Are of American Indian or Alaska Native heritage. Swine flu is an infection caused by a virus. There is no need for a repeat test. During low influenza activity (eg, summer months in the United States), a diagnosis of influenza should be considered for ill international travelers or their ill contacts [8588] because influenza viruses circulate year-round among persons living in the tropics and during winter periods in temperate climates of the Southern Hemisphere [89, 90]. Given the possibility of clinical deterioration following an initial clinical response if antivirals are stopped prior to a substantial antiviral effect, continuing antiviral treatment may be beneficial beyond 5 days, but the appropriate treatment duration has not been defined. Two studies conducted during 20082009 when H275Y H1N1 virus variants (oseltamivir resistant, but amantadine and zanamivir susceptible) circulated in the community suggested that treatment with zanamivir or a related drug, laninamivir, had superior clinical outcomes compared to oseltamivir [347, 348]. Consultation should be sought with an expert on management of patients with antiviral-resistant influenza virus infection. Combination antiviral therapy with 2 or more active agents with different mechanisms of action is an investigational approach that may reduce the development of additional de novo resistance in immunocompromised patients and other patients at higher risk for the emergence of resistant viruses during or after therapy [354, 355]. At the beginning of each meeting, whether face-to- face or by teleconference, panelists were required to disclose any new potential COI or prior relevant COI to the subject matter to be discussed. IX. A prospective study of >500 influenza patients in North Carolina reported that emergency department patients commonly reported cough, nasal congestion, fever, fatigue/malaise, headache, poor appetite, sore throat, and myalgias/muscle aches, whereas hospitalized patients reported shortness of breath and wheezing [33]. Have a body mass index above 40, which is defined as morbid obesity. Are in a hospital, nursing home or other long-term care facility. Zanamivir is administered as an orally inhaled powder, concentrated in the respiratory tract with limited systemic absorption that is excreted unchanged by the kidneys. Following global consultations with multiple stakeholders, the WHO posted a comprehensive influenza research agenda in 2009 that addressed research gaps including surveillance, the animalhuman interface, novel influenza A virus infections, transmission, vaccines and other prevention strategies, diagnostics, disease pathogenesis, antivirals, and clinical management. Use an over-the-counter pain reliever, such as acetaminophen (Tylenol, others) or ibuprofen (Advil, Motrin IB, others). There are limited data to inform when clinical response to antiviral treatment can be expected in patients with influenza. There is no validated immunoglobulin M assay or other available serologic assay to diagnose seasonal influenza virus infection in a single serum specimen. There are also very limited data on the safety or effectiveness of the investigational drug IV zanamivir in pregnancy [285, 286]. Cleveland Clinic is a non-profit academic medical center. Antiviral chemoprophylaxis is not a substitute for influenza vaccination. Testing of lower respiratory tract specimens by RT-PCR in critically ill patients with respiratory failure can yield higher detection of influenza viruses compared with upper respiratory tract specimens [121, 122]. Lower respiratory tract bacterial coinfection with influenza carries significant morbidity [122, 305, 306]. Pregnant women: Metabolism of oseltamivir is increased in pregnancy, reducing exposure to oseltamivir carboxylate by 30% compared to nonpregnant women [269, 270]. The farmhouse contains a screw-type agitating composting treatment facility with capacity of 330 m 2. While current evidence is limited, corticosteroid treatment of influenza patients should be avoided unless clinically indicated for other reasons (eg, exacerbation of asthma, COPD, low-dose hydrocortisone for adrenal insufficiency or refractory septic shock), as the risks of corticosteroid treatment are not balanced by a documented clinical benefit in the treatment of influenza [361]. One observational study reported that early corticosteroid treatment (within 72 hours of illness onset) of patients with influenza A(H1N1)pdm09 virus infection was associated with increased mortality [369]. Documented increased morbidity and mortality of influenza in newborn and very young infants should be balanced by the anticipated benefits of therapy given the available limited pharmacokinetics and safety data in this very young population [6]. Real-time surveillance by the Integrated Disease Surveillance Programme (IDSP) shows that 955 cases of H1N1, also referred to as swine flu, have been reported by states till February 28. People do not normally get swine flu, but human infections can and do happen. During 20102018, seasonal influenza epidemics were associated with an estimated 4.323 million medical visits, 140 000960 000 hospitalizations, and 1200079 000 respiratory and circulatory deaths each year in the United States [9]. Routine investigations should be performed for the patient who presents with these symptoms. All showed statistically significant protection; the pooled estimate of efficacy against laboratory-confirmed symptomatic influenza for the 3 trials was 79% (95% CI, 67%87%) [398]. Data are limited to inform recommendations regarding when an influenza outbreak should be declared in a long-term care facility or hospital, and on the effectiveness of interventions to prevent or control institutional influenza outbreaks. Studies of other drugs with immune-modulating activity, such as the hydroxy-methylglutaryl-coenzyme A reductase inhibitors (statins), have been proposed as adjunctive therapy for influenza, but no prospective data are available on which to make recommendations [381]. Meta-analyses of RCTs among outpatients with laboratory-confirmed influenza reported that oseltamivir treatment vs placebo was significantly associated with vomiting (relative risk [RR], 1.63) in children [200] and nausea (RR, 1.6; risk difference, 3.7%) and vomiting (RR, 2.43; risk difference, 4.7%) in adults [194]. There are very limited data to inform the use of antiviral chemoprophylaxis beyond affected units during influenza outbreaks in long-term care facilities. Rapid antigen These guidelines provide advice to clinicians on the use of tests will be less useful once the pandemic is established. Immunofluorescence assays require laboratory expertise and a fluorescent microscope, and take longer to produce results than RIDTs, rapid molecular assays, and some RT-PCR assays, but have generally better sensitivity and specificity than RIDTs [185, 186]. In one study, oral oseltamivir was 74% effective (95% CI, 53%88%; attack rate, 4.8% vs 1.3%) in preventing symptomatic laboratory-confirmed influenza when given to predominantly healthy unvaccinated adults for 42 days [384]. The risk of wider influenza virus transmission likely increases as the number of influenza cases increases and as the time extends between onset of the first cases, recognition of the outbreak, and implementation of interventions. Any revision to the guideline will be submitted for review and approval to the IDSA SPGC and Board of Directors. CDC continues to recommend influenza vaccination and prompt antiviral treatment of high-risk outpatients and hospitalized patients with suspected influenza. These clinical practice guidelines are an update to the guidelines published by the IDSA in 2009, prior to the 2009 H1N1 influenza pandemic. Centers for Disease Control and Prevention. If you have a chronic respiratory disease, your doctor may prescribe additional medications to help relieve your symptoms. These include: Respiratory droplets and aerosols. Accessed Oct. 13, 2020. We examine evidence for benefits of antiviral usage for influenza treatment, including its relation to severe outcomes for the current pandemic H1N1 strain. Interim Guidance for Correctional and Detention Facilities on Novel Influenza A (H1N1) Virus May 24 Interim Biosafety Guidance for All Individuals handling Clinical Specimens or Isolates containing 2009-H1N1 Influenza A Virus (Novel H1N1), including Vaccine Strains Aug 15 Infection Control in Outpatient Hemodialysis Centers May 8 Laboratory Testing Swine Flu (H1N1) DOs and DON'Ts Ayurveda Interventions for Prevention and Management of Common Flu like conditions Unani Perspective regarding Swine Flu (Nazla Wabai) List of Hospitals for Management of Seasonal Influenza A (Flu) Swine Flu (H1N1) Helpline Number: 011-23921401 Information on Swine Flu-H1N1 (Seasonal Influenza) from MoHFW Similar findings were reported in a systematic review of oseltamivir RCTs in children and adults [254]. How long should antiviral chemoprophylaxis be given to residents during an influenza outbreak in a long-term care facility? Therefore, antiviral treatment should be initiated as soon as possible in hospitalized patients, high-risk persons, and those with severe or progressive disease if influenza is suspected, irrespective of receipt of influenza vaccine. Are pregnant or within two weeks of delivery, including women who have had pregnancy loss. One study that utilized a pharmacokinetic model based upon data from samples collected from neonates treated with oseltamivir suggested use of lower oseltamivir doses in premature (1 mg/kg) and term infants (2 mg/kg) [263]. Novel H1N1 Influenza Practice Assessment School Nurses: On the Frontline in the Battle Against Influenza Ethical Dilemmas for Healthcare Professionals: Can We Avoid Influenza? There are no data to support the use of higher doses of oseltamivir in this population. Immunotherapy with plasma, immune serum globulin, or IVIg can result in immune-modulating as well as virus neutralizing activity. In a study of adult transplant patients, the CDC criteria of ILI, defined as fever and either cough or sore throat, were poorly predictive of RT-PCRpositive cases [78]. The decision to test is related to the level of suspicion for influenza, local influenza activity, and the sensitivity and specificity of available influenza tests. One study estimated that during 20102016, the seasonal incidence of symptomatic influenza among all ages in the United States was approximately 8% and varied from 3% to 11% [1]. 2020; doi:10.15585/mmwr.rr6908a1. During influenza activity (defined as the circulation of seasonal influenza A and B viruses among persons in the local community) (see Figure 1): Clinicians should test for influenza in high-risk patients, including immunocompromised persons who present with influenza-like illness, pneumonia, or nonspecific respiratory illness (eg, cough without fever) if the testing result will influence clinical management, Clinicians should test for influenza in patients who present with acute onset of respiratory symptoms with or without fever, and either exacerbation of chronic medical conditions (eg, asthma, chronic obstructive pulmonary disease [COPD], heart failure) or known complications of influenza (eg, pneumonia) if the testing result will influence clinical management, Clinicians can consider influenza testing for patients not at high risk for influenza complications who present with influenza-like illness, pneumonia, or nonspecific respiratory illness (eg, cough without fever) and who are likely to be discharged home if the results might influence antiviral treatment decisions or reduce use of unnecessary antibiotics, further diagnostic testing, and time in the emergency department, or if the results might influence antiviral treatment or chemoprophylaxis decisions for high-risk household contacts (see recommendations 4042). Higher sensitivity to detect influenza viruses in respiratory specimens has been reported for one rapid molecular assay (isothermal nucleic acid amplification) than for rapid antigen detection tests [117119], and a meta-analysis of rapid molecular assays reported pooled sensitivities of 92% and 95% for detection of influenza A and B viruses, respectively, and pooled specificities of 99% [111]. Also, a surface test method, which involved drying an amount of virus on a surface and then applying the inactivation methods for 1 minute of contact time, was used to determine the virucidal activity. All healthcare personnel should receive annual influenza vaccination [453]. Currently there are no guidelines for home isolation or area wide testing for H3N2, he added. Hospitalized children and adults with chronic illness who develop nosocomial influenza may not initially manifest typical influenza signs and symptoms [434, 435]. You're at high risk of complications from the flu, You live with someone who is at greater risk of flu complications, Heart problems, such as heart failure or an infection of the heart muscle, Lung and breathing problems, such as asthma or pneumonia, Brain and nervous system problems, such as encephalopathy or encephalitis. There are no data available that provide an estimate of how often a single identified laboratory-confirmed influenza case represents the start of an influenza outbreak. There is no need to discontinue breastfeeding due to the use of oral oseltamivir. Therefore, higher dosing of oseltamivir can be considered, especially for pregnant women who are hospitalized with influenza complications, although there are no safety data supporting higher doses in pregnancy. Although oseltamivir carboxylate is detectable at low concentrations in the breastmilk of lactating women who received oseltamivir [276], the benefits of oseltamivir treatment of influenza in the mother outweigh any potential risk of exposure in the infant. Cough and fever provide the most predictive signs and symptoms when influenza viruses are circulating in the community [126]. As the field of approved influenza diagnostics is dynamic, clinicians should consult the CDC website for information on FDA-cleared tests (https://www.cdc.gov/flu/professionals/diagnosis/index.htm). As such, considerable uncertainty remains about how, when, and for whom antiviral chemoprophylaxis should be used for these other institutional settings. Serologic testing results from a single serum specimen cannot be reliably interpreted, and collection of paired (acute/convalescent) sera 23 weeks apart are needed for serological testing. . Although postmarketing reports of severe abnormal behavior in adolescents with influenza after starting oseltamivir treatment have been reported primarily in Japan, no differences in the estimated incidence of life-threatening abnormal behavior were identified among patients treated with 4 different NAIs, including oseltamivir, in Japan [255]. A patient may be infected with NAI-resistant influenza virus circulating in the community, or resistance may develop during therapy. However, a small number of observational studies and one meta-analysis of observational studies of hospitalized influenza patients reported that NAI treatment did not have survival benefit [203, 211, 212]. https://www.wolterskluwercdi.com/facts-comparisons-online/. Clinicians should start antiviral treatment as soon as possible for adults and children with documented or suspected influenza, irrespective of influenza vaccination history, who meet the following criteria: Persons of any age who are hospitalized with influenza, regardless of illness duration prior to hospitalization, Outpatients of any age with severe or progressive illness, regardless of illness duration, Outpatients who are at high risk of complications from influenza, including those with chronic medical conditions and immunocompromised patients, Children younger than 2 years and adults 65 years, Pregnant women and those within 2 weeks postpartum. Based on seasonal influenza virus susceptibility patterns observed through virologic surveillance from 2009 through 2017, the use of an NAI is recommendedeither oral oseltamivir, inhaled zanamivir, or intravenous (IV) peramivir for early treatment of uncomplicated influenza in pediatric and adult patients. Annual influenza vaccination can prevent influenza, but influenza vaccine effectiveness has ranged from low to moderate in preventing medically attended outpatient visits and hospitalizations, and may have lower effectiveness in immunocompromised patients, who may also experience prolonged influenza viral replication [134]. Mayo Clinic. In this situation, antiviral treatment dosing should be continued for a full treatment course (twice daily) for 5 days before reducing to the recommended chemoprophylaxis dosing (once daily) until the outbreak is declared over. Use of a flocked nasal swab (with fibers projecting outward) may increase the detection of influenza viruses over a nonflocked swab and have a similar yield as NP aspirate [156]. III. In a patient with suspected or confirmed influenza, when should bacterial coinfectoin of the upper or lower respiratory tract be considered, investigated, and treated? Each test has strengths and weaknesses and a thoughtful diagnostic approach is important (see information on influenza testing and clinical algorithms available on the CDC website: https://www.cdc.gov/flu/professionals/diagnosis/index.htm). AA. However, other studies of infants born to women who had laboratory-confirmed influenza during pregnancy have not shown higher rates of prematurity, preterm labor, low birth weight, or lower Apgar scores compared with infants born to uninfected women [230, 241, 242]. antiviral agents for H1N1 influenza 09, drawing on studies of seasonal and H5N1 (avian) influenza, emerging data on H1N1 Recommendations for use of antiviral treatment for influenza: Neuraminidase inhibitors 'In India, viral illnesses caused by H3N2, COVID-19, and swine flu are on the rise. Guide for considering influenza testing when influenza viruses are circulating in the community. AAP Committee on Infectious Diseases. Multiple studies have reported that rapid influenza diagnostic tests (antigen detection) have low to moderate sensitivity. There was no significant difference in the primary endpoint, laboratory-confirmed clinical influenza, in the intent-to-treat population (2.9% vs 2.1%; 95% CI, 2.3 to 4.1; efficacy, 28%); a borderline significant benefit was detected in a secondary analysis using RT-PCR and excluding patients who were RT-PCR positive at study entry (3.0% vs 0.04%; 95% CI, .15.7; efficacy, 86%) [394]. For this update, the IDSA chose 2 co-chairs to lead the process and convened a multidisciplinary panel of 16 experts in infectious diseases and the management of patients with influenza. Once the analyses were completed, recommendations were reviewed and revised as appropriate by the panel. Specific guidance on evaluation and management of specific problems is beyond the scope of these guidelines.
