COVID-19. GVA Updated Review and Maritime Recommendations

Coronavirus COVID-19 GVA maritime recommendations

Today the whole world is extremely concerned over COVID-19 – coronavirus that was completely unknown till December 2019.

Four months passed after the first case in Wuhan, the capital of Hubei Province in China, and the total number of confirmed cases as of April 28th exceeded 3 000 000, affecting 185 countries.

Without a doubt the entire world has been affected in some way or another by the COVID-19 pandemic. Almost every country has imposed restrictive measures focusing on viral-surveillance effort and consequent effects minimization.

Unsurprisingly, the maritime community has also been affected in a big way. The crews of the vessels more than ever need to be advised by medical professionals providing key practices for safety and protection as well as the guidelines for the crew officers when facing a suspected case on board or onshore.

The aim of this guidance prepared by Global Voyager Assistance is to repot what is it – COVID-19, and what to do for avoiding its affect.

Geography of COVID-19

The best known resource for the geographical overview for the confirmed cases worldwide is the John Hopkins University Center for Systems Science and Engineering (CSSE) COVID-19 Interactive Map:

John Hopkins CSSE COVID-19 Interactive Map

The more detailed information on the geography of the virus is available at the World Health Organization in its daily COVID-2019 Situation Reports:

WHO COVID-2019 Situation Reports

With the rapidly changing situations at the regional level, for the deeper overview of the cases certain countries, visiting the national healthcare authorities COVID-19 informational resources is the best way to receive the updated information on the epidemic geography at the country level.

So what is the coronavirus (COVID-19)?

Coronavirus is not something new to healthcare professionals. It is one of the numerous groups of viruses causing diseases ranging from the common cold to more severe one. SARS-CoV-2 which is known as COVID-19, a new strain of coronavirus that has not previously been detected in human population, is one of the seven types of coronavirus, including the ones that cause Middle East Respiratory Syndrome (MERS) and Sudden Acute Respiratory Syndrome (SARS). Although viruses in this family vary in terms of disease caused and how they pass from host to host, their basic structure is the same. Some coronaviruses transmit easily from person to person, while others do not.

What are the symptoms of COVID-19?

The symptoms can occur between 2 and 14 days from exposure to the virus. That is why the 14-day quarantine period is used for people with likely exposure to the new coronavirus. The symptoms range from more minor ailments like tiredness, fever, sore throat, loss of smell and taste, dry coughing, a runny nose and diarrhea to more serious symptoms like difficulty in breathing, high fever and painful coughing.

The severity of COVID-19 symptoms can range from very mild to severe. Some people may have only a few symptoms, and some people may have no symptoms at all. The proven fact is that people with pre-existing health conditions like chronic pulmonary problems, heart disease, diabetes, chronic kidney, oncological or severe autoimmune diseases, or who have compromised immune system are more likely to experience severe symptoms that may finally lead to fatal outcomes.

Can COVID-19 be transmitted from person to person?

Yes. Coronavirus is spread most often by what are known as "respiratory droplets" from an infected person — the little secretions we generate when we sneeze or cough. That is why the spread of the virus between people generally occurs through close contact. Close contacts are those people who have been face to face with a person infected with the virus for at least 15 minutes, or were in the same closed space with an infected person for at least 2 hours at the distance less than 1 meter.

How is COVID-19 diagnosed?

The current testing available for COVID-19 includes diagnostic tests and antibody blood tests. Diagnostic tests are provided by obtaining nose and throat swabs and sending them for laboratory testing. Testing is done by real-time polymerase chain reaction (RT-PCR) – the research method coming the standard for infectious diseases diagnostic. This kind of test shows if the patient currently has an infection of COVID-19. Depending on the medical facility some tests are point-of-care tests, meaning results may be available in several hours or less. Other tests must be sent to a laboratory to analyze, a process that takes 1-2 days once received by the lab.

Antibody tests, also called serologic tests, check the blood for antibodies - proteins that help fight off infectious agents - showing if the patient has had a previous infection. A serologic test may not be able to show if the patient has a current infection, because it can take 1 to 3 weeks to make antibodies after the disease occurs.

It is not yet determined if having antibodies to COVID-19 can protect someone from getting infected with that virus again, or how long that protection might last. Scientists are doing studies to answer these questions.

What is the treatment for COVID-19?

Since the first version of the guideline has been published no specific antivirus treatment for COVID-19 is still available. In the meantime, many coronavirus treatments are being developed and tested worldwide. Among them are drugs that have been used to treat malaria and autoimmune diseases, antiviral drugs that were developed for other viruses, and antibodies from people who have recovered from COVID-19. Some critically ill patients with COVID-19 have been treated with high doses of intravenous vitamin C. However, there is no clear or convincing scientific evidence that it works for COVID-19 infections, and it is not a standard part of treatment for this new infection.

Anyway clinical management includes provision of symptomatic care for those with mild illness, and optimized supportive care for those with severe disease.

We kindly remind on сhecking with the doctor before starting any kind of treatment.

Is COVID-19 vaccination available?

No vaccine is currently available, and the focus of the healthcare authorities all over the world has been the containment of the virus through preventive measures to limit and slow down widespread transmission.

Does COVID-19 affect shipping industry?

The challenges arising from COVID-19 outbreak affect not only seafarers navigating to countries with detected cases of coronavirus, but also the whole shipping market and trading. The shipping industry is now seeing the impact of the coronavirus outbreak followed by markets disruptions and ports restrictions: unfortunately, its impact on the maritime community obviously has become greater than that of previous outbreaks of SARS or other pandemic infections.

What about port restrictions?

The local port agents and correspondents normally possess with the most updated information on the restrictions implicated by the local healthcare authorities in the rapidly changing situation. The early and continuous checks with the situation at port of calls is highly recommended till the seize of the pandemic alert.

What are the general preventive measures?

Among COVID-19 risk groups are people with compromised immunity, first of all one has to follow the simple general recommendations, which allow the human immune system to work correctly:

1. Avoid sleep deficit.

2. Perform simple-support exercises to be in good physical shape.

3. Eat healthy food avoiding any new or suspicious dishes.

4. Get the flu vaccine as well as all necessary vaccines depending of vessel routes to avoid contraction of a disease that would deteriorate COVID-19 state if it occurs.

Pre-boarding precautions

1. Careful inspection of crewmembers in order to detect symptoms:

- general weakness
- general chills
- fever over 37,5C
- cough
- runny nose
- sore throat
- headache
- muscle ache
- loss of smell and taste

2. Collecting information on contacts with mentioned above symptoms the crewmember had for the last 14 days.

3. Collecting information on the country the crewmember came from as well as countries he/she crossed for the last 14 days.

On board precautions

COVID-19 has a relatively low resistance in the external environment: the virus can survive for several hours on smooth surfaces as well as for several days at suitable humidity and temperature. For example, in an environment with the humidity of 40% and the temperature of 20 C, the virus can remain virulent for up to five days.

The main risks of viral shedding on board are related to the sanitary condition of the commonly used areas and the duration of the route.

Self-protection is the key measure of COVID-19 prevention. The measures do not generally differ from what one should take to avoid contraction of flu:

1. Frequent hand washing using soap and hot water or alcohol-based (at least 65-70%) hand sanitiser for 20 seconds

2. Avoidance of touching the face including mouth, nose and eyes with unwashed hands

3. Crewmembers should be encouraged to cover their mouth and nose with a disposable tissue when sneezing, coughing, wiping and blowing the nose, then dispose of the used tissue immediately and wash the hands

4. If a tissue is not available, crewmembers should cover their nose and mouth with flexed elbow when sneezing or coughing
Note: sneezing or coughing into hands may contaminate objects, surfaces or people that are touched

5. Crewmembers should aim to keep at least 1 meter distance from people having fever, cough or other common cold/flu symptoms

6. Clean and disinfect frequently touched surfaces especially when someone is ill. Any food and non-food supplies delivered to the vessel from the shore must also be thoroughly disinfected. Refer to recommendations for disinfection in suspected COVID-19 case below

7. Meat, milk or animal products should always be handled with care

8. Daily pre-duty self-body temperature measurement is strongly recommended

9. Report immediately to the Master if any of the flu symptoms appear

What about face masks?

While medical face masks do not guarantee 100% protection for the wearer, they still considerably reduce the likelihood of infection, especially if there is a risk of exposure when interacting with persons from outside the vessel.

Wearing of face mask by a person is absolutely essential when any of the flu symptoms persist as well as if the person is taking care of another one with suspected COVID-19 infection. The maximum length of use of mask is 1 hour. After use, the mask shall be disposed to a container with any antiseptic solution.

However, unlike simple facemasks, respiratory masks, like № 95, FFP2 and FPP3 protect against aqueous and oily aerosols, smoke and fine dust, verifying protection from avian flu, SRAS, tuberculosis, as well as viral and bacterial respiratory pathogens. The classifications signify the number of particulates filtered out by the mask, the FFP2 filters 94%, №95 filters 95% and FFP3 filters 99%. These respirators are highly recommended to use during the COVID-19 pandemic.

Vessel precaution measures:

Masters of vessels should secure the following items to the stock.

- Personal protection equipment (PPE) and decontaminants:
1. Disposable gowns/suits. Boilersuit disposable polypropylene, IMPA code 190568.
Rough estimate: 1 gown for 3 crew members a day – 130 pcs of gowns for 20 crew members for 20 days.
Note: the number of suits for vessels bounding for Asia is 3 times as for other destinations.

2. Disposable medical masks, Face Mask Disposable, IMPA code 391283 or analogue, 100 pieces per set.
Rough estimate: 8 masks for one person a day – 32 sets for 20 crew members for 20 days.

3. Disposable gloves, Gloves Disposable Vinyl, IMPA code 190135 or analogue, 100 pieces per set.
Rough estimate: 6 sets for 20 crew members for 20 days.

4. Antiseptic Gel Bottles, Hand Liquid Disinfectant Antiseptic for hand washing - IMPA code 550263 or analogue, 500 ml per bottle.
Rough estimate: 10 bottles for 20 crew members for 20 days.

5. Alcohol- or chlorine-containing solutions for surface treatment, 10 litters per canister.
Rough estimate: 20 canisters for 20 days.

- Medical pack on board:
1. Thermometers, IMPA codes 391846/392037/391422, 2 pcs.

2. Paracetamol tab 1000 mg.
Rough estimate: 1000 mg every 6 hours – 1600 tabs for 20 crew members for 20 days.
Note: Paracetamol is used as an antipyretic and analgesic drug only for treatment, not for prophylaxis.

3. Azithromycin tab 500 mg.
Rough estimate: 1 tab (500 mg) per a day (once) – 400 tabs for 20 crew members for 20 days.
Note: these antibiotics are used for respiratory tract infections treatment, which are the most common complications of COVID-19.

4. Ringer's lactate, injection solution, w/o IV set and needle, 1000ml.
Rough estimate: 3 litters per a day for 25% of all crewmembers – 300 litters for 20 crew members for 20 days.
Note: this is a fluid maintenance solution used for complicated cases.

Managing a suspected case on board

A suspected case is:

- A patient with severe acute respiratory infection that is fever and cough AND with no other aetiology that fully explains the clinical presentation AND a history of travel to or residence in the countries with established community transmission of COVID-19 during the 14 days prior to symptom onset

- A patient with any acute respiratory illness AND at least one of the following during the 14 days prior to symptom onset: contact with a confirmed or probable case of COVID-19 disease OR visiting a healthcare facility where patients with confirmed or probable COVID-19 disease were treated.

If a suspected case is identified the ship should start an outbreak management plan on board, even before lab results confirm an infection.

1. Isolation

Crewmember should be isolated immediately in either isolation ward, cabin, room or quarters with the door closed. The body temperature should be regularly monitored and recorded. To relieve the symptoms Paracetamol is used as 1000 mg orally every 6 hours.

Any person entering the isolation room should wear disposable gowns, gloves and medical masks. The patient should strictly wear the medical mask as well.

2. Reporting to the next port of call

The Master is required to inform the health authorities at the next port of call to determine if the necessary capacity to transport, isolation and care for the individual is available. The ship may need to proceed to another nearby port if the local capabilities are insufficient.

The Master should check the latest port entry requirements for the next port of call and be ready to provide:

- Health declaration

- Body temperature list

- Information list on crewmembers with symptoms

- Information list on previous port calls

- Information list on crewmembers’ travel history (concerning the regions with unfavourable epidemiologic situation)

3. Ships ventilation system should be turned off to avoid air exchange with the rest of the accommodations.

4. The area outside the isolation room should be allocated, where individual protective gear can be removed and disinfected after visiting the patient.

5. Disposable cups, plates and other cutlery should be used, disposing them as contaminated items.

6. Maintaining high level cleaning and disinfection measures during ongoing on-board case management.

7. If a COVID-19 returns positive, any crewmembers who were in close contact with the patient should go under onshore quarantine.

How laboratory tests are provided?

If testing for COVID-19 is recommended, the vessel will be directed to berth at a port and the ill person can be transferred to a medical facility. Laboratory examination of clinical specimens for suspect cases should be undertaken by the competent authorities who will then inform the vessel’s officers about the test results.

Key tips for cleaning and disinfecting when COVID-19 is suspected on board

In case of coronavirus symptoms presented it is advisable to clean all areas with application of the disinfectant only on surfaces/items having direct contact with the COVID-19 suspect, especially the areas, which may have been occupied by the person.

Clean the hard, non-porous surface first with detergent and water, and then apply disinfectants according to the product instructions. Ensure correct concentrations and sufficient exposure time for effective disinfection. Carefully remove porous materials, where possible, such as upholstery, rugs, and carpeting that have been in contact with the suspect case. Launder in accordance with the product instructions or dispose of the materials as described below.

All used PPE and all soiled items (used tissues, disposable masks, pillows, blankets, mattresses not covered with an impermeable plastic covering, etc.) in the contaminated areas, should be treated as Bio hazardous waste and stored in an impermeable plastic bag labelled biohazard. The bag should be tied up, not reopened and disposed according to the ship protocol for clinical waste. If incinerator is available on board, then waste must be incinerated. If waste must be delivered ashore, then special precautions are needed and the port authority should be informed before waste delivery.

How Telemedicine can be of help for you?

Telehealth should increasingly be viewed as a key way to help fight the COVID-19 outbreak, especially among the maritime community.

While COVID-19 couldn’t be diagnosed through a telemedicine consultation, the telemedical session with a qualified physician will assist the Master and his crew with better understanding of the medical problem by professional assessment of the range of medical services required avoiding immediate deviations. The 24/7 Telemedicine services includes performing an initial remote assessment, determining if a crewmember needs any diagnostic tests, offering treatment recommendations based on the medical inventory on board and giving recommendations regarding hospitalization ashore or medical evacuation.

How medical transport of the diagnosed COVID-19 crewmember is possible?

Currently there is a lot of restrictions for cross-border transport of confirmed COVID-19 patients. Moving a COVID-19 patient by commercial air carrier is completely prohibited. The restrictions for air ambulance transport are caused by both sanitary concerns for cabins of the air ambulance aircrafts and the cross border transfer of such patients implicated by the healthcare authorities of various countries. We are monitoring the travel restrictions through our own network of partners around the Globe on literally hourly basis, the restrictions are only increasing for some of the areas.

However, there is no complete impossibility of transferring a SARS COVID-19 patient by a very limited number of aircrafts, crews and medical teams today. Along with the use of medical aircrafts equipped by special modules available (like for Ebola cases), there will additional costs be involved on top of regular life-support medical transfer budget due to the use of unique equipment and additional safety measures for the medical team, the crews and the cabin.

The possibility for air medical transport of a certain patient from A to B in each and every case will be subject to scrutiny in assessed details.
