The One Health vision in diarrheal disease in Africa

By João Mesquita, ICBAS and Ana Machado, ICBAS

Death from diarrhea in childhood is largely preventable. However, the impact of diarrhea remains high and not fully characterized due to the complex interaction between the environment, food, water and sanitation, highlighting the multiple visions of One Health, particularly in Africa. A significant proportion of cases can be prevented through vaccination, clean water, sanitation and hygiene. Despite this, data from recent years report that diarrhea is responsible for the death of around 90% of children under the age of five in sub-Saharan Africa. Due to the significant mortality and long-term negative impacts on growth and development associated with chronic diarrhea, reducing the global burden of diarrhea remains a priority requiring multisectoral interventions.

“Tide of plastic” on beaches in Northern Spain could affect Portugal

The researcher Bordalo e Sá considered today that the authorities must monitor the coast and “implement a tailor-made contingency plan” for the “plastic tide” on the beaches of Northern Spain that could affect Portugal.

“Right now the dominant currents are to the north. It is likely that these particles will reach Portugal in the spring, when the direction of the currents changes, and if the entire contents [of the containers that transported the plastic] have not washed up on the coast, which fell into the sea, although with a smaller impact. The first step will be to activate beach surveillance, also using civil society, and the second step will be to implement a tailor-made and supervised contingency plan”, explained the hydrobiologist from the University of Porto, speaking to Lusa.

Water, conflicts and refugees

By Adriano A. Bordalo e Sá, ICBAS and Joana Savva Bordalo e Sá, IPO-Porto

PORTO – Of all human rights, access to water is one of the most recent. It was declared by the UN General Assembly only in 2010. However, billions of people consume unsafe water worldwide, which causes diseases and eventually kills. Unfortunately, more than half a million children die from diarrhea due to the consumption of unsafe water every year.

During conflicts and war, life gets worse. The recent invasion of the Gaza strip, is yet another painful example alongside the conflicts in Eastern Europe, Yemen, Burma, Sudan, Somalia, Ethiopia, D. R. Congo, among others. Without water there is no rehydration, no hygiene, no health. In malnourished Palestine, infectious diseases are spreading and in Yemen, the cholera epidemic – a waterborne disease – has remained uncontrolled since 2016, having affected nearly 3 million people, especially children.

In the middle of last year, there were 110 million displaced people worldwide, of which a third were refugees, something never seen before. If in the rich parts of Algarve or California every person uses 1,000 liters of water per day (120 in Portugal), the refugees, at most, have 5 liters (half a bucket) available, often filthy, making their lives even more miserable, compromising future generations.

One Health Talks

To face the challenge of discussing One Health in less than 60 minutes, we continued the 1st cycle of monthly ICBAS talks on January 18.

In the fourth session, António Araújo, guest Full Professor and Director of the Integrated Masters in Medicine at ICBAS, invites Joana Simões, Medical Oncology Assistant at the Centro Hospitalar Universitário de Santo António, to discuss the topic ‘The impact of hormones on the development of cancer', within the scope of the One Health.

The event will take place from 1pm-1.50pm in monobloc 4 of ICBAS.
