This interim steerage is for clinicians caring for sufferers with confirmed an infection with extreme acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus illness 2019 (COVID-19). CDC will replace this interim steerage as extra info turns into out there.
The incubation interval for COVID-19 is believed to increase to 14 days, with a median time of 4-5 days from publicity to signs onset.1-3 One examine reported that 97.5% of individuals with COVID-19 who develop signs will accomplish that inside 11.5 days of SARS-CoV-2 an infection.3
The indicators and signs of COVID-19 current at sickness onset differ, however over the course of the illness, most individuals with COVID-19 will expertise the next1,4-9:
- Fever or chills
- Shortness of breath or issue respiratory
- Muscle or physique aches
- New lack of style or odor
- Sore throat
- Congestion or runny nostril
- Nausea or vomiting
Signs differ with severity of illness. For instance, fever, cough, and shortness of breath are extra generally reported amongst people who find themselves hospitalized with COVID-19 than amongst these with milder illness (non-hospitalized sufferers). Atypical shows happen usually, and older adults and individuals with medical comorbidities might have delayed presentation of fever and respiratory signs.10,14 In a single examine of 1,099 hospitalized sufferers, fever was current in solely 44% at hospital admission however ultimately developed in 89% throughout hospitalization.1 Fatigue, headache, and muscle aches (myalgia) are among the many mostly reported signs in people who find themselves not hospitalized, and sore throat and nasal congestion or runny nostril (rhinorrhea) additionally could also be outstanding signs. Many individuals with COVID-19 expertise gastrointestinal signs akin to nausea, vomiting or diarrhea, generally previous to creating fever and decrease respiratory tract indicators and signs.9 Lack of odor (anosmia) or style (ageusia) previous the onset of respiratory signs has been generally reported in COVID-19 particularly amongst ladies and younger or middle-aged sufferers who don’t require hospitalization.11,12 Whereas most of the signs of COVID-19 are widespread to different respiratory or viral diseases, anosmia seems to be extra particular to COVID-19.12
A number of research have reported that the indicators Indicators and signs of COVID-19 in kids are much like adults differ by age of the kid, and are normally milder in comparison with adults.15-19 For extra info on the medical presentation and course amongst kids, see Data for Pediatric Healthcare Suppliers.
A number of research have documented SARS-CoV-2 an infection in sufferers who by no means develop signs (asymptomatic) and in sufferers not but symptomatic (pre-symptomatic).16,18,20-30 Since asymptomatic individuals aren’t routinely examined, the prevalence of asymptomatic an infection and detection of pre-symptomatic an infection is just not but effectively understood. One examine discovered that as many as 13% of reverse transcription-polymerase chain response (RT-PCR)-confirmed circumstances of SARS-CoV-2 an infection in kids had been asymptomatic.16 One other examine of expert nursing facility residents who had been contaminated with SARS-CoV-2 after contact with a healthcare employee with COVID-19 demonstrated that half of the residents had been asymptomatic or pre-symptomatic on the time of contact tracing, analysis, and testing.27 Sufferers might have abnormalities on chest imaging earlier than the onset of signs.21,22.
Growing numbers of epidemiologic research have documented SARS-CoV-2 transmission through the pre-symptomatic incubation interval,21,31-33. Virologic research utilizing RT-PCR detection have reported assessments with low cycle thresholds, indicating bigger portions of viral RNA and viable virus has been cultured from individuals with asymptomatic and pre-symptomatic SARS-CoV-2 an infection.25,27,30,34 The connection between SARS-CoV-2 viral RNA shedding and transmission danger is just not but clear. The proportion of SARS-CoV-2 transmission because of asymptomatic or pre-symptomatic an infection in comparison with symptomatic an infection is unclear.35
The most important cohort reported of >44,000 individuals with COVID-19 from China confirmed that sickness severity can vary from delicate to vital:36
- Delicate to reasonable (delicate signs as much as delicate pneumonia): 81%
- Extreme (dyspnea, hypoxia, or >50% lung involvement on imaging): 14%
- Essential (respiratory failure, shock, or multiorgan system dysfunction): 5%
On this examine, all deaths occurred amongst sufferers with vital sickness, and the general case fatality charge was 2.3%.36 The case fatality charge amongst sufferers with vital illness was 49%.36 Amongst kids in China, sickness severity was decrease with 94% having asymptomatic, delicate, or reasonable illness; 5% having extreme illness; and <1% having vital illness.16 Amongst U.S. COVID-19 circumstances with recognized disposition, the proportion of individuals who had been hospitalized was 19%.37 The proportion of individuals with COVID-19 admitted to the intensive care unit (ICU) was 6%.37
Amongst sufferers who developed extreme illness, the median time to dyspnea from the onset of sickness or signs ranged from 5 to eight days, the median time to acute respiratory misery syndrome (ARDS) from the onset of sickness or signs ranged from Eight to 12 days, and the median time to ICU admission from the onset of sickness or signs ranged from 10 to 12 days.5,6,10,11 Clinicians ought to pay attention to the potential for some sufferers to quickly deteriorate one week after sickness onset. Amongst all hospitalized sufferers, a variety of 26% to 32% of sufferers had been admitted to the ICU.6,8,11 Amongst all sufferers, a variety of three% to 17% developed ARDS in comparison with a variety of 20% to 42% for hospitalized sufferers and 67% to 85% for sufferers admitted to the ICU.1,4-6,8,11 Mortality amongst sufferers admitted to the ICU ranges from 39% to 72% relying on the examine and traits of affected person inhabitants.5,8,10,11 The median size of hospitalization amongst survivors was 10 to 13 days.1,6,8
Danger Components for Extreme Sickness
Age is a robust danger issue for extreme sickness, issues, and loss of life.1,6,8,14,36-40 Amongst >44,000 confirmed circumstances of COVID-19 in China, the case fatality charge was highest amongst older individuals: ≥80 years, 14.8%; 70–79 years, 8.0%; 60–69 years, 3.6%; 50–59 years, 1.3%; 40–49 years, 0.4%; <40 years, 0.2%.36,41 In early U.S. epidemiologic information, case fatality was highest in individuals aged ≥85 years (vary 10%–27%), adopted by these aged 65-84 years (3%–11%), aged 55-64 years (1%–3%), and aged <55 years (<1%).37
Sufferers in China with no reported underlying medical circumstances had an general case fatality of 0.9%. Case fatality was increased for sufferers with comorbidities: 10.5% for these with heart problems, 7.3% for these with diabetes, and roughly 6% for these with power respiratory illness, or most cancers.1,6,14,36,38,41,42 Prior stroke, diabetes, power lung illness, and power kidney illness have all been related to elevated sickness severity and hostile outcomes. Critical coronary heart circumstances, together with coronary heart failure, coronary artery illness, congenital coronary heart illness, cardiomyopathies, and pulmonary hypertension, might put folks at increased danger for extreme sickness from COVID-19. Individuals with hypertension could also be at an elevated danger for extreme sickness from COVID-19 and may proceed to take their drugs as prescribed. Presently, folks whose solely underlying medical situation is hypertension aren’t thought-about to be at increased danger for extreme sickness from COVID-19.43,44
Accounting for variations in age and prevalence of underlying situation, mortality related to COVID-19 reported in the USA has been much like stories from China.26,37,39
There are restricted information about reinfection with SARS-CoV-2 after restoration from COVID-19.84, 85 Whereas viral RNA shedding declines with decision of signs, it might proceed for days to weeks.34,38,45 Nevertheless, the detection of RNA throughout convalescence doesn’t essentially point out the presence of viable infectious virus. Medical an infection has been correlated with the detection of IgM and IgG antibodies.46-49 Nevertheless, definitive information are missing, and it stays unsure whether or not people with antibodies are protected in opposition to reinfection with SARS-CoV-2, and if that’s the case, what focus of antibodies is required to confer safety.
Prognosis of COVID-19 requires detection of SARS-CoV-2 RNA by reverse transcription polymerase chain response (RT-PCR). Detection of SARS-CoV-2 viral RNA is best in nasopharynx samples in comparison with throat samples.34,50 Decrease respiratory samples might have higher yield than higher respiratory samples.34,50 SARS-CoV-2 RNA has additionally been detected in stool and blood.15,45,47,51 Detection of SARS-CoV-2 RNA in blood could also be a marker of extreme sickness.52 Viral RNA shedding might persist over longer durations amongst older individuals and those that had extreme sickness requiring hospitalization (median vary of viral shedding amongst hospitalized sufferers 12–20 days).34,38,45,46,53
An infection with each SARS-CoV-2 and with different respiratory viruses has been reported, and detection of one other respiratory pathogen doesn’t rule out COVID-19.54

Lymphopenia is the commonest laboratory discovering in COVID-19, and is present in as many as 83% of hospitalized sufferers.1,5 Lymphopenia, neutrophilia, elevated serum alanine aminotransferase and aspartate aminotransferase ranges, elevated lactate dehydrogenase, excessive CRP, and excessive ferritin ranges could also be related to larger sickness severity.1,5,6,8,38,55 Elevated D-dimer and lymphopenia have been related to mortality.8,38 Procalcitonin is usually regular on admission, however might improve amongst these admitted to an ICU.4-6 Sufferers with vital sickness had excessive plasma ranges of inflammatory makers, suggesting potential immune dysregulation.5,56
Chest radiographs of sufferers with COVID-19 usually reveal bilateral air-space consolidation, although sufferers might have unremarkable chest radiographs early within the illness.1,5,57 Chest CT photos from sufferers with COVID-19 usually reveal bilateral, peripheral floor glass opacities.4,8,36,58-67 As a result of this chest CT imaging sample is non-specific and overlaps with different infections, the diagnostic worth of chest CT imaging for COVID-19 could also be low and dependent upon radiographic interpretation.59,68 One examine discovered that 56% of sufferers who offered inside two days of prognosis had a traditional CT.60 Conversely, different research have recognized chest CT abnormalities in sufferers previous to the detection of SARS-CoV-2 RNA.58,69 Given the variability in chest imaging findings, chest radiograph or CT alone is just not really useful for the prognosis of COVID-19. The American School of Radiology additionally doesn’t advocate CT for screening, or as a first-line check for prognosis of COVID-19. (See American School of Radiology Suggestionsexterior icon).
The Nationwide Institutes of Well being revealed tips on prophylaxis use, testing, and administration of sufferers with COVID-19. For extra info, please go to Nationwide Institutes of Well being: Coronavirus Illness 2019 (COVID-19) Therapy Tipsexterior icon. The suggestions had been primarily based on scientific proof and skilled opinion and shall be up to date as extra information change into out there.
Delicate to Reasonable Illness
Sufferers with a light medical presentation (absence of viral pneumonia and hypoxia) might not initially require hospitalization, and lots of sufferers will be capable to handle their sickness at house. The choice to observe a affected person within the inpatient or outpatient setting needs to be made on a case-by-case foundation. This determination will rely on the medical presentation, requirement for supportive care, potential danger components for extreme illness, and the flexibility of the affected person to self-isolate at house. Sufferers with danger components for extreme sickness (see Individuals Who Are at Greater Danger for Extreme Sickness) needs to be monitored intently given the attainable danger of development to extreme sickness, particularly within the second week after symptom onset.5,6,14,38
For info relating to an infection prevention and management suggestions, please see Interim An infection Prevention and Management Suggestions for Sufferers with Confirmed Coronavirus Illness 2019 (COVID-19) or Individuals Underneath Investigation for COVID-19 in Healthcare Settings.
Some sufferers with COVID-19 can have extreme illness requiring hospitalization for administration. Inpatient administration revolves across the supportive administration of the commonest issues of extreme COVID-19: pneumonia, hypoxemic respiratory failure/ARDS, sepsis and septic shock, cardiomyopathy and arrhythmia, acute kidney damage, and issues from extended hospitalization, together with secondary bacterial infections, thromboembolism, gastrointestinal bleeding, and significant sickness polyneuropathy/myopathy.1,4-6,14,36,38,70-73

Extra sources and steerage paperwork on the therapy and administration of COVID-19, together with inpatient administration of critically sick sufferers, are offered under.
Hypercoagulability and COVID-19
Some sufferers with COVID-19 might develop indicators of a hypercoagulable state and be at elevated danger for venous and arterial thrombosis of enormous and small vessels.74,75 Laboratory abnormalities generally noticed amongst hospitalized sufferers with COVID-19-associated coagulopathy embody:
- Delicate thrombocytopenia
- Elevated D-dimer ranges
- Elevated fibrin degradation merchandise
- Extended prothrombin time
Elevated D-dimer ranges have been strongly related to larger danger of loss of life.74,76-79
There are a number of stories of hospitalized sufferers with thrombotic issues, most ceaselessly deep venous thrombosis and pulmonary embolism.80-82 Different reported manifestations embody:
- Microvascular thrombosis of the toes
- Clotting of catheters
- Myocardial damage with ST-segment elevation
- Massive vessel strokes83-86
The pathogenesis for COVID-19-associated hypercoagulability stays unknown. Nevertheless, hypoxia and systemic irritation secondary to COVID-19 might result in excessive ranges of inflammatory cytokines and activation of the coagulation pathway.
There are restricted information out there to tell medical administration round prophylaxis or therapy of venous thromboembolism in COVID-19 sufferers.
A number of nationwide skilled associations present sources for up-to-date info regarding COVID-19-associated hypercoagulability, together with administration of anticoagulation. This can be a quickly evolving matter, with new info launched usually.

Sickness amongst pediatric sufferers with COVID-19 is usually milder than amongst adults. Most youngsters current with signs of higher respiratory an infection. Nevertheless, extreme outcomes have been reported in kids, together with deaths. Information recommend that infants (<12 months of age) could also be at increased danger for extreme sickness from COVID-19 in contrast with older kids.16 CDC and companions are additionally investigating stories of multisystem inflammatory syndrome in kids (MIS-C) related to COVID-19.
