Researchers have recently found that diseases, mostly associated with Victorian times or underdeveloped nations, are making a comeback in modern countries. As per data, diseases like tuberculosis (TB), scarlet fever and scurvy are increasing at an alarming rate in neighborhoods across London.

According to CNN, these diseases were widespread in the 19th and early 20th centuries in neighborhoods across London. Sometimes, the cases even surpassed the fatality in areas like Iraq and Rwanda.

This sudden revival in the deadly disease might have been due to increased migration, malnutrition, poverty and inaccessible health care combined with lower vaccinations for whooping cough and the measles, CNN reported.

The UK Health and Social Care Information Centre found that malnutrition has increased by almost 51% over the past five years. “We meet families from across the U.K. struggling to put enough food on the table and, at the extreme end, you get people who are malnourished”, said Trussell Trust chairman Chris Mould, the NGO that coordinates food banks throughout the country.

As of now, the scurvy rate in the UK is 113 per 100,000 people, up by 33% from last year. Scarlet fever in the UK is also at all-time high. In 2014 alone, numbers of cases of scarlet fever were higher since 1960s.

TB has been recognized as a global threat, it has so far killed over 4,000 people daily, according to the 2015 Global Tuberculosis Report by the World Health Organization.
