Coronaviruses are a gathering of infections that cause sicknesses in warm blooded animals, including people, and fowls. In people, the infection causes respiratory contaminations which are regularly mellow yet, in uncommon cases, can be deadly. In dairy animals and pigs they may cause loose bowels, while in chickens it can cause an upper respiratory infection.
Symptoms can range from mild illness to pneumonia. Some people will recover easily, and others may get very sick very quickly. People with coronavirus may experience:
The virus originated in the city of Wuhan, in the central Chinese province of Hubei, late last year. It has since spread to Chinese cities including Beijing and Shanghal. A small number of isolated cases have been confirmed elsewhere in Asia. Two cases have been reported in the United States.
Coronaviruses are a large family of viruses that usually infect animals but can sometimes evolve and spread to humans. Symptoms in humans include fever, coughing and shortness of breath, which can progress to pneumonia.
Local authorities in China have quarantined the cities of Wuhan and Huanggang, which have a combined population of 17 million. Travel bans were in effect Friday for at least 10 cities, including Wuhan, where the virus was first identified, and Huanggang.
WHO is not recommending any broader restrictions on travel or trade at this time. Physicians recommended basic hygiene, including washing hands with soap and water and avoiding touching eyes, nose or mouth.
The WHO is advising people in affected areas to follow standard procedures to reduce the chance of catching the virus. They include hand and respiratory hygiene as well as safe food practices.#Source BBC
International travellers: practice usual precautions
Coronaviruses are a large family of respiratory viruses that can cause diseases ranging from the common cold to the Middle-East Respiratory Syndrome (MERS) and the Severe Acute Respiratory Syndrome (SARS). In case of symptoms suggestive of acute respiratory illness before, during or after travel, the travellers are encouraged to seek medical attention and share travel history with their health care provider.
Public health authorities should provide to travellers information to reduce the general risk of acute respiratory infections, via health practitioners, travel health clinics, travel agencies, conveyance operators and at points of entry.
WHO’s standard recommendations for the general public to reduce exposure to and transmission of a range of illnesses are as follows, which include hand and respiratory hygiene, and safe food practices:
The current outbreak originated in Wuhan city, which is a major domestic and international transport hub. Given the large population movements, expected to significantly increase during the Chinese New Year in the last week of January, and the observed human to human transmission, it is not unexpected that new confirmed cases will continue to appear in other areas and countries.
With the information currently available for the novel coronavirus, WHO advises that measures to limit the risk of exportation or importation of the disease should be implemented, without unnecessary restrictions of international traffic.
According to Chinese authorities, all unnecessary or non-essential large-scale public gatherings will not be approved during the Spring Festival, which starts on 25 January in China.
Conduct exit screening at international airports and ports in the affected areas, with the aims early detection of symptomatic travelers for further evaluation and treatment, and thus prevent exportation of the disease. while minimizing interference with international traffic.
Exit screening includes checking for signs and symptoms (fever above 38°, cough), interview of passengers with respiratory infection symptoms leaving the affected areas with regards to potential exposure to high-risk contacts or to the presumed animal source, directing symptomatic travelers to further medical examination, followed by testing for 2019-nCoV, and keeping confirmed cases under isolation and treatment.
Encourage screening at domestic airports, railway stations, and long-distance bus stations as necessary.
Travelers who had contact with confirmed cases or direct exposure to potential source of infection should be placed under medical observation. High-risk contacts should avoid travel for the duration of the incubation period (up to 14 days).
Implement health information campaigns at points of entry to raise awareness of reducing the general risk of acute respiratory infections and the measures required, should a traveler develop signs and symptoms suggestive of infection with the 2019-nCoV and how they can obtain assistance.
Advice for entry screening in countries/areas without transmission of the novel coronavirus 2019-nCoV
Evidence shows that temperature screening to detect potential suspect cases at entry may miss travelers incubating the disease or travelers concealing fever during travel and may require substantial investments. However, during the current outbreak with the novel coronavirus 2019-nCoV, the majority of exported cases were detected through entry screening. The risk of importation of the disease may be reduced if temperature screening at entry is associated with early detection of symptomatic passengers and their referral for medical follow up.
Temperature screening should always be accompanied by dissemination of risk communication messages at points of entry. This can be done through posters, leaflets, electronic bulletin, etc, aiming at raising awareness among travelers about signs and symptoms of the disease, and encouragement of health care seeking behavior, including when to seek medical care, and report of their travel history.
Counties implementing temperature screening are encouraged to establish proper mechanism for data collection and analysis, e.g .numbers of travelers screened and confirmed cases out of screened passengers, and method of screening. In implementing entry screening, countries should take into account national policies and capacity.
Public health authorities should reinforce collaboration with airlines operators for case management on board aircraft and reporting, should a traveler with respiratory disease symptoms is detected, in accordance with the IATA guidance for cabin crew to manage suspected communicable disease on board an aircraft.
Previous advice with regards to procedures for a sick traveller detected on board a plane and requirements for IHR capacities at points of entry remains unchanged (see WHO Advice published on 10 January 2020).
WHO advises against the application of any restrictions of international traffic based on the information currently available on this event.
If you have fever, cough and difficulty breathing seek medical care early and share previous travel history with your health care provider;
When visiting live markets in areas currently experiencing cases of novel coronavirus, avoid direct unprotected contact with live animals and surfaces in contact with animals;
The consumption of raw or undercooked animal products should be avoided. Raw meat, milk or animal organs should be handled with care, to avoid cross-contamination with uncooked foods, as per good food safety practices.
WHO technical guidance on surveillance and case definitions, laboratory guidance, clinical management for suspected novel coronavirus, home care for patients with suspected novel coronavirus, infection prevention and control, risk communications, disease commodity package, and reducing transmission from animals to humans is available on the WHO website.
Call ahead to a healthcare professional if you develop a fever and symptoms of respiratory illness, such as cough or difficulty breathing, and have been in close contact with a person known to have COVID-19 or if you live in or have recently traveled to an area with ongoing spread. Tell your healthcare professional about your recent travel or contact. Your healthcare professional will work with your state’s public health department and CDC to determine if you need to be tested for COVID-19.
Household members, intimate partners, and caregivers in a nonhealthcare setting may have close contact2 with a person with symptomatic, laboratory-confirmed COVID-19 or a person under investigation. Close contacts should monitor their health; they should call their healthcare provider right away if they develop symptoms suggestive of COVID-19 (e.g., fever, cough, shortness of breath). Close contacts should follow:
