Annual Data 2011

Information relating to notifications of infectious diseases for 2011 are summarised as key points with more detailed tables and charts below. These tables and charts contain 2011 and previous years data for notifications of infectious disease.

These analyses are for confirmed notifications to the year ended 31 December 2011. 

Key Points


The three cases of botulism notified in 2011 were also confirmed microbiologically. All three cases were siblings in the same family who consumed a jar of Korma sauce. The source of contamination of the jar was unknown. The report of the Incident Management Team is available on the HPS website.


Notifications for measles are on the basis of clinical suspicion. As measles has become rare in Scotland, due to high uptake of vaccination, it is difficult to diagnose clinically without laboratory tests. There were 82 measles notifications in 2011 and 24 laboratory confirmed cases. This compares with 93 notifications and 11 laboratory confirmed cases in 2010. The majority of measles cases and suspected cases continue to occur in unimmunised or under-immunised individuals.

Meningococcal infection

There were 103 cases of meningococcal infection notified in 2011, compared to 93 in 2010. Despite the small increase in 2011 compared to 2010, the overall trend has been a decline since the introduction of the Meningococcal C (MenC) vaccine in 1999, when 329 cases were notified. More than half the cases notified in 2011 (61%; 63 cases) were in children aged under 15 years.


In 2011 there were 607 notifications of mumps compared with 727 notifications in 2010 and 1129 in 2009. Cases continue to be mainly among the young adult age group, aged 15 to 24, who are often under-immunised against mumps, as they were not routinely offered two doses of MMR vaccine as children.

Necrotising fasciitis

There are several organisms which are associated with the development of the clinical condition necrotising fasciitis. This clinical condition only became notifiable in Scotland in January 2010. Awareness amongst clinicians of the need to report this condition was still increasing in 2010/11. Laboratory detections of invasive disease from one of the key organisms associated with the infection, Group A Streptococcus, did not show an increase during the period of observation. It is therefore uncertain whether the increase in clinical reports observed in 2010/11 represents a real increase in the clinical condition or increased reporting resulting from raised awareness amongst clinicians.

Pertussis (whooping cough)

There were 85 notifications of pertussis in 2011 compared to 45 in 2010. Although the number of notifications in 2011 was an increase of 88% compared to 2010, the notifications in 2011 were less than those reported in 2007, 2008 and 2009 (98, 134 and 104 respectively).


Notifications for rubella are on the basis of clinical suspicion. As rubella has become rare in Scotland, it is difficult to diagnose clinically without laboratory tests. There were 20 notifications of rubella in 2011, and no laboratory confirmed cases. This compares with 39 notifications and one laboratory confirmed cases in 2010.


There were 457 notifications of tuberculosis in 2011. This was a decrease of 12.9% (68 cases) compared to 2010 when 525 cases were notified.

Of the notifications in 2011, 291 were respiratory cases, fewer than the 326 in 2010, and 166 were non-respiratory compared to 199 in 2010.

The decrease in notifications is also mirrored by Enhanced Surveillance of Mycobacterial Infections (ESMI). The ESMI scheme provisionally reported 453 cases in 2011, compared to 503 in 2010 which is the first decrease in numbers reported to ESMI since 2005.
