A very important patent decision may have just been made in Mumbai. Abbott Laboratories, one of the world's biggest research-based drug companies, doesn't like it - they are now considering what to do. But HIV/Aids campaigners are celebrating. The Mumbai patent office has rejected Abbott's application for a patent in India on its drug Kaletra - a combination of the two antiretroviral medicines lopinavir and ritonavir. The decision could help enable the manufacture of cheap versions of a key Aids drug, reports the London Guardian.

Sex workers operating in East Africa are generally aware of the HIV risks of unprotected sex, but for many of them, the extra cash incentive clients often offer for sex without a condom is worth the risk. According to Basilisa Ndayisaba, coordinator of local NGO Society for Women against AIDS in Africa (SWAA-Burundi), which raises awareness among sex workers on condom use and HIV risk, despite their best efforts, many sex workers in Bujumbura remain apathetic about condom use.

The Ethiopian government has unveiled an HIV policy for its transport sector, which has grown significantly in recent years alongside the rapidly expanding road network. 'Various national studies have shown that those working across the transport sector - especially drivers and their assistants - are vulnerable to HIV infection as they spend considerable time away from their families,' said Ethiopia's transport authority director Kassahun Hailemariam.

Despite some progress, Nigeria is lagging behind its peers in reducing deaths among children under five. The mortality rate remains worryingly high for newborn infants – 700 children less than 28 days old die in the country every day. A new report published by Nigeria’s Ministry of Health however acknowledges that the mortality rate for children has fallen by about a fifth since 1990, but this progress has been unevenly spread – with important implications for health policy.

The exact number of women and girls who have experienced sexual abuse in the DRC is not known, writes Nikki Whaites for the Gender Links Opinion and Commentary Service. In 2008, the United Nations Population Fund reported 15,996 registered cases of sexual violence across the country. And 65 per cent of those were children, the majority girls – 10 per cent were under the age of 10. But few are paying attention.

The World Health Organisation launched a plan on Wednesday to stop a form of drug-resistant malaria from spreading from Southeast Asia to Africa, where millions of lives could be at risk. It would cost about $175 million a year to contain and prevent the global spread of the artemisinin-resistant parasite which first emerged along the Thai-Cambodian border in 2007, the United Nations agency said.

With barely months to go before the second India-Africa Forum Summit, India has said the Indian model of 'green revolution' had an appeal for African countries across the board and underlined that boosting agriculture and food security were at the heart of its engagement with the 53-nation African continent. 'Agriculture is without doubt at the forefront of India's engagement with Africa in the current transformation phase,' Gurjit Singh, joint secretary in charge of east and southern Africa, told experts at a seminar on exploring twin themes of food security and India-Africa relations in the context of South-South cooperation.

At an increased risk of HIV and often unable to negotiate safe sex with clients, sex workers have been a major focus in HIV prevention and treatment. However, away from the streets and brothels, their children have been largely ignored. Now a small but growing body of research has suggested that the children of sex workers face a range of HIV risks including early sexual debut, low school enrolment, parental abandonment and psychological issues, including social marginalisation, related to their mothers' work, according to Jennifer Beard, assistant Professor in the Department of International Health at the Boston University School of Public Health.

Using panel data from Mozambique collected in 2007 and 2008, the authors of this working paper explore the impact of the food crisis on welfare of households living with HIV/AIDS. The analysis finds that there has been a real deterioration of welfare in terms of income, food consumption, and nutritional status in Mozambique between 2007 and 2008, among both HIV and comparison households.

An unusually deadly outbreak of poliomyelitis (polio) in Congo has scientists scratching their heads. Close to 500 people were left paralysed and almost 200 succumbed to polio since the outbreak began in October. The viral disease killed around 42 per cent of people infected, unlike typical outbreaks that kill 5–10 per cent. And although the disease usually attacks children under five years of age, most victims in this outbreak were men aged between 15 and 25 years.

Rats that can smell the tuberculosis (TB) bacterium in a sputum sample could be more effective in detecting TB than expensive laboratory tests, a study suggests. The Gambian pouched rat (Cricetomys gambianus), found all over Sub-Saharan Africa, can smell the difference between TB bacteria and other germs found in human phlegm, according to researchers writing in The American Journal of Tropical Medicine and Hygiene last month (December).

The International Women's Media Foundation (IWMF) is offering 10 journalists fellowships to produce investigative reports on the HIV/AIDS epidemic in South Africa. The project will offer 10 experienced South African reporters one-on-one coaching with media trainers and stipends to conduct interviews and in-depth research.

Widespread unrest continued to rock Algeria on Sunday (9 January) as protests continued against rising food prices despite government action to stem the riots. The Algerian cabinet agreed on Saturday to lower the custom duties and taxes on sugar and other food stuffs by 41 per cent as a temporary act to cut prices. But the measure, which will last through the end of August, did not end days of conflict in the streets between angry youth and security services.

Food riots, geopolitical tensions, global inflation and increasing hunger among the planet's poorest people are the likely effects of a new surge in world food prices, which have hit an all-time high according to the United Nations. London's Independent newspaper reports that the UN's index of food prices – an international basket comprising wheat, corn, dairy produce, meat and sugar – stands at its highest since the index started in 1990, surpassing even the peaks seen during the 2008 food crisis, which prompted civil disturbances from Mexico to Indonesia.

Unrest following Côte d'Ivoire's presidential election is blocking a nationwide vaccination drive against yellow fever, a fatal mosquito-borne disease that is affecting people throughout the country. In the past month 11 people have died in the centre-north departments of Séguéla, Katiola, and Béoumi; two cases of yellow fever have been confirmed and there are a further 21 suspected cases in those departments and in nearby Mankono, according to local health workers and the World Health Organisation (WHO).

In Zambia, a silver lining has emerged for widespread rural hunger and poverty, thanks to homegrown agricultural research. Local scientists have successfully developed four new, early-maturing and high- yielding cassava cultivars in an ambitious research project conducted in the cassava-rich Luapula Province, under the on-going Root and Tuber Improvement Programme (RTIP).

For those who walked the walk
Even to the graves of those who fell
Those who held out…

Medical experts have warned that malaria and HIV have monopolised interventions geared towards curbing child mortality in Kenya, thus ignoring the equally deadly killer, diarrhoea. This disease has silently claimed the lives of hundreds of children every year. Cecilia Njambi, a mother of two, lost her first-born son to diarrhoea. 'He hadn’t slept well the previous night and had complained that his tummy hurt. His stool was loose but we weren’t alarmed as no one takes diarrhoea seriously anyway. We just assumed that he must have eaten something that didn’t go down well with him.'

According to Vision 2030, which is a government strategic plan on how to boost growth and development in Kenya, there are an estimated five million out of an estimated eight million households who depend directly on agriculture, despite the fact that agriculture continues to be one of the most under-budgeted ministries. Researchers have intensified research on crops that can grow in most parts of the country and which can be used to alleviate food insecurity. This has led many Kenyans to accommodate traditional vegetables that were earlier dismissed as the 'poor man’s crop'.

After successfully suppressing scourges of fruit, tsetse and screwworm flies in the Americas, researchers are exploring whether the same sterilised insect technique can be used to control malaria, which kills some one million people every year, many of them in Africa. Entomologists and other researchers at the International Atomic Energy Agency (IAEA) are testing whether sterilised insect technique (SIT) can be used to reduce populations of malarial mosquitoes. Experiments are taking place at the agency’s laboratory facilities in eastern Austria, and researchers emphasise that their work is at an early stage.
