Summary

COVID-19 virus possibly behaves like SARS; causes mild illness in 82%, severe illness in 15%, critical illness in 3% and death in 2% cases ( 15% of admitted serious cases, 71% with comorbidity); affects all ages but predominantly males (56%) with median age 59 years (2-74 years, less in children below 15); with mean incubation period 5.2 days (2-214 days); mean time to symptoms 5 days, mean time to pneumonia 9 days, mean time to death 14 days, 3-4 reproductive number R0 ( flu 1.2 and SARS 2); epidemic doubling time 7.5 days; has origin possibly from bats; spreads via large droplets and predominately from people having lower respiratory infections and hence standard droplet precautions are the answer for the public and close contacts and airborne precautions for healthcare workers dealing with the secretions.

Clinically all patients have fever, 75% have cough; 50% weakness; 50% breathlessness with low total white count and deranged liver enzymes. About 20% need ICU care and 15% of them are fatal.

Close Contacts are defined as healthcare-associated exposure, which includes providing direct care for COVID-19 patients, working with health care workers infected with COVID-19, visiting patients or staying in the same close environment of a COVID-19 patient OR working together in close proximity or sharing the same classroom environment with a with COVID-19 patient OR traveling together with COVID-19 patient OR Living in the same household as a COVID-19 patient OR the epidemiological link may have occurred within a 14-day period before or after the onset of illness in the case under consideration.

New updates

Namaste: Let’s not shake hands. Time for facts, not fear; for rationality, not rumors and for solidarity, not stigma. Help line India: +91-11-23978046, ncov2019@gmaildotcom, mohfw.gov.in/node/4904 Total number includes lab-confirmed plus CT-Ddagnosed cases. No reliable evidence to support the possibility of vertical transmission of COVID-19 infection from the mother to the baby. [Lancet Feb 20] There has been a sudden jump in deaths and new cases on 12th due to inclusion of CT-diagnosed cases. The National Health Commission of China, in its 14 Feb report deducted 108 previously reported deathsand 1,043 previously reported cases from the total in Hubei Province due to "repeated statistics." 218 (6%) cases have been confirmed on a ship quarantined in Japan (three Indians) Secondary Cases: Thailand, Taiwan, Germany, Vietnam, Japan, France, US, Korea. Five Deaths outside China: Philippines (Feb 2, 44-year-old Chinese man, primary, comorbid), Hong Kong (4th Feb 39 M, local, comorbid, primary), Japan (2 Feb, 18 F, Secondary), France (15 Feb, 80-yr, M, Chinese visitor), Taiwan. WHO warns epidemic could still ‘go in any direction’ and global experts say that the outbreak is just ‘beginning’ outside China. Coronavirus vaccine could be ready in 18 months (WHO). Human-to-human contact requires prolonged contact (possibly ten minutes or more) within three to six feet. 14th Feb: 1,716 medical workers have contracted the virus and six of them have died. Of those people, 1,502 were in Hubei Province, with 1,102 in Wuhan. National Health Commission, said the numbers of infected workers represented 3.8% of China’s overall confirmed infections as of Feb. 11. At least two workers who were sent to Wuhan at the end of January to help build one of the new hospitals to treat victims of coronavirus have been infected with it. The central banking authorities of China are disinfecting, stashing and even destroying cash in an attempt to stop the spread of the coronavirus. Fan Yifei, deputy governor of the People’s Bank of China, said that the cash collected by commercial banks must be disinfected before being released back to customers. Maharishi Valmiki Hospital in Delhi stops biometric attendance. China has more than 80 running or pending clinical trials on potential treatments for COVID-19. WHO demands to know more about sick doctors, insists group of 12 virus experts will reach Beijing over the weekend. Bangkok: A health worker has been found to have been infected by coronavirus, bringing the total number of infections in the country to 34 since January.

Public Health Emergency of International Concern - 30th January, 2020

Mandatory to report to WHO each human and animal case.

Prior 5 PHEICs:

26th April 2009 Swine flu: 10 August 2010, WHO announced that the H1N1 influenza virus has moved into the post-pandemic period. However, localized outbreaks of various magnitudes are likely to continue.

May 2014 Polio: resurgence of wild polio. October 2019, continuing cases of wild polio in Pakistan and Afghanistan, in addition to new vaccine-derived cases in Africa and Asia; the status was reviewed and it remains a PHEIC. It was extended on 11 December, 2019.

August 2014 Ebola: It was the first PHEIC in a resource-poor setting.

Feb 1 2016 Zika: link with microcephaly and Guillain–Barré syndrome. This was the first time a PHEIC was declared for a mosquito‐borne disease. This declaration was lifted on 18 November 2016.

2018–20 Kivu Ebola: A review of the PHEIC had been planned at the fifth meeting of the EC on 10 October 2019 and as of 18 October 2019, it continues to be a PHEIC.

Kerala: State public health emergency. Three primary cases in North, South and Central - Kasaragod district in north Kerala, Thrissur in central Kerala and Alappuzha in South Kerala. Four Karnataka districts bordering Kerala — Kodagu, Mangaluru, Chamarajanagar and Mysuru - have been put on high alert.

About the Virus

Single-strand, positive-sense RNA genome ranging from 26 to 32 kilobases in length, Beta corona virus from Corona family.

‘Corona’ means crown or the halo around the sun. Heart is considered crown and hence the arteries that supply oxygen to the heart are also called coronary arteries. Under an electron microscope, is the virus appears round with spikes poking out from its periphery.

Three deadly human respiratory coronaviruses: Severe acute respiratory syndrome coronavirus [SARS-CoV], Middle East respiratory syndrome coronavirus [MERS-CoV]) and COVID 19: The current virus is 75-80% identical to the SARS-CoV

Origin: Wuhan, China December 2019. 1st case informed to the world by Dr. Li Wenliang; died Feb 6.

The virus is likely to be killed by sunlight, temperature, and humidity. SARS stopped around May and June in 2003 probably due to more sunlight and more humidity. Alive on surface: possibly 3-12 hours.

Link to ACE: COVID-19 might be able to bind to the angiotensin-converting enzyme 2 receptor in humans.

Pathogenesis

High viral load: Detection of COVID-19 RNA in specimens from the upper respiratory tract with low Ct values on day 4 and day 7 of illness suggests high viral loads and potential for transmissibility. [NEJM]

COVID-19 uses the same cellular receptor as SARS-CoV (human angiotensin-converting enzyme 2 [hACE2]), so transmission is expected only after signs of lower respiratory tract disease develop.

SARS is high [unintelligible] kind of inducer. This means that when it infects the lower part of the lung, the body develops a very severe reaction against it and leads to lots of inflammation and scarring. In SARS, after the first 10 to 15 days, it wasn’t the virus killing the patients it was the body’s reaction. Is this virus in the MERS or SARS kind picture or is this the other type of virus which is a milder coronavirus like the NL63 or the 229? It may be the mild (unintelligible) kind of inducer. [Dr John Nicholls, University of Hong Kong]

COVID-19 seems to thrive better in primary human airway epithelial cells as compared to standard tissue-culture cells, unlike SARS-CoV or MERS-CoV. COVID-19 will likely behave more like SARS-CoV.

SARS-CoV and MERS-CoV affect the intrapulmonary epithelial cells more than cells of the upper airways. Transmission thus occurs primarily from patients with recognized illness and not from patients with mild, nonspecific signs. However, NEJM has reported a case of COVID-19 infection acquired outside of Asia wherein transmission occurred during the incubation period in the index patient, but the same has been challenged now.

This new virus attacks the lungs as well, and not just the throat. Patients so far have not presented with a sore throat, because COVID-19 attacks the intraepithelial cells of lung tissue.

Transmission

Zoonotic and linked to Huanan Seafood Wholesale Market as 55% with onset before January 1, 2020 originated there vs. only 8.6% of the subsequent cases. The Chinese government has banned wildlife trade until the epidemic passes.

This new coronavirus is closely related to bat coronaviruses. Bats are the primary reservoir. While SARS-CoV was transmitted to humans from exotic animals in wet markets, MERS-CoV transmitted from camels. The ancestral hosts were probably bats; however.

The virus has been traced to snakes in China. Snakes often hunt for bats. According to reports, snakes were sold in the local seafood market in Wuhan, thus raising the likelihood that COVID 19 might have moved from the host species, i.e., bats, to snakes and then to humans. It is still not understood as to how the virus could adapt to both the cold-blooded and warm-blooded hosts.

It cannot be transmitted by eating wild animals as it is a respiratory secretions disease.

It transmits predominantly via droplets, like common flu and not like airborne illnesses (TB, Measles, Chickenpox).

Kissing scenes have been banned in movies in China. In Kerala, air crew have been exempted from breath analyser tests and China has banned death ceremonies, people gathering together. NEJM reported a small cluster of five cases suggesting transmission from asymptomatic individuals during the incubation period; all patients in this cluster had mild illness. But the same has been challenged. Another case got infected while using gown, but eyes uncovered.

Serious illnesses in other countries are less as patients with breathlessness are unlikely to board and patients will mild illness or asymptomatic illness are less likely to transmit infections. NEJM reports of a taxi driver infected with SARS-CoV-2 in Thailand, potentially from Chinese tourists; the infection appears not to have spread to others.

Legal Implications India: Section 270 in the Indian Penal Code: 270. Malignant act likely to spread infection of disease danger­ous to life.—Whoever malignantly does any act which is, and which he knows or has reason to believe to be, likely to spread the infection of any disease dangerous to life, shall be punished with imprisonment of either description for a term which may extend to two years, or with fine, or with both.

Quarantine has Limitations

China has imposed quarantines across Hubei province, locking in about 56 million people, in an attempt to stop it from spreading. Millions of others cities far from the epicenter are also enduring travel restrictions.

Villages in Vietnam with 10,000 people close to the nations capital have also been placed under quarantine after six cases of the deadly coronavirus were identified there. The locking down of the commune of Son Loi, about 40 kilometres from Hanoi, is the first mass quarantine outside of China since the virus emerged from central China late last year.

The people on quarantine are kept under a 14-day quarantine. If they are placed together and if anyone is diagnosed with the infection during that period, the quarantine will add another 14 days. The longer several thousand people are cohoused, it goes on to propagate waves of infection. A better way is to divide these people into smaller groups and quarantine them separately. Why quarantine children <15 years when the virus is not risky for them. Why not separate elderly people with comorbid conditions at high risk of death and quarantine them separately in one-to-one or small groups. Why allow people to celebrate and have cultural programs during quarantine, as was seen in India, when people danced together with surgical masks during quarantine period. Ventilation system can connect one room to the other. There has been concern that the coronavirus can spread through pipes. Stress and anxiety suppress the immune system, thus rendering people more vulnerable to contracting the virus. Quarantine them the way it was done in TB sanatoriums with both sun-balconies and a rooftop terrace where the patients would lie all day either in beds or on specially designed chairs.

Standard Respiratory Droplets Precautions

At triage: Surgical 3 layered mask to the patient; Isolation of at least 1m distance, cough etiquette and hand hygiene

Droplet precautions: Three layer surgical mask by patients, their contacts and health care workers, in an adequately ventilated isolation room, health care workers while caring with the secretions should use eye protection, face shields/goggles. One should limit patient movement, restrict attendants and observe hand hygiene.

Contact precautions: When entering room - gown, mask, goggles, gloves – remove before leaving the room; Dedicated equipment/disinfection after every use; Care for environment- door knobs, handles, articles, laundry; Avoid patient transport and practice hand hygiene.

Airborne precautions when handling virus in the lab and while performing aerosol-generating procedures. Room should be with negative pressure with minimum of 12 air changes per hour or at least 160 litres/second/patient in facilities with natural ventilation. There should be restricted movement of other people and all should use gloves, long-sleeved gowns, eye protection, and fit-tested particulate respirators (N95 or equivalent, or higher level of protection)

Public

Strict self-quarantine if sick with flu like illness: 2 weeks

Wash your hands often and for at least 20 seconds with soap and water or use an alcohol-based hand sanitizer.

Avoid touching: Eyes, nose, and mouth with unwashed hands.

Avoid close contact: (3-6 feet) with people who are sick with cough or breathlessness

Cover your cough or sneeze with a tissue, then throw the tissue in the trash.

Clean and disinfect frequently touched objects and surfaces.

Masks

Surgical 3 layered Masks: For patients and close contacts

N 95 Masks: For health care providers when handling respiratory secretions.

Lab tests

There are two ways to detect a virus: through the genetic material DNA or RNA and to detect the protein of the virus. The rapid tests look at the protein. It takes 8-12 weeks to make commercial antibodies. Currently, for the diagnostic tests, PCR is being used which gives a turnaround in 1-2 hours. BOTH the upper respiratory tract (URT; nasopharyngeal and oropharyngeal) AND lower respiratory tract (LRT; expectorated sputum, endotracheal aspirate, or bronchoalveolar lavage) Use PPE in the lab Use viral swabs (sterile Dacron or rayon, not cotton) and viral transport media In US, in January, all testing had to be done in CDC laboratories. However, on February 4, the US FDA issued an emergency-use authorization for the CDCs COVID-19 Real-Time RT-PCR Diagnostic Panel, allowing its use at any CDC-qualified laboratory in the United States. Lab precautions: BSL 2 (3 for viral culture labs)

Treatment

No proven antiviral treatment. With SARS, in 6 months the virus was gone and it never came back. Pharmaceutical companies may not spend millions to develop a vaccine for something which may never come back. Secondary infection, E. coli, is most likely the cause of death of the patients in the Philippines and Hong Kong. A combination of lopinavir and ritonavir showed promise in lab in SARS. Combination of lopinavir, ritonavir and recombinant interferon beta-1b was tried in MERS. Scientists in Australia have reportedly recreated a lab-grown version of COVID 19. Chloroquine had potent antiviral activity against the SARS-CoV, has been shown to have similar activity against HCoV-229E in cultured cells and against HCoV-OC43 both in cultured cells and in a mouse model. Thailand: Oseltamivir along with lopinavir and ritonavir, both HIV drugs. Experimental drug: From Gilead Sciences Inc., called remdesevir (started on 6th Feb as a trial) Russia and China drug: Arbidol, an antiviral drug used in Russia and China for treating influenza, could be combined with Darunavir, the anti-H.I.V. drug, for treating patients with the coronavirus. (The COVID-19 virus shares some similarity to HIV virus also) PVP-I mouthwashes and gargles are known to reduce viral load in the oral cavity and the oropharynx. PVP-I has high potency for viricidal activity against hepatitis A and influenza, MERS and SARS The Drug Controller General of India has approved the "restricted use" of a combination of drugs (Lopinavir and ritonavir) used widely for controlling HIV infection in public health emergency for treating those affected by novel coronavirus. In SARS, people were put on long-term steroids ending with immunosuppression and late complications and death. The current protocol is short-term treatment.

Confirmed case

A person with laboratory confirmation of COVID 19 infection, irrespective of clinical signs and symptoms.

Severe acute respiratory infection ( SARI)

An ARI with history of fever or measured temperature ≥38 C° and cough; onset within the last ~10 days; and requiring hospitalization. Absence of fever does NOT exclude viral infection

SARI in a person, with history of fever and cough requiring hospital admission, with no other etiology that can fully explain the clinical presentation (clinicians should also be alert to the possibility of atypical presentations in immunocompromised patients)

AND any of the following:

a) A history of travel to Wuhan, Hubei Province China in the 14 days before symptom onset; or b) the disease occurs in a health care worker who has been working in an environment where patients with severe acute respiratory infections are being cared for, irrespective of place of residence or history of travel; or c) the person develops an unusual or unexpected clinical course, especially sudden deterioration despite appropriate treatment, regardless of place of residence or history of travel, even if another etiology has been identified that fully explains the clinical presentation

OR A person with acute respiratory illness of any severity who, within 14 days before onset of illness, had any of the following exposures:

a) close physical contact with a confirmed case of COVID 19 infection, while that patient was symptomatic; or b) a healthcare facility in a country where hospital-associated COVID 19 infections have been reported

Uncomplicated illness

Patients with uncomplicated upper respiratory tract viral infection, may have non- specific symptoms such as fever, cough, sore throat, nasal congestion, malaise, headache, muscle pain or malaise. The elderly and immunosuppressed may present with atypical symptoms. These patients have no signs of dehydration, sepsis or shortness of breath

Mild pneumonia

Patient with pneumonia and no signs of severe pneumonia. Child has cough or difficulty breathing + fast breathing: fast breathing (in breaths/min): <2 months, ≥60; 2–11 months, ≥50; 1–5 years, ≥40 and no signs of severe pneumonia

Other signs of pneumonia may be seen: chest indrawing, fast breathing (in breaths/min): <2 months, ≥60; 2–11 months, ≥50; 1–5 years, ≥40.

Diagnosis is clinical; chest imaging can help exclude complications.

Acute Respiratory Distress Syndrome

Onset: new or worsening respiratory symptoms within a week of known clinical insult.

Chest imaging: bilateral opacities, not fully explained by effusions, lobar or lung collapse, or nodules.

Origin of edema: respiratory failure not fully explained by cardiac failure or fluid overload. Need objective assessment (e.g. echocardiography) to exclude hydrostatic cause of edema if no risk factor present.

Moderate ARDS: 100 mmHg < PaO2/FiO2 ≤200 mmHg with PEEP ≥5 cm H2O, or non-ventilated)

Severe ARDS: PaO2/FiO2 ≤ 100 mmHg with PEEP ≥5 cmH2O, or non- ventilated)

PaO2 not available: SpO2/FiO2 ≤315 suggests ARDS (including in non-ventilated patients)

Oxygenation (children; OI = Oxygenation Index and OSI = Oxygenation Index using SpO2)

Bilevel NIV or CPAP ≥5 cmH2O via full face mask: PaO2/FiO2 ≤ 300 mmHg or SpO2/FiO2 ≤264

Signs of organ dysfunction include: altered mental status, difficult or fast breathing, low oxygen saturation, reduced urine output, fast heart rate, weak pulse, cold extremities or low blood pressure, skin mottling, or laboratory evidence of coagulopathy, thrombocytopenia, acidosis, high lactate or hyperbilirubinemia.

Children: suspected or proven infection and ≥2 SIRS criteria; of these, one must be abnormal temperature or white blood cell count

Septic shock

Adults: persisting hypotension despite volume resuscitation, requiring vasopressors to maintain MAP ≥65 mmHg and serum lactate level >2 mmol/L

Children: any hypotension (SBP <5th centile or >2 SD below normal for age) or 2-3 of the following: altered mental state; tachycardia or bradycardia (HR <90 bpm or >160 bpm in infants and HR <70 bpm or >150 bpm in children); prolonged capillary refill (>2 sec) or warm vasodilation with bounding pulses; tachypnea; mottled skin or petechial or purpuric rash; increased lactate; oliguria; hyperthermia or hypothermia

Common Myths

People receiving packages from China are not at risk of contracting the COVID 19 as the virus does not survive long on objects, such as letters or packages. There is no evidence that animals/pets such as dogs or cats can be infected with COVID-19. Pneumococcal vaccine and Haemophilus influenza type B (Hib) vaccine, provide no protection against COVID-19. Regularly rinsing the nose with saline does not protect people from infection with COVID-19 or respiratory infections although it can hasten recovery from the common cold. There is no evidence that using mouthwash will protect you from infection with COVID 19 although some brands or mouthwash can eliminate certain microbes for a few minutes in the saliva in your mouth. There is no evidence that eating garlic protects people from COVID-19. Sesame oil does not kill the new coronavirus. Chemical disinfectants that can kill the COVID-19 on surfaces are bleach/chlorine-based disinfectants, either solvents, 75% ethanol, peracetic acid and chloroform. People of all ages can be infected by COVID-19. Older people, and people with pre-existing medical conditions (such as asthma, diabetes, heart disease) have increased odds of becoming severely ill with the virus. Antibiotics do not work against viruses. To date, there is no specific medicine recommended to prevent or treat COVID-19.

Trolls and conspiracy theories: Not validated and are fake news

COVID-19 is linked to Donald Trump,and US intelligence agencies or pharmaceutical companies are behind it. Eating snakes, wild animals or drinking bat soup cases coronavirus infection. Keep your throat moist, avoid spicy food and load up on vitamin C. Avoiding cold or preserved food and drinks, such as ice cream and milkshakes, for "at least 90 days". Experts have been aware of the virus for years. The virus was part of Chinas "covert biological weapons programme" and may have leaked from the Wuhan Institute of Virology. Linked to the suspension of a researcher at Canadas National Microbiology Lab. China wants to kill 20,000 COVID-19 patients is totally false. The site is linked to a sex website.

Experts Opinions on COVID-19

“I think this virus is probably with us beyond this season, beyond this year, and I think eventually the virus will find a foothold and well get community-based transmission and you can start to think about it like seasonal flu. The only difference is we dont understand this virus”

Dr. Robert Redfield

Director, CDCUS Centers for Disease Control and PreventionFeb. 13, 2020

“What makes this one perhaps harder to control than SARS is that it may be possible to transmit before you are sick. I think we should be prepared for the equivalent of a very, very bad flu season, or maybe the worst-ever flu season in modern times.”

“We are estimating that about 50,000 new infections per day are occurring in China. [...] It will probably peak in its epicenter, Wuhan, in about one-month time; maybe a month or two later in the whole of China. The rest of the world will see epidemics at various times after that.”
