On 27 April, the WHO reported 151 cases of salmonellosis in 11 countries, caused by the consumption of 'kinder eggs' or other contaminated products of the same brand. In Spain, two cases have been confirmed.

Climate change will lead to at least 15,000 new cross-species virus transmissions by 2070, as habitat shifts on a 2°C warmer planet will bring previously distant animals closer together. This result, published in Nature, points to increased exposure of humans to pathogens from wild animals.

In recent weeks, several countries have detected unusually severe cases of hepatitis of unknown origin in healthy children. Some of the patients have required transplantation and at least one of them has died. Researchers are working on several hypotheses around an adenovirus, but the matter is still shrouded in uncertainty.

Whole genome analysis of more than 12,000 tumors has identified new patterns of mutations associated with specific cancers. These combinations generate specific mutational signatures, the study of which provides information on environmental factors causing the mutations. The work is published in Science.

A study based on observations of the Greenland ice sheet, published in Nature Communications, suggests that there may be shallow liquid water on Jupiter's moon Europa. The finding could provide insights into the geophysical processes that formed the moon.

Recent research published by researchers of Carlos III University of Madrid shows that individuals perceive less COVID-19 infection risk and engage in less health-protective behaviors when they associate the risk with close friends – a phenomenon labeled as the “friend-shield effect”.

This week the European Centre for Disease Control and Prevention (ECDC) has warned of an increase in cases of hepatitis of unknown origin in children in the UK. Three cases have been diagnosed in Ciudad Real, Madrid and Aragon, one of which required a liver transplant. With the current information it is difficult to establish the cause.
