteering men and women committed to serve and change the world.
Rotary has announced $35 million in grants to support the global effort to end polio, bringing the humanitarian service organization’s contribution to $140 million since January 2016.
Nearly half of the funds Rotary announced January 2017 ($16.15 million) will support the emergency response campaigns in Nigeria and the Lake Chad Basin (Chad, northern Cameroon, southern Niger and Central African Republic). Four cases of polio were detected in Nigeria in 2016, which had previously not seen a case since July 2014.
With these cases, funding is needed to support rapid response plans in Nigeria and surrounding countries to stop the outbreak.
While significant strides have been made against the paralyzing disease, with just 35 cases reported in 2016, polio remains a threat in hard-to-reach and underserved areas, and conflict zones. To sustain this progress, and protect all children from polio, experts say $1.5 billion is needed.
In addition to supporting the response in the Lake Chad Basin region, funding has been allocated to support polio eradication efforts in Afghanistan ($7.15 million), Pakistan ($4.2 million), Somalia ($4.64 million), and South Sudan ($2.19 million). A final grant in the amount of $666,845 will support technical assistance in UNICEF’s West and Central Africa Regional Office.
Rotary has contributed more than $1.6 billion, including matching funds from the Bill and Melinda Gates Foundation, and countless volunteer hours since launching its polio immunization program, PolioPlus, in 1985. In 1988, Rotary became a spearheading partner in the Global Polio Eradication Initiative with the World Health Organization (WHO), UNICEF, U.S. Centers for Disease Control and Prevention, and was later joined by the Bill & Melinda Gates Foundation. Since the initiative launched, the incidence of polio has plummeted by more than 99.9 percent, from about 350,000 cases a year to 35 confirmed in 2016, and no cases in 2017 so far.
What is Polio?
According to the World Health Organization (WHO), Poliomyelitis (polio) is a highly infectious viral disease, which mainly affects young children.
The virus is transmitted by person-to-person spread mainly through the faecal-oral route or, less frequently, by a common vehicle (e.g. contaminated water or food) and multiplies in the intestine, from where it can invade the nervous system and can cause paralysis.
Initial symptoms of polio include fever, fatigue, headache, vomiting, stiffness in the neck, and pain in the limbs. In a small proportion of cases, the disease causes paralysis, which is often permanent. There is no cure for polio, it can only be prevented by immunization.
Key Facts about Polio
- Polio (poliomyelitis) mainly affects children under 5 years of age.
- 1 in 200 infections leads to irreversible paralysis. Among those paralysed, 5% to 10% die when their breathing muscles become immobilized.
- Polio cases have decreased by over 99% since 1988, from an estimated 350 000 cases then, to 74 reported cases in 2015. The reduction is the result of the global effort to eradicate the disease.
- As long as a single child remains infected, children in all countries are at risk of contracting polio. Failure to eradicate polio from these last remaining strongholds could result in as many as 200,000 new cases every year, within 10 years, all over the world.
- In most countries, the global effort has expanded capacities to tackle other infectious diseases by building effective surveillance and immunization systems
Rotary brings together a global network of volunteer leaders dedicated to tackling the world’s most pressing humanitarian challenges. Rotary connects over 1.2 million members of more than 35,000 Rotary clubs in over 200 countries and geographical areas.
The mosquito, Aedes aegypti, is causing widespread fear in Brazil where it is spreading the Zika virus that has been linked to thousands of babies being born with birth defects.
So what do we know about it?
It loves our cities
This is not some jungle-dwelling insect that rarely comes into contact with people.
It is one of those animals, like cockroaches, pigeons and urban foxes, that thrives in built-up areas.
It does not need natural water sources to breed as it can lay eggs in the small and plentiful pools of stagnant water, such as gutters or flower pots, found in cities . Read more
