Disease Early Warning System

Disease Early Warning System

World Health Organization
Disease Surveillance World Health Organization 27 April 2017 Surveillance is the ongoing systematic collection, collation, analysis and interpretation of data; And, dissemination of information to those, who need to know, in order that action may be taken. Future planning can also be made on the basis of surveillance and on the incidence and prevalence of diseases according to area. Preparedness plans can also be made on the basis of previous data for endemic diseases that are seasonal, like cholera or respiratory infections.

Objective World Health Organization 27 April 2017 To ensure timely detection, response and control of outbreaks by early detection at local level by time and place clustering of cases among IDPs and resident population To monitor trends of communicable diseases in order to take appropriate public health actions To estimate workload of different health units involved in the system to rationalize resource allocation Active surveillance means to verify and investigate and validate the diseases in the community and to detect more cases in the community. Passive means we don't verify and investigate and send the data without verification. Both types of surveillance have uses – passive surveillance may give you the information you need for future planning, for example, but active surveillance is what the DEWS is most used for – detecting cases of diseases we are concerned about and dealing with them before they get worse.

Types of Surveillance 27 April, 2017 Active: Active surveillance means to verify and investigate and validate the diseases in the community and to detect more cases in the community (more accurate, timely, short periods, more resource intensive) Passive: Passive means we don't verify and investigate and send the data without verification. – passive surveillance may give you the information you need for future planning In many countries, health workers are required to report on the number of individuals that come to their facility and are diagnosed with reportable diseases. These reportable diseases are usually diseases that have outbreak potential, such as cholera, polio, and measles, or diseases that are targets of national control programs, such as malaria and tetanus. Data on individual patients, which are recorded in patient registers, are used to calculate the number of cases of reportable diseases diagnosed by health facility staff over a certain period of time. These data are periodically reported to district authorities who compile and send them to higher administrative levels. This process of detecting and reporting information on diseases that bring patients to the health facility is known as passive surveillance. Passive surveillance yields only limited data because many sick people do not visit a health facility and because those cases that do show up may not be correctly classified, recorded, or reported. If managers fail to fully understand and account for these limitations, they may incorrectly interpret trends and patterns of infectious diseases. One way to overcome the limitations of passive surveillance and get a better picture of disease burden in the community is for health workers to visit health facilities and communities to seek out cases. This is known as active surveillance. Since passive surveillance has limitations due to its lack of access to some groups within the population, active surveillance is often used to enhance the completeness of a passive surveillance system. Active surveillance is also more expensive than a passive system and requires considerable additional effort to organize. This means that active surveillance is usually conducted on a limited segment of the population and for only a brief period. Active surveillance is, therefore, used to gain targeted insight into a situation and not collect routine data over a long period of time. Routine surveillance by health facilities, whether passive or active, is often hampered by the difficulty of making accurate diagnoses. health workers may lack the proper equipment or training for diagnosis in the health facility, and laboratory services are often not available to confirm clinical diagnoses. In certain instances, health workers conduct case-based investigations to learn more about a specific illness pattern, for example, when there is a suspected case of a disease targeted for eradication, such as polio, or during suspected outbreaks of epidemic- prone diseases such as yellow fever. In case-based investigations, health workers record information such as the patient’s name, age, vaccination status, location, date of disease onset, suspected diagnosis, and laboratory results (when available).

27 April 2017 Prevention and Management of Diarrhea (Acute, Bloody, and Suspected Cholera)

Case Definitions World Health Organization 27 April 2017 Cholera Suspected case: In an area where the disease is not known to be present: severe dehydration or death from acute watery diarrhoea in a patient aged 5 years or more. For management of cases of acute watery diarrhoea in an area where there is a cholera epidemic, cholera should be suspected in all patients with acute watery diarrhoea. Acute Diarrhea Three or more abnormally loose or fluid stools in past 24 hours with or without dehydration. Bloody Diarrhea Acute diarrhea with visible blood in stools This is a reminder of the case definitions, which you have seen before Any of these are prone to epidemics, particularly among displaced persons or after disasters, when clean water is not available and hygiene standards are difficult to maintain Much of the prevention and management for these three different diseases is the same, though there are some differences. You should not wait for confirmation before starting to treat cases, particularly in suspected cholera.

When to Worry World Health Organization 27 April 2017 For Cholera: 1 case For Acute Diarrhea and Bloody Diarrhea: A sudden increase and clustering of cases If you see a single case of cholera, there are probably more, so you should investigate if possible and check all the people who have been in contact with the case. Diarrhea is more common, and therefore a few cases is not necessarily something to worry about. However, if the number of cases suddenly rises, you may have a problem and should take steps to find the cause and stop it – you may not be able to stop it yourself, and may need to ask for help from the department of health, who can make an investigation.

Modes of Transmission World Health Organization 27 April 2017 Oral/fecal transmission unclean water contaminated food poor hygiene practices lack of latrines In a situation such as flooding, it can be expected that water will become contaminated both at the source and in the home, if the home itself is flooded, making diarrhea or cholera more likely. Damage to infrastructure may make good hygiene practices more difficult.

Prevention – for Patients
World Health Organization 27 April 2017 Water must be decontaminated – boiling or chlorinating Water should be boiled for a minimum of 15 minutes after reaching boiling point Chlorine tablets can also be used to purify water and should be given to families of the patients The key for stopping outbreaks of diarrhea is usually making sure that everyone has safe drinking water. By giving patients directions on how to make water safe, you may prevent further cases Boiling is the preferred method – chlorine makes the water taste unpleasant, and can be unacceptable for some people, making them less likely to use the safe drinking water.

Food and Hygiene World Health Organization 27 April 2017 Wash hands with soap after toilet use, or after contact with fecal matter Wash hands before preparing or eating food, or before feeding children. Cooked food and eating utensils should be kept separate from uncooked foods and potentially contaminated utensils. Cook food until it is hot throughout and eat while still hot or reheat thoroughly before eating. Avoid raw food except fruits and vegetables that can be peeled in hygienic manner. Wash cooking and serving utensils with soap thoroughly after use. Since we know that transmission is through fecal/oral route, all control should be of these two elements. Hand washing is key, as is making sure that food is not contaminated. Giving this advice to patients will help stop outbreaks and does not cost anything Street food in particular can be very dangerous, and the advice to eat only hot cooked foods applies to this too. Avoid street drinks unless they are bottled or canned. Avoid ice.

Sanitation World Health Organization 27 April 2017 Good sanitation is necessary to avoid contamination of clean water sources. Human waste disposal at appropriate distance from water source and supply – minimum 10 metres Faecal material and vomit must be properly disinfected and disposed of. Health education programmes should be conducted on hygiene and disinfection measures with simple messages on safe water, safe food and hand-washing. Funerals should be held quickly and near the place of death. Those who prepare the body for burial must be meticulous about washing their hands with soap and clean water IDP camps should have sufficient latrines. However, for people who are not in camps, but with damaged homes, advice on proper hygiene practices may be useful. They can be advised to dig a latrine if their home is destroyed, but it should be a minimum of 10 metres away from any water source. Health education messages can be given by health care providers, but also by mosques, the media, or others. Those preparing bodies for burial must be very careful and wash thoroughly. If possible, provide an appropriate disinfection solution. Burials should be as soon as possible after death.

Management of cholera or acute diarrhea in the camp or facility
World Health Organization 27 April 2017 First line treatment: The key to therapy is the provision of adequate rehydration Patients should be assessed for the degree of dehydration This table shows how to assess for level of dehydration simply by looking at the patient and doing a skin pinch. In some infants and children the eyes normally appear somewhat sunken. It is helpful to ask the mother whether the child’s eyes are normal or more sunken than usual. Dryness of the mouth and tongue can also be palpated with a clean finger. The mouth may always be dry in a child who habitually breathes through the mouth. The mouth may be wet in a dehydrated patient owing to recent vomiting or drinking. The skin pinch is less useful in infants or children with marasmus (wasting) or kwashiorkor (severe malnutrition with edema) or in obese children. Treatment will differ by degree of dehydration

Treatment by Dehydration Level
World Health Organization 27 April 2017 Plan A Dehydration is mild and can be treated at home Give the patient plenty of food to prevent malnutrition Continue to breastfeed babies frequently If the child is not breastfed, give the usual milk If the child is 6 months or older, or already taking solid food: Also give cereal or other starchy food mixed, if possible, with pulses, vegetables, and meat or fish; add one or two teaspoonsful of vegetable oil to each serving Give fresh fruit juice or mashed banana to provide potassium Give freshly prepared foods; cook and mash or grind food well Encourage the patient to eat: offer food at least six times per day Give the same food after diarrhea stops and give an extra meal each day for 2 weeks. Take the patient to the health worker if he/she does not get better in 3 days or develops any of the following: Many watery stools Repeated vomiting Marked thirst Eating or drinking poorly Fever Blood in the stool

Plan B World Health Organization 27 April 2017 If a patient fits into Plan B, they have moderate dehydration and need immediate care to prevent it from becoming more severe. Actions to take in the first four hours: If the child wants more ORS than shown in the chart, give more Encourage mothers to continue breastfeeding For infants less than 6 months who are not breastfed, also give ml of clean water during the first four hours Observe the child carefully and help the mother give ORS, showing her how much and frequency Check from time to time to see if there are problems If the child vomits, wait 10 minutes and continue giving, but more slowly If the child’s eyelids become puffy, stop the ORS and give plan water or breastmilk. Give ORS according to Plan A when the puffiness is gone After 4 hours, reassess the child using the assessment chart, then select Plan A, B, or C to continue If there are no signs of dehydration, shift to Plan A. When dehydration has been corrected the child usually passes urine and may also be tired and fall asleep If signs indicating some dehydration are still present, repeat Plan B, but start to offer food, milk, and juice as described in Plan A If signs indicating severe dehydration have appeared, shift to Plan C If the mother must leave before completing treatment Plan B: Show her how much ORS to give to finish the 4 hour treatment at home Give her enough ORS packets to complete rehydration, and for 2 more days as shown in Plan A, and show her how to prepare ORS solution Explain to her the three rules in Plan A for treating children at home: Give ORS or other fluids until diarrhea stops Feed the child Bring the child back to the health worker, if necessary

Plan C World Health Organization 27 April 2017 Start IV fluids immediately. If the patient can drink, give ORS by mouth while the drip is set up Give 100 ml Ringer’s lactate solution per kg of body weight (or if not available, give normal saline), divided as follows: Age First give 30ml/kg in: Then give 70ml/kg in: Infants (under 12months) 1 hour* 5 hours Older 30 minutes* ½ hours * Repeat once if radial pulse is still very weak or undetectable. Reassess the patient every 1-2 hours. If hydration is not improving, give the IV drip more rapidly. Also give ORS (about 5 ml/kg per hour) as soon as the patient can drink: usually after 2-4 hours (infants) or 1-2 hours (older patients). After 6 hours (infants) or 3 hours (older patients), evaluate the patient using the assessment chart. Then choose the appropriate Plan (A, B or C) to continue treatment. Do not use glucose, use Ringers lactate If condition is not improving after the first 6 hours in infants or 3 hours in adults, Start rehydration by tube with ORS solution: give 20ml/kg per hour for 6 hours (total of 120 ml/kg). Reassess the patient every 1-2 hours: - if there is repeated vomiting or increased abdominal distension, give the fluid more slowly; - if hydration is not improved after 3 hours, send the patient for IV therapy. After 6 hours, reassess the patient and choose the appropriate treatment plan.

Antibiotics for Cholera
World Health Organization Antibiotics for Cholera 27 April 2017 Antibiotic therapy is not essential to the management of Cholera. Effective rehydration therapy is life saving. Antibiotics should only be given in severe cases to reduce the duration of symptoms and reduce carriage of the pathogen Oral antimicrobials only must be given, and after the patient has been rehydrated (usually in 4–6 hours) and vomiting has stopped.

Remember 27 April 2017 No anti-diarrheal, anti-emetic, anti-spasmodic, or corticosteroid drugs should be used to treat Cholera. Blood Transfusion and plasma volume expanders are not recommended.

Establishment of Diarrhea Treatment Centre
World Health Organization 27 April 2017 If you have a large number of cases spread of the disease will be prevented by isolating patients and treating them in a treatment centre A diarrhea treatment centre consists of 4 sections: 1. Admission and observation 2. Neutral part – for staff. If the cholera centre is a tent facility being setup near an existing facility or hospital, this section can be omitted 3. Hospitalization unit - reserved for severe patients on IV 4.
