Epidemiological Bulletin: Flood Response in Pakistan
The objective of this weekly epidemiological bulletin is to provide a snap shot on selected health events reported from the communities affected by the current flood in Pakistan. While every attempt is made to present the weekly trend of the epidemic prone diseases, the information presented in the bulletin needs to be interpreted in the context that precise information on the reference populations is not always available, The bulletin also includes information collected by DEWS teams established during earlier emergencies, including 2005 earthquake, 2007 floods and 2008 ID crises. The primary focus of DEWS is the early detection of epidemic prone diseases, to facilitate a rapid public health response. We would like to thank all the numerous national and international partners who have contributed to the Disease Early Warning System.
Appearing in April 2009, the novel strain of Influenza A H1N1(2009) virus caused serious disease in younger age groups, but overall the disease caused by this pandemic strain last year was milder than expected with low mortality rate globally (0.45%), comparable to seasonal influenza. In Pakistan, 294 cases of Influenza A H1N1(2009) were lab-confirmed at NIH including 29 deaths. In August 2010, WHO announced the end of the pandemic period, but recommended clinicians to remain vigilant and treat all suspected cases of H1N1 appropriately. The virus causes acute respiratory illness with high-grade fever, dry cough, headache, muscle and joint pains, sore throat, runny nose and sometimes vomiting and diarrhoea. The disease is spread through contact with droplets generated by coughing or sneezing of infected person in air or on contaminated surfaces. It is contagious from one day prior to the appearance of symp-toms and has an incubation period of 1-7 days. Management:
• The goal of treatment is to alleviate the symptoms. Warm fluids and bed rest are advisable until the fever has subsided. • A mild analgesic such as paracetamol 0.5 - 1g every 4-6 hours usually relieves the headache and generalized pains and meds such as pholcodine 5 -10mg 3-4 times daily may be used to suppress unproductive cough. • While antibiotics are not effective against viruses, specific treatment of complications such as bronchitis and pneumo nia may be necessary. • High risk patients, including pregnant women and children under age 5 years, should be treated with anti-virals osel tamivir or zanamivir as early as possible, preferably not later than 48 hours after onset of the symptoms to assure a posi tive clinical outcome.
Prevention & Control Measures:
• Annual winter immunization with seasonal anti-influenza vaccine containing H1N1(2009) antigen is recommended for health workers, pregnant women, young children, and patients suffering from pulmonary, cardiac or renal disease. • Improve ventilation in living places; avoid close contact with ill people and crowded settings. • Wash your hands thoroughly with soap and water. • Avoid touching mouth and nose. • Encourage sufferer to cover their faces with a mask or handkerchief when coughing and sneezing.
IHR: Under the International Health Regulations, WHO should be immediately notified if any of the following changes are de-tected:
• sustained transmission of antiviral-resistant H1N1 2009 influenza • human cases of infection with any influenza virus not currently circulating in human populations • any notable changes in the severity or other epidemiological or clinical characteristics of the H1N1 2009 virus, inclu- ding changes in the age distribution, the clinical appearance, proportion of cases requiring intensive management, or unexpected increases in numbers of cases.
Phase 2 Mass immunization campaign is planned in some districts of Sindh and Balochistan from 5th to 16th January and in Punjab and Khyber Pakhtunkhwa from 10th to 22nd January.
Planned districts are as follows:
8 Districts of Sindh: Dadu, MirpurKhas, Jacobabad, Sanghar, Tando M. Khan, Tando Allah Yar, Tharparkar, Umer Kot; 4 Districts of Balochistan: Barkhan, Kohlu, Jhal Magsi, Bolan 11 Districts of Punjab: Attock, Chakwal, Gujrat, Hafizabad, Jhang, Lahore, Multan, Nankanasahib, Rawalpindi, Sargodha, Sialkot; and 7 Districts of Khyber Pakhtunkhwa: Bannu, Battagram, Karak, Lakki Marwat, Haripur, Abbotabad, Mansehra.
Focus on: Influenza A H1N1(2009)
