If you are diagnosed with chlamydia, gonorrhea, HIV, hepatitis, chancroid, or syphilis, your doctor is supposed to tell the local health department—which will then inform the CDC.

Diseases reportable to the CDC include:

• Anthrax.
• Arboviral diseases (diseases caused by viruses spread by mosquitoes, sandflies, ticks, etc.) such as West Nile virus, eastern and western equine encephalitis.
• Babesiosis.
• Botulism.
• Brucellosis.
• Campylobacteriosis.
• Chancroid.
• Chickenpox.

Nationally Notifiable Diseases

• Cholera.
• Cryptosporidiosis.
• Cyclosporiasis.
• Giardiasis.
• Hepatitis A.
• Legionellosis.
• Malaria*
• Salmonellosis.

‘Notifiable’ diseases are animal diseases that you’re legally obliged to report to the Animal and Plant Health Agency ( APHA ), even if you only suspect that an animal may be affected. …

Registered medical practitioners ( RMPs ) have a statutory duty to notify the ‘proper officer’ at their local council or local health protection team ( HPT ) of suspected cases of certain infectious diseases. Complete a notification form immediately on diagnosis of a suspected notifiable disease.

Parvovirus B19 is not a notifiable disease and testing practice is likely to vary around the country: with the exception of women presenting with a rash illness in pregnancy, there is no recommendation for routine testing for parvovirus B19.

This disease is notifiable in Scotland. Cases of food poisoning and infectious bloody diarrhoea are notifiable in the rest of the UK. See also the separate articles on Gastroenteritis in Children and Gastroenteritis in Adults and Older Children. Escherichia coli O157 is an uncommon cause of infectious gastroenteritis.

In severe infection, piperacillin and tazobactam, imipenem and cilastatin, or meropenem may be used. Combination therapy with antibiotics that cover E coli plus an antianaerobe can also be used (eg, levofloxacin plus clindamycin or metronidazole).
