Information for travellers visiting Zika affected countries

Based on available evidence, WHO has issued no general restrictions on travel or trade with countries, areas and/or territories with Zika virus transmission.

However, WHO is advising pregnant women not to travel to areas with ongoing Zika virus oubreaks. This advice is based on the increased risk of microcephaly and other congenital malformations in babies born to pregnant women infected with Zika virus. Microcephaly is a condition where a baby is born with a small head or the head stops growing after birth.

Could artificial sweeteners make people more hungry?

Artificial sweeteners can boost appetite by activating hunger pathways in the body, scientists have found in animals.

In fruit flies and mice, the mismatch between sweet taste and fewer calories sends the body into “feed me” mode, the journal Cell Metabolism reports.

But UK nutritionists say this does not mean the same is true in humans.

They say low calorie sweetened foods can help people keep weight off and are better for our teeth than sugar.

The researchers, however, say more work is needed to make sure that the billions of people who regularly consume sugar substitutes don’t have the same reaction as they saw in their animal tests.

Viral hepatitis ‘kills as many as Aids or TB’

Viral hepatitis is one of the leading killers across the globe, with a death toll that matches Aids or tuberculosis, research in the Lancet suggests.

The report estimates that hepatitis infections and their complications led to 1.45m deaths in 2013 – despite the existence of vaccines and treatments.

World Health Organization data shows there were 1.2m Aids-related deaths in 2014, while TB led to 1.5m deaths.

The WHO has put forward a global strategy to tackle hepatitis.
